The PCA9685, designed for LED dimming and servo control (25 mA max per channel), is repurposed to drive four N20 DC motors via two TB6612FNG H-bridge modules. PWM outputs on channels 0–5 and 8–13 control speed and direction. STBY pins are tied to 5V logic. An ADS1115 provides potentiometer-based position feedback. An Arduino Uno manages I2C communication and serial control from a Python GUI. Component Abuse: The PCA9685 is used far outside its intended low-current application, with its PWM signals driving high-current motor H-bridges, turning a precision LED controller into a scalable motor driver.
