You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

This setup allowed [Alex] to control all 128 LED’s with just seven bits, but it was too slow for him. His solution was to control the multiplexers with counter IC’s. The Arduino can just ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There … ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

Völker calls the paintings (which are technically photographs) Variations on Pi, and to make ’em, he cobbled together an Arduino-controlled, LED-equipped robot — a sort of cross between a ...
