EM-waveform-gen

Arduino-based waveform generator for electromagnets

This project is intended to control high-current electromagnets that cannot be controlled with a standard function generator due to current requirements. It features:

• self-contained integrated user interface and display
• 3 options for waveforms:
  1. DC voltage
  2. Positive pulse wave
  3. Positive and negative pulse wave
• user-set frequency

Hardware requirements (all sourced from Sparkfun):

• Sparkfun RedBoard Qwiic (DEV-15123)
• Sparkfun 20x4 SerLCD - RGB Backlight (Qwiic) (LCD-16398)
• Sparkfun Button Pad 2x2 - Breakout PCB (COM-09277)
• Sparkfun Button Pad 2x2 - LED Compatible (COM-07836)
• 4x LED - RGB Clear Common Cathode (COM-00105)
• 4x Diode Small Signal - 1N4148 (COM-08588)
