Week 4 : Analog In – Digital Out

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.

  1. Glad you went back and noted the solution later. A couple of things on the documentation:

    Include code and circuit diagrams, particularly of things you’re describing or trying to understand. It can help explain the process.

    The detail photos are helpful for reading your notes. More like that last one especially, where you can see close-up what’s going on.
