Connect the LED to PWM pin (e.g., D9) through a resistor. Connect the middle pin of the potentiometer to A0. Connect the other two potentiometer pins to 5V and GND. The potentiometer sends an analog ...

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 – ...

This project uses two Arduino boards to control the speed of a DC fan using a potentiometer. Three LEDs indicate different speed ranges: red for slow, green for medium, and blue for fast. The serial ...

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 ...
