Picture of Bluetooth Mouse With Ultrasonic Sensor and Photocell

So, a little introduction as to why I made this project. I'm currently looking to adopt a kitten into my new house. And after going trough some playable things for cats, I thought: why not make a toy myself. So, I made a Bluetooth mouse. You can control it using the app I made for android phones. Also, I made two modes. A input off mode where the mouse only responds if some object is close behind its back. And the normal input on where the user of the app can 'drive' the mouse.

Step 1: Materials

Picture of Materials

For the mouse you will need:

  • 1x Arduino Uno
  • 1x Breadboard
  • 1x Solder board
  • 2x Gearmotor with 360 decrees offset
  • 1x 10k Ohm resistor
  • 1x Arduino driver board L298N Dual H Bridge
  • 1x HC-05 Bluetooth adaptor
  • 1x Photocell Light resistor
  • 1x Ultrasonic sensor
  • 1x Piece of wood
  • 2x Wheels that are able to fit the gearmotor
  • 20x Tie-wraps
  • 20x Female - Female Jumper Wires
  • 20x Male - Male Jumper Wires
  • 1x Phone with android on it
  • 1x LED strip
  • 1x 12v Battery
  • 3x Buttons (any colour you like)
  • 10x Piece of rope

Also, you will need an tool for the layout of the circuit and you will need an tool to make the . apk for your phone.

I used circuito.io for the layout of the circuit and Appinventor2 to make an easy prototype app for the android phone.
