New demo code which transforms eduArdu in Makey Makey and tutorial how to use with Scratch 3 is uploaded to GitHub.

Here is the result from above code:

eduArdu OSHW educational board new demo and tutorial updated on GitHub

eduArdu-3

The eduArdu-BotKit demo is uploaded on GitHub. This code control the robot with sound.

New LED_Matrix_Light library is uploaded. It contains only Clear, SetPixel, GetPixel, ClearPixel, Line, DrawRectangle, UpdateMatrix functions and do not take lot of memory like the LED_Matrix library which contains text scrolling and fonts.

Two more demo for capacitive buttons are add. One make sound depend on capacitance, the other prints the value of the capacity measured.

Programming eduArdu with Arduino explains how to install Arduino and some basics of programming for beginners, like what are arrays, variables, etc. It may be used as practice of what is learned in C/C++ class in school.

eduArdu-BotKit transforms your eduArdu in small bot

eduArdu-4

eduArdu-BotKit consist of two continual rotation servo motors, two 32mm wheels, ball wheel and converts eduArdu in small robot:

Here is small video clip of small demo how to control eduArdu robot with clap of your hands.

OSHW High precision calibrated digital air quality CO2, temperature, humidity, air pressure sensor board with UEXT connector

MOD-ENV4

Analog gas and air quality sensors have quite negligent readings. They need special calibration to measure correctly.

This is why CCS811B digital air quality sensor by AMS is so interesting. It can measure indoor air quality and CO2 content with digital readings from 400 up to 29206 ppm.

MOD-ENV has CCS811B and BME280 digital precise temperature, humidity and air pressure sensor assembled together. Both operate through I2C and are low power with sleep modes which makes them perfect for enviroment monitoring and IoT.

ESP32-POE, ESP32-POE-ISO, ESP32-EVB has UEXT connectors and can directly connect to MOD-ENV.

The price of MOD-ENV is between EUR 14.36 and 15.95 depend on quantity.

If you need more memory and micro SD card for your Arduino project -OLIMEXINO-2560 is with 256K Flash and SD card on board

OLIMEXINO-2560

OLIMEXINO-2560 is Arduino Mega2560 like board which keeps ports conversion but adds UEXT connector to connect our wide range of modules and sensors, works on 5V and 3.3V, and has on board micro SD card for file storage and logging.

Power supply uses DCDC convertor with input range 6-15VDC when OLIMEXINO-2560 works on 5V and 5-15VDC when OLIMEXINO-2560 works on 3.3V.

TuxCon organized Arduino Day in PMG Konstantin Velichkov in Pazardzhik

arduino-day

Saturday 16.03.2019 was Arduino Day and celebrated all around the world by Arduino enthusiasts. On Arduino web site there is dedicated page with map where all events are listed.

TuxCon organized Arduino Day in PMG “Konstantin Velichkov” – Pazardzhik. The youngsters were around 20 and we split them in 5 teams with mentors.

eduArdu was used as educational board and it was really pleasant surprise to see how dedicated were all participants – they worked 4 hours and didn’t want to take a rest.

Some of them has never seen Arduino, but studied the existing demo codes and start to modifying them. Some even try to make their own snake game on the LED matrix. Another nice code was done for controlling the eduArdu RGB LED remotely with cell phone via the IR receiver, we expect these codes to go as pull requests to our GitHub repository soon 🙂

Obviously their teachers did good job, no wonder they got so many prizes:

TuxCon is open to organize such events in other schools too, if you want your school to have similar event please contact TuxCon.

 

First Steps with Snap4Arduino and eduArdu tutorial in Bulgarian and video is GitHub

Our Bulgarian customers often blame us that we post and make documents in English, but we really think that if one decided to work in IT industry and deal with programming and electronics should learn English and supporting documentation in two languages just double the burden for us.

eduArdu is educational board targeting kids so it’s a different story. This is why we made small tutorial how to use eduArdu with Snap4Arduino in Bulgarian language and uploaded it to GutHub in PDF and ODT format.

On Youtube we uploaded video for the same with English text.

So we hope now both English and Bulgarian customers will be pleased 🙂
