Text on I2C-LCD1602 Display written over Web-Page

Sometimes it might be useful to write a text which should be displayed on a LCD display without any cabling, that is possible to do over your own Wi-Fi network and a NodeMCU ESP8266 module. And the project uses ONLY 4 wires as the LCD1602 gets addressed over the I2C bus. Let us remember WHAT the I2C bus is in our previous tutorial:

• First Steps with the Arduino-UNO R3 and NANO | Maker, MakerED, Coding | RFID RC522 Tag-Card Reader with LCD1602-I2C
• …

Check out the wiring below please, ONLY 4 wires plus 2 for the power supply connections:

.

Let us have a look on the video below who shows how it works:

.

.

SO, knowing now how it works, let us have a look on the Sketch (Code). I changed a bit the code, as I am using an I2C LCD1602 and I added as well some more text displayed on the LCD1602 display. Check below, please, the original code. I will explain WHAT could (should) GET changed later with a screenshot of the changes and/or a download…

The Arduino code and the library for this project can be found at the links below. The library has to be saved in the Arduino libraries folder of the same name:

• https://www.dropbox.com/s/4by3peoau2s25wz/esp8266weblcd.ino?dl=0   ===> The .ino file (Arduino Sketch/Code)
• https://www.dropbox.com/s/l5qe8ko64mu0037/esplcdweb.h?dl=0               ===> The esplcdweb.h file for creating the web-page
• …

 

Find below, please, my changed code (Sketch) for downloading:

• ESP8266-WebText-I2C-LCD1602-Code
• …

The download is a text file created with OpenOffice, copy the content and place it into a new Sketch on the Arduino IDE. ALL you have to do now is to change some lines, e.g.:

• in line 47: Enter your SSID
• in line 48 Enter your Wi-Fi Network Password

See PIC below, please:

.

This should work for you now; in case of that you wouldn’t see the display working find here the trouble-shooting:

Mostly it is that your LCD1602 uses a different I2C-Address and/or that the ESP8266 isn’t allowed in your network for security reasons, to make sure check my blog post here, please:

Here below a working Sketch which shows how it is working: for security reasons you won’t see my SSID, nor my real IP-Address! 😉

What should get be taught and learned more in 21st Century while using ICT?

.

Possible instructions for educators on how they can work together with the learners. Knowing the tools for 21st Century Learning is primordial to give quality courses. One very important knowledge who needs to get taught is “Critical Thinking“; it brings out also new ideas and the courage to become an engager and helps to try to build a better world in both worlds: “Real World” and “Virtual World” (Internet)!

.

Teaching “Critical Thinking” to your students and learners is a MUST for a world who is changing very fast (sometimes too fast…) so that a lot of people can’t follow anymore… But by knowing “Critical Thinking” people would be catching up more quick, so very important!!!

.

===> Critical Thinking is a catalyst when well used together with Social Medias! <===

.

When talking about Critical-Thinking then automatically we should talk also about Responsibilities! Find out more in my course Not Only Rights, But Also Responsibility!?

HOW COULD THAT BE IN PRACTICE???

First of all I recommend you to read some books to understand, I recommend books from Howard GARDNER and Daniel GOLEMAN.

.

• 5 Minds For The Future (Howard GARDNER)  to understand what the world needs for abilities fom students in 21st Century…

• The Disciplinary Mind: the mastery of major schools of thought, including science, mathematics, and history, and of at least one professional craft.
• The Synthesizing Mind: the ability to integrate ideas from different disciplines or spheres into a coherent whole and to communicate that integration to others.
• The Creating Mind: the capacity to uncover and clarify new problems, questions and phenomena.
• The Respectful Mind: awareness of and appreciation for differences among human beings and human groups.
• The Ethical Mind: fulfillment of one’s responsibilities as a worker and as a citizen.

What should get be taught and learned more in 21st Century while using ICT?

.

Being online since 1998 and giving courses about ICT (Information and Communication Technologies) more than 10 years, the practice and my online excursions show me that IT-Security and Internet-Safety are not yet taught enough. Best practice example is that from 100 computers (Windows) there was only one (1) who was correctly secured and didn’t contain any malware, only some cookies… In my private life when going out and talking with people there comes mostly of time out the discussion about IT-Security with people who I know and others who are following the discussion, and when knowing through discussion that I have good knowledge about IT-Security they ask me also for advice…

.

So, with the consent of the owner of these Cafés, Pub’s I arranged an appointment with these people and I checked their computers (Windows machines) in these places while the owner and other present customers could have a look on how I did it and where I explained them also why and how malware is penetrating the computer, by also showing them later on How-To protect their computers. Customers were also allowed to ask questions, where I gave them the links of my free courses and tutorials… That’s the positive part of my so called “on the field adventures and practice” where customers were youth as also adults and seniors…

.

The negative one is that from +/- 30 computers and Laptops I checked there was NO ONE who was secure and ALL of them were infected with malware, even one was acting as a malware server!!!

---

So, what does this show us!?

1. There isn’t enough information from Education (or too theoretical) around about how to get protected
   • Why? Perhaps teachers and educators are Mac users and not prepared for such a serious task!? Lack of REAL knowledge about IT-Security! IT-Security can ONLY get taught seriously by people who have practice with it!
   • Lack of IT-Security practice knowledge in general, so how can one be able then to bring over the right knowledge!?
   • Learners don’t feel it necessary, why? Bad teaching, sorry! Not ONLY a society problem as some say! A teacher doesn’t give up till he finds the right way that it will get understood even that he must learn himself some new stuff to make it more interesting for the learners!
2. There isn’t enough information from Government to adults and seniors around about how to get protected (or too theoretical)
3. When courses are giving from Education and Government they are too theoretical and don’t give the necessary practice to learners for protecting their computers
4. IT-Security can ONLY have best results when done with practical workshops!
• ===> Confucius: Tell me, and I will forget. Show me, and I may remember. Involve me, and I will understand. – Confucius, 450 B.C.
1. Education and Government are publishing with 21st Century Technology but still doing it with 20th Century knowledge! They have to improve and to employ people with the necessary practice knowledge and skills!
2. There is a need to create so called “IT Security Help Points (Places)” where people with practice knowledge and skills are available to give advice on the place and where visitors can bring their computers to check for vulnerabilities and infections, as I did as a volunteer, but these people should get payed for it!

Critical Thinking Questions and memes

Questions to make everybody awake for Critical-Thinking and hopefully to see one day practical courses and workshops:

.

• Can YOU drive a car (and this also safely) ONLY by getting theoretical courses and advice? YOU would surprise me, seriously, a BIG LOL for that 😉 So how YOU will expect that someone could surf secure with his computer as it is “visually seen” the “vehicle” with whom users are driving on the “Data High Way” (Internet)!????
• Would YOU allow somebody who doesn’t have the knowledge about how-to use the breaks (IT-Security) of a car and the traffic rules (Internet-Safety) to take part of the traffic in public in real life? But that’s what is happening actually in virtual life (Internet)! Think about, please 😉
• Someone who doesn’t have the knowledge to use his computer (the vehicle in virtual life/Internet) is a potential danger for the COMMUNITY!!!
• Do YOU know who is profiting from such a lack of knowledge and naivety!? Cybercrime is, they use YOUR computer to earn money, funny isn’t it!??? Wake up!!!

.

Would like to know how the actual worldwide situation is about IT-Security? Check this cartoon, please. Created by IT-Security experts and Antivirus manufacturers; and this is the Reality!

 THE OBJECT of Teaching…

.

. The object of teaching a child is to enable him to get along without a teacher. Elbert Hubbard (1856-1915) American author, editor and printer. Keywords:  . 21st century learning and teaching, narration and interaction, real and imaginary level, learning on an vivid and understandable way, learning with videos on a visual way, passion, cross-subject education, cross-border thinking, interconnectedness of our global world, different media and disciplines, emotional and motivating effects, motivation, inspiration, solving the problems of the future by critical thinking… . NB: Personally I would feel proud to see one of my PLN (Personal Learning Network) to create a worksheet with screenshots and to send me the link which of course I would include in my courses, come on folks, waiting for it 😉 .
