For this project I used: Arduino Uno, A Servo Motor, A Potentiometer, Conductive Fabric, Thin Copper Wire, Hookup Wires, Breadboard and an LED.
This project is a prototype of a bigger project that I envisioned. The idea is to create a series of inputs, the outputs of which act as an input for the next sensor – a chain of inputs and outputs that work to light an LED. In the work presented, the circuit connects a potentiometer to the servo motor, controlling its rotation. As the motor touches the conductive fabric, the copper wire completes the LED circuit.
Challenge: When building this circuit, I couldn’t get my servo motor to rotate synchronously with my potentiometer. The problem was with how I had connected my potentiometer to Power, Ground and Analog Input.
