For ANY projects WE will create there are books and also online documentations which WE will need to learn from and to GET NEW ideas as well. I will propose to YOU a selection of books and links which I have read and learned from as well; links which I use as well to incorporate into my tutorials as ALSO YouTube videos to learn from.

I bought these books on Amazon, find the references for ordering them here, please:
WE are really lucky today because of ICT and the internet to learn about electronics; it was NEVER THAT easy as today!! WE can find simulation software as well as schematics drawing software online and/or for download as for FREE (Open Source and FREEWARE). I remember 49 years ago when I was 12 years old and tinkering around, using curiosity to find out on the How-To things were working by disassembling them, whatever it was… Later, I was working after school (12 1/2 years old starting till 20 years…) around on any place in the village (farmer, café, gardening for private persons, etc.) to earn some money to be able to buy me necessary stuff for my electronics lab…
Nowadays WE GET all the necessary stuff online and WE DON’T need anymore to purchase an oscilloscope and a Multimeter for measuring as one can simulate everything straight on through FREE software. I am feeling HAPPY for that as it allows LEARNERS from any society status to learn about electronics!
Please check below for useful articles on Software:

The author Gust MEES is ICT Course Instructor, ”Member of the Advisory Board” from “Luxembourg Safer Internet” (LuSI), BEESECURE, Official Partner (Consultant) from the Ministry of Education in Luxembourg, project “MySecureIT“, Official Partner from the Ministry of Commerce in Luxembourg, project “CASES” (Cyberworld Awareness and Security Enhancement Structure).
The author was also a winner of an electronics contest (Germanic countries) in 1979 and got his project published in the “Electronics Magazine ELO”).
I propose to work with system when WE use strip-boards; thus meaning: preparing them ALL the same way. Any electronics project will need a power supply, so WE will start with the power supply which will mostly be a 9 Volt battery. WE will use the outside strips to connect them to plus and minus and WE will ALSO provide a diode (1N4007) to protect against polarity reversal. As a newbie in electronics this might be the best way to protect you to destroy the electronic parts if + and – would get reversed 😉 With normal rectifier diodes the power supply voltage will typically drop by 0.8 volts. WE will have then ONLY 8.2 Volts which is enough in most cases.
WE will solder also a PCB-Connector (Printed Circuit Board Connector) where we can feed the strip-board with the power supply.
.
SO, as WE will solder a bit, it will be also a soldering training before we start on more serious projects later 😉
Check below please how the finished project will look, which we will discuss in detail on the How-To. WE use a 100 mm x 75 mm strip-board (CONRAD 529531 – 62 for 2,19€).
.

Necessary material
.

.
In above image I used a 2 pin screw terminal from CONRAD (1192188 – 62) for 0,28€ and for the wire I choose from a “Wire Kit from Velleman” (60 m from different colors).
full core, 0.2mm²
colours: 5 metres : white / blue / brown / green / yellow / orange / grey / violet + 10 metres : black / red
external diameter: 1.4 mm
max. voltage: 60 V
max. current: 4.3 A
PVC insulation
tinned CU
AWG24
.
.
To make sure to have proper bent edges; I suggest to bend the diode (1N4007) over the left-hand side shown “Wire Bender” (CONRAD 425869 – 62 at 3,29€).
.
.
First start to solder the 2 pin screw terminal in the middle of the strip-board, followed by the diode (1N4007). Now measure the distance and cut the wires. For the red wire (Plus) it will be 4 cm (3 cm distance), the blue wire (Minus) will be 6 cm (5 cm distance). Take the electronics cutter and strip off o,5 cm of the insulation at each end and bend it. Put it into the holes in the strip-board and solder it. P.S.: WE will use the red wire for the Plus (+) and the blue wire for the Minus (-) of the power supply; that are internationally conventions in electronics. Sometimes for the Minus (-) is also used the black color (see 9 Volt battery clip).

Solder the wires and cut off the stick out wire close to the soldering with the electronics cutter.

When WE want to start with electronics there is a little bit theory to learn as well; in electronics there are special symbols who get used in schematics. Any component (even a battery) has its own symbol. In the following tutorials and projects, WE will learn by easy step-by-step WHAT they are and HOW to make OUR PracTICE (to GET used to it…) with them. I am certainly NOT a friend of learning by heart, BUT symbols need to get learned that way to understand schematics of electronics!
.
Symbols used in this tutorial: battery, resistors, LEDs and diodes…
Here below a small description about the How-To to work with strip-boards in general:
.
.
After viewing the above tutorial YOU will understand. The above tutorial uses the FREE software “Fritzing” which WE will use as well in the next blog posts; you can download it here:
Here the wiring and soldering on the strip-board, as well as the parts list:

As You have remarked, I added ALSO a resistor and a LED (Light-Emitting Diode); the red (could also bee a green one) LED is lightning when the power supply (9 Volt battery) is connected. SO, YOU might solder the two components (330 Ohm resistor and LED) as well, not mandatory BUT it will give YOU a bit more training on soldering and alerts YOU to NOT solder when it is on!! NEVER work on whatever project with connected (switched on) power supply <===> Safety first!
WHY has the resistor a value of 330 Ohm?
In above example we used a 5 mm red LED with this characteristics: 2.25 Volt and 20 mA current (that’s the maximum values which DON’T have to become higher otherwise the LED will get destroyed) and as power supply we use a 9 Volts battery. WE will use the “Online Calculator” to calculate the value of the resistor. First let us do some mental calculation, there WE DON’T need any calculator. WE have a 9 Volts battery and the LED will have maximum 2.25 Volts, so “9 V – 2.25 V = 6.75 V” which needs to get taken away from the LED to avoid destruction.
.
..
THAT value of 337.5 Ohms doesn’t exist! Resistors are manufactured by following <===> In 1952 the IEC (International Electrotechnical Commission) decided to define the resistance and tolerance values into a norm, to ease the mass manufacturing of resistors. These are referred to as preferred values or E-series, and they are published in standard IEC 60063:1963. These standard values are also valid for other components like capacitors, inductors and Zener diodes. The preferred values for resistors were established in 1952, but the concept of the geometric series was already introduced by army engineer Renard in the 1870s.
By checking the below link, WE will see that the closest value is 330 Ohm. BTW: The symbol for “Ohm” is “Ω“; SO, we write 330 Ω. Tip: You find it in the “Special Characters” in any editing software.
In the above website is a video integrated which explains very well about the How-To of that norm, give it a try.
.
MY experience described in ONLY some phrases: Give the LEARNers, students (whatever age) the freedom of LEARNing without squeezing THEM into a FRAME and concentrate on guiding them as a coach by analyzing THEIR behavior and show them the How-To to become self-directed learners, autodidacts. SHOW THEM ALSO up from the beginning WHAT THE <===> LEARNing Path <===> will be with design of it and explain THEM that they could design themselves it with a short introduction on the How-To. THEY will learn the ICT-PracTICE which will help them once out of the <===> #SchoolCocoon <===> to be ready for Life-Long LEARNing and to be able to adapt very quickly in the workforce! WHEN YOU show the LEARNers, students <===> WHAT the profit is for THEIR private life <===> YOU will engage them very quickly 😉 AND DON’T teach THEM more as necessary, propose them some links to go further ONLY for those who want!!
Check ALSO (Up from 11 years old, give THEM THE confidence THEY need to grow):
WHAT’S my message and WHY did I create this blog post!?
Well, I will encourage all youth and also adults, seniors, oldies to become <===>Life-Long LEARNers <===> and staying Up-To-Date with their knowledge, especially concerning their skills in ICT, called NOW <===> #eSkills <===>! In the modern world YOU will change YOUR job probably +/- 12 times in YOUR working career, it is very rare to stay life-long in the same job and/or same company!!! SO… The workforce is looking for people with ICT skills which YOU mostly didn’t learn at school, right!?
Bring in YOUR kids to such creative makerplaces WHERE THEY can develop (and perhaps parents as well…) THEIR creativity and GET interested in something WHICH could boost THEIR interest into ICT in their future 😉
YOU won’t have (mostly) the time to learn by visiting courses, right!? START to become Life-Long LEARNers by LEARNing on YOUR OWN pace, by becoming <===> Autodidacts <===> Self-Directed LEARNers. YOU are able to, I did it, so can YOU!? 😉
I found a job because of my ICT eSkills and I am STILL LEARNing on a daily base routine for being Up-To Date with my <===> Professional Development <===>, even being retired NOW! THE pleasure of LEARNing!
I did THE <===> ICT PracTICE <===> and THAT’S WHAT the workforce needs!!!
Due to my eSkills I could share my knowledge AND expertise ALSO with the below mentioned as well as to a broad range of visitors from around the globe!
Practical Tip: LEDs are transparent, so the Cathode (Minus) looks always a bit larger as the Anode (Plus).
.
.
.
When working with electronics WE need to learn a bit theory and mathematics, BUT DON’T worry, it is very easy! First of all which is mandatory, is the “OHM’s Law“. YOU DON’T need to calculate! 😉 There is an online calculatorwho will do the job for YOU! Click the image below please to access the online calculator and play a bit around with it to get used to it, have fun.

For most people it is very difficult to understand IT-Security and also the need to apply it…. To me it looks sometimes like that people see a computer as a modern typewriter and/or a game console, but that’s not the case, I will try to explain to you a computer in a visual manner so that you might able to understand better why there is a need to protect your computer and also why a computer is in danger to get avirus, trojan, and other malware infections. Why a computer could become a possible Cyber-Weapon who is attacking web-sites and perhaps also your Government’sweb-sites!
But let us start first with some funny videos who will explain to you also aboutIT-Security in a visual way…
.
.
.
.
Introduction
Try every time to see a computer as a technical machine, which it is, and when connected to Internet it is your vehicle who navigates you trough the Data Highway (Internet). So, vehicles as you know need sometimes maintenance and may also represent (even new ones) technical problems which may effect the security for you and also for the community.
.
===> Nobody is perfect! <===
.
Check the video below who explains very well about all the malware, YOU will understand then the need to secure your computer.
.
.
.
.
Some questions to wake you up to critical-thinking, if you permit 😉
Explaining the dangers of infected computers and the dangers to your Government also:
Would you allow a person entry with contagious disease into your home or institution? An epidemic would be the result!
An infected #computer is same ===> epidemic danger!
YOU know that when driving your car that you could hit a person by accident!? Do you realize that this could happen also virtually (in Internet) with your computer!? This person’s computer would get also infected and this person would need to repair its computer which would cost money as most people don’t know how to get rid of an infection! Are YOU aware that YOU are responsible for that!?
Are YOU a good patriot? Would YOU help to defend your country and Government against attacks? So do so also on Internet! Learn the basics of IT-Security!
Do YOU know that Cyber-Criminals earn more money than others with Drugs, and that with YOUR computer!?
Do YOU know that Cyber-Criminals are better organized as Police and FBI and…?

Check the videos below and take your time; bookmark this site and come back when having time to watch them… .
Internet (the virtual world) is exactly the same as the real world. There are bad and good guys. We need to protect us and the community against the bad guys!
Any computer with Windows, Mac and Linux Operating Systems and…, are vulnerable! Nobody is perfect!
We can’t trust any web site! Some web sites are infected and malicious! By “drive-by-download” we will infect also our computer by visiting such a prepared web site!
Use my mentioned sources to learn yourself about IT-Security, Cyber-security, Cyber-war, Cyber-warfare, Cyber-crime and… Find below the keywords as a guide for yourself on How-To and with what tools to prepare your personal course(s)… I will provide soon a new course about how you could prepare your courses from my own 14 years practice, as a guide for you… which of course you could adapt to your own needs…
.
What we should learn and what we will learn in these courses…
Keywords and guidelines for teachers educators instructors and learners (students + teachers), self learning included:
Community:
once connected to Internet we are part of millions of other users of Internet! Each one is responsible for others!
By using Social Media(Hashtag is#SoMe) this is even more accurate as more people are getting reached!
Responsibility
Critical Thinking
Competences
Ignorance + Naivety of users is the Power of Cyber-criminals…
