Lab 2: Servos

Let's Open a Door!

Compared to DC Motors, servo motors have a third cable that needs to connect to a board (like an Arduino) in order to work. Let’s explore how this works.


  • Arduino Uno
  • Micro Servo
  • IR Sensor
  • LED
  • Wires
  • Breadboard
  • Cardboard 
  • Glue
  • Print

Tutorial taken from instructables

Step 1

Let’s print a house. Paste the image in a cardboard so it can stand up and cut three sides of the door so we can open it and close it.

Step 2

Connect the components as follows.

Step 3

Mount your new door system into your house!

Use a clip to connect the horn of the servo to your door.
