GROVE Pressure Sensor BME280 on Normal LCD1602 I2C Display

In a previous tutorial WE have seen the Grove Beginner Kit for Arduino from SEEEDSTUDIO https://gustmees.wordpress.com/2020/08/03/grove-beginner-kit-for-arduino-seeedstudio-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/, and THE BREAKOUT to use the different modules with OWN Code examples.

WE were ALSO using the OLED module as a BREAKOUT in this tutorial https://gustmees.wordpress.com/2020/10/21/grove-beginner-kit-for-arduino-seeedstudio-the-breakout-temperature-humidity-on-oled-display-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/

In this tutorial WE will use the BREAKOUT of the GROVE Pressure-Module BME280 together with a NORMAL I2C LCD1602 display, ONLY 4 wires to connect. At that moment I didn’t yet receive my ordered GROVE LCD1602 display, so the suspense was great to find out… I was curious to find out if that would ALSO work and it did with a few changes of code.

Check out the wiring below, please:

GROVE Pressure Sensor BME280 on GROVE LCD1602 Display

In a previous tutorial WE have seen the Grove Beginner Kit for Arduino from SEEEDSTUDIO https://gustmees.wordpress.com/2020/08/03/grove-beginner-kit-for-arduino-seeedstudio-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/, and THE BREAKOUT to use the different modules with OWN Code examples.

WE were ALSO using the OLED module as a BREAKOUT in this tutorial https://gustmees.wordpress.com/2020/10/21/grove-beginner-kit-for-arduino-seeedstudio-the-breakout-temperature-humidity-on-oled-display-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/

In this tutorial WE will use the BREAKOUT of the GROVE Pressure-Module BME280 together with a GROVE LCD1602 display. As the GROVE LCD1602 display is not included in the Grove Beginner Kit for Arduino, WE will need to buy it! Here below the address:

Connections of the GROVE BME280 and the GROVE LCD1602 on I2C BUS

Connections of the GROVE BME280 and the GROVE LCD1602 on I2C BUS

.

Well, as you can see in above photo there is NO cabling!! You just need to connect the connectors from the BME280 and the LCD1602 to the I2C BUS. Less than a minute work and you are ready to upload the code, which you will find in below link:

.

The GROVE LCD1602 display is a RGB display, meaning that you can change its color to RED, GREEN, BLUE! Play around with the code to experiment…

Thoughts about WHAT to choose as Xmas gift for kids in a Technology driven world

Thoughts about WHAT to choose as Xmas gift for kids in a Technology driven world

.

.


WHAT gifts to buy for the kids for Xmas and Holidays?

Every year the same question, isn’t it!? WHY not thinking about to buy gifts from where and with that the kids will learn? It might be good to have a look on WHAT are the skills required for the future from youth, students, learners and upon that making your choice! Actually (2020) the trends are in the maker scene and coding scene! Engineers, coding people and ICT specialists are needed, the workforce, industry is searching!!

WHAT is the Coding Scene?

Coding is THE 21st Century skill. Coding enhances creativity, teaches young people to cooperate, to work together across physical and geographical boundaries and to communicate in a universal languageTechnology is part of our life, and coding brings it closer to you!

.

I invite you to read my blog posts below, please:

MY selection of CODING Hardware for beginners

Well, I started myself years ago as a NEWBIE in Coding and so I tried out different stuff, whereby I became a fan of ARDUINO. Here below my gift selection for Christmas (Xmas) which I recommend:

.

ARDUINO-UNO-STARTERKIT-1

 

.

.

.

.

Elegoo Smart Robot Car Kit for Arduino

Temperature/Humidity on OLED Display | THE Breakout

In a previous tutorial WE have seen the Grove Beginner Kit for Arduino from SEEEDSTUDIO https://gustmees.wordpress.com/2020/08/03/grove-beginner-kit-for-arduino-seeedstudio-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/, now WE make THE BREAKOUT to use the different modules with OWN Code examples.

You can also take the modules out and use Grove cables to connect the modules. To do so, you need a sharp cutter, see PIC, please.

.

.

My recommendation for sharp cutters, which I use as well:

.

 

.

Once cut out you have made the BREAKOUT and in this case the two modules “OLED Display 0.96 inch” and “Temperature/Humidity” modules are ready to get connected to the main module. NOW we have to connect them through the delivered connection cables. Here below a picture:

.

.

As you can see, the OLED-Module is connected to the I2C connector, while the “Temperature/Humidity-Module” is connected to the “D3” connector. See PIC below, please:

.

.

SO WHY the “D3” connector for the “Temperature/Humidity-Module”?! Well, let us have a look on the code:

.

.

As you can see in this shown part of the code, there is marked ===> “#define DHTPIN 3“, SO it should GET connected to the “D3-connector” on the main board! If you use “D4” or whatever connector, SO you should change the code from “3” to “4” and so on!!! Give it a try and play around with it for understanding 😉

.


Temperature/Humidity on OLED Display | THE Code

Well, the two connections with the provided cables with connectors took ONLY a few seconds, ISN’T it? 😉 Let’s GO now to upload the code. Open your “Arduino IDE“, click on “NEW“, erase the few lines marked in there, make a “Copy&Paste” from the mentioned Code below and paste it in the “Arduino IDE (NEW)” and upload it, here below the code:

.

.

As you can see there is a “special” indication on the display, THE “Heat Index“, WHAT is it?! I encourage you to read my following tutorial which explains:

 

Have fun learning with PracTICE and stay tuned for next adventures of learning 😉

Grove Beginner Kit for Arduino | SEEEDSTUDIO |

SEEEDSTUDIO asked me through LinkedIn to make a cooperation with them for reviewing a NEW Arduino, the “Grove Beginner Kit for Arduinoproduct which I accepted. Today I received the stuff which in the next days I will play around a bit and create Blog posts (Tutorials) about it, stay tuned…

FIRST impressions:

I ordered it on 28-07-2020 on the site of SEEDSTUDIO and it arrived on 03-08-2020 @02H58 PM, delivered by DHL. Actually very quick from China to Luxembourg!!

Unpacking my order:

Nice cardboard with lots of TIPS printed on it. The box is sealed with 3 circular glued plastic which I had cut through with scissors, BAD IDEA, as I damaged the cardboard while NOT knowing that the box was meant as a whole playstation as itself (see photos, please)… Here the company could improve please, thanks! My constructive critics! 😉

.

.

As long as that glued plastic problem ISN’T resolved, use a sharp cutter to cut off the glued circular plastic as I couldn’t remove it by hand!

.


Reading the online Manual

Well, NOTHING to say against it, it is well done!! Please check it here below:

There are professional STEP-BY-STEP instructions so you can’t make mistakes!!

.


Getting started

ALL you have to do is to connect the USB-Cable to the PC, Laptop, which is in the right sight of the box (see step 2 in the PIC below please) to start. [Start Text from WiKi] Grove Beginner Kit for Arduino is one of the best Arduino Beginner Kit for beginners. It includes one Arduino compatible Board and 10 additional Arduino sensors and all in one-piece of PCB design. All the modules have been connected to the Seeeduino through the PCB stamp holes so no Grove cables are needed to connect. Of course, you can also take the modules out and use Grove cables to connect the modules. You can build any Arduino project you like with this Grove Beginner Kit For Arduino. [End Text from WiKi]

My review

Well, I can recommend this product for beginners by 100%!! Up from the beginning beginners can find out HOW things work with just plugging the USB cable to the PC, Laptop, computer. It’s a GREAT way to bring Coding to STEAM students, Maker’s, MakerED and Maker Spaces!

I didn’t yet using the Breakout possibilities, I DON’T overwhelm you with TOO MUCH information, that will GET discussed in next tutorials, BUT looks promising as NO need to plug single cables, ALL done by ONLY one connector!!!

.

Please check the videos below to understand how the GROVE System works.

..

 


WHERE to order it?

You can GET it here actually (04-08-2020):

In previous tutorial we were using an LCD1602 display, this time we will use an LCD2004 display which gives us the opportunity to display on four (4) lines. That enables us to display more accurate text.

The wiring is exactly the same as already mentioned in previous tutorial, there is ONLY to make a few changes in the code, please check:

The complete Code fr an LCD1602 display could get downloaded in “.doc” format below.

Download and open the document, copy it and bring it in a NEW Sketch of the Arduino IDE. Upload it to the Arduino Nano and have fun with it!

SO, once uploaded we will need to change some code to make it work for an LCD2004 display, we will see how below.

Social Distancing Monitor, Arduino NANO and I2C OLED Display

In times of the Coronavirus-Crisis (Covid_19), it might be GOOD to respect the 2 meters distance to avoid getting infected!!! But not everybody can estimate distances, nor are ALL persons respecting the 2 meters rule!!! So came the idea to build an easy to realize gadget, which measures the distance when the 2 meters are not respected.

First of all, like usual, I was searching the internet to find out if there isn’t already such a project around. And YES, there is one; I found a tutorial with an Arduino UNO with provided code as well. Please check below:

In a previous tutorial WE were already using a “Social Distancing Monitor with Alarm, Arduino NANO and I2C LCD1602 Display“, check below please for revision:

Social Distancing Monitor with Alarm, Arduino NANO and I2C LCD1602 Display

In times of the Coronavirus-Crisis (Covid_19), it might be GOOD to respect the 2 meters distance to avoid getting infected!!! But not everybody can estimate distances, nor are ALL persons respecting the 2 meters rule!!! So came the idea to build an easy to realize gadget, which measures the distance and gives an alarm when the 2 meters are not respected.

First of all, like usual, I was searching the internet to find out if there isn’t already such a project around. And YES, there is one; I found a tutorial with an Arduino MEGA and a LCD1602 ISP with provided code as well. Please check below:

 

This tutorial gave me the idea to start. Instead an Arduino MEGA, I used an Arduino NANO; and instead of an LCD1602 ISP, I used an LCD1602 I2C.

Thus meaning: it needs a bit to adjust the code in the sketch in the above mentioned tutorial and it’s LESS cabling, wiring needed to connect the I2C LCD1602 display.

WE played around already with I2C LCD1602 in my tutorial below, please check:

SO, here we go for the wiring… Below the wiring for the I2C LCD1602 with the Arduino NANO

:

I2C LCD1602 PINOUT-Arduino NANO

.

LCD-I2C-PINOUT-ARDUINO


Connecting the HC-SR04 Ultrasonic Sensor:

 

Connections to the Arduino NANO:

Vcc+ gets connected to + 5V

GND to GND

ECHO gets connected to PIN 10

TRIGGER gets connected to PIN 9


Connecting the Buzzer for the acoustic Alarm:

 

The + sign of the Buzzer gets connected to PIN 8 of the Arduino NANO and the other pin to GND!

Below you see the prototype with wiring.

.


The code

Here below see a preview of the Code:

Valentine’s Day is around: GET creative with an LED Matrix and an Arduino!

[Start Text Wikipedia] Valentine’s Day, also called Saint Valentine’s Day or the Feast of Saint Valentine,[2] is celebrated annually on February 14. Originating as a Western Christian feast day honoring one or two early saints named Valentinus, Valentine’s Day is recognized as a significant cultural, religious, and commercial celebration of romance and romantic love in many regions around the world. [End Text Wikipedia]

A tradition worldwide around is to give flowers to his loved one, so WHY NOT ALSO a small electronic device which shows a heart on a LED Matrix?!! It is NOT expensive and gives a certain “special” feeling to your loved one 😉 And ALSO, I give you the “ready code” to start it straight on. You don’t need to create the “Heart Character” before, BUT I will give you ALSO the link to the tutorial who explains very well the How-To!

Please check below the tutorials with the wiring and the code:

 


The wiring

.

WIRING-LED MATRIX-ARDUINO

Click image, please, to access its origin.

..

There are ONLY five (5) wires to connect and the code works with the ARDUINO UNO and the ARDUINO NANO.

.


How-To make custom characters

There is a software available to create custom character codes for the LED-Matrix, please check the tutorial below:

.

OR, use an online character-generator, see PIC below for example, please:

 

LED MATRIX GENERATOR-CHARACTER-CODE

.

Doesn’t look that difficult, isn’t it?! 😉

.

Anyway, find below the ready to use code, please:

All you need now is to bring it into a box for a nicer presentation and to give it as a gift to your love!

Secret tip: Use as well a LCD with scrolling text, where you can program then a special personal text message for your love. Please check my tutorial below:

Keywords necessary for me to create this blog post: Arduino UNO R3, Arduino NANO, LCD 1602, I2C Bus, coding, learning to learn, learning by doing, LED Matrix, Valentine’s Day, Character Generator for LED Matrix,
