Defect Detector – Schematic

Here you can see the servo motor to the left that was connected to our A3BU which is being controlled by PWM. The duty cycles ranged from 15 (middle), 10 (left), and 20 (right)


In order to connect the servo motor and pressure sensor to the A3BU, first we had to look up what colors were used for the power, ground, and signal for the servo and then pins that were used for the pressure sensor. The servo motor is wired up to an external 5V DC power supply with an orange cable connected to the PWM pin on the A3BU. The pressure sensor was connected to a 3.3V power supply from the board and was connected to the ADC pin of the A3BU. The A3BU received power from a laptop.
