Arduino PWM As you may know, two PWM outputs of Arduino Uno are linked to the timers. For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned ...

1. Arduino Board: The heart of the project. An Arduino Uno or similar board will work perfectly. 2. Rotary Encoder: Used for adjusting the frequency and amplitude of the generated signals. 3.

If you’re interested in building your own laser sky effect generator, you’ll need a few key components: an Arduino Uno, a laser module, mirrors, motors to spin the mirrors, a photoresistor, an ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.
