This project is a simple LED dimmer circuit that uses Arduino's PWM (Pulse Width Modulation) capability. The user can smoothly adjust the brightness of an LED using a potentiometer or digital input.

Analog Input. PWM Output. Full Control. Fourth step in the embedded grind. This isn’t just about lighting up LEDs—it’s about using analog input to shape digital output. 3 LEDs. 1 potentiometer.

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...
