Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

The original RGB LED chain controller has one button that changes the LED lighting mode. There are 10 modes in total. In this project, I created a controller from Arduino Nano, a relay, DIP switch and ...

This project shows a LED matrix panel with 64x64 full RGB pixels driven by a ATMega-2560 Arduino. I added a Real Time Clock RTC_DS3231 to show the time. This display was created to help teachers in my ...

Among quantitative analysis techniques, molecular absorption methods in the ultraviolet/visible region are the most commonly employed in chemical laboratories worldwide. In general, the absorbance ...
