  1. 1

    Let's begin by creating the circuit! Connect the following bits in this orders: power + pressure sensor + bargraph + wire + vibration motor

  2. 2

    Next, draw a shape for your back massager handle on cardboard and cut it out. Our back massager is shaped like an arm, what will yours be shaped like?

  3. 3

    When you are designing your back massager handle, make sure you include some holes for your Bits. You will need 1 hole large enough for a ping pong ball to fit through. You should also design a hole large enough for the pressure sensor to be accessible. Last, but not least, you will need a hole that is large enough for lights from the bargraph.

    Then, use an x-acto knife to cut a hole in the ping pong ball. Use a glue dot to secure the metal vibration motor inside of the ping pong ball. Squeeze the pressure sensor to feel it the ping pong ball buzz!

  5. 5

    You are almost done! Now you just have to add your Bits to the back massager handle that you designed.

    Press the pressure sensor and let the relaxation begin!
