PWM Signal Generator

Introduction: PWM Signal Generator

About: I'll be doing lots of interesting things here, but mainly :electronics (arduino, analog and digital), computers (old and new), programing (C# and python), linux (administration and hacking). Geeky enterteinmen…

Circuit is very easy to build all you need is:

  • Arduino UNO
  • OLED display module
  • Few wires
  • 3mm LED
  • 8ohm speaker
  • Servo motor
  • 10k ohm pot
  • 3x10k ohm trimmer pots
  • 2x1uF caps

Step 1: Program Circuit

Step 2: Filtering PWM

What if you need sine wave or spike wave, you can easly filter those out of PWM

Step 3: How Can I Use PWM

Answer is simple just hook it up to speaker, LED or servo
