Simple PWM Speed Control
Budget: $10 – $30 USD
Looking to set up a DC motor speed control with a 128 X 32 OLED 0 - 100% bar graph using a rotary encoder switch.
Arduino Beetle (Leonardo)
Rotary switch encoder; Push ON/OFF, rotate clockwise ti increase speed (counterclockwise to decrease). 3 inputs.
OLED, 128X32, SDL/SDA 2 outputs.
LED, Green, 1 output, HIGH when on.
Mosfet, NPN, 1 output.
If you have any questions please let me know...
