Simple PWM Speed Control
Budget: $250 – $750 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.
