“Replacing servos with DC motors + potentiometers for precise, cost-effective robotic arm control.
Circuit Connections
- Connect the potentiometers to analog input pins of the L293D Shield or Arduino board. The pins are A0, A1, A2, and A3, with the positive and ground wires connected together to 5V+ and GND pins.
- Connect the N20 DC motors to the Adafruit Motor Shield.
- Ensure proper power supply connections for both the Arduino and the motor driver.
- Connect the Arduino board to your computer via USB for serial communication.”
