HAND WASH Timer

Wire up the sensor and servo according to the wiring diagram.

Then VCC -> 5V on the Arduino

Trig -> Pin 9 on the Arduino

Echo -> Pin 10 on the Arduino

GND -> GND on the Arduino

For the Servo Motor, use the Male / Male wires to connect the following:

Red Servo Wire (5V) -> Vin on the Arduino

Black Servo Wire (GND) -> GND on the Arduino

Orange Servo Wire (Signal) -> Pin 7 on the Arduino

Assemble the Timer

Cut out a servo sized hole

open the Arduino software Make sure to install the NewPing, EWMA, and Queue libraries from the Arduino library manager before running the sketch!
