Introduction: Tab-Switcher

Tab-Switcher can switch tabs with a push of a button, don't need to drag the mouse to click or scroll your hands on the touchpad to switch tabs anymore, make your own Tab-Switcher, it's easy and simple.


For making the Tab-Switcher you will need:


  • 1 Breadboard
  • 1 Arduino board (I'm using Arduino Leonardo)
  • 1 Button
  • 4 Circuit wires
  • 1 Precision resistance
  • USB cable (connect your board to your laptop)


  • Any kind of box is ok, as long as you can fit your board in
  • Paint (if you want to paint the outside box)
  • Scissors or a cutter

Step 1: Circuits

  1. Connect GND and Pin 4 together
  2. Connect 5V to the button
  3. Connect Pin 8 to the button
  4. Connect the precision resistance to the same line of the Pin 8 wire
  5. Connect GND to the other end of the precision resistance

Step 2: Code

Step 3: Out-box

Place your board inside the box, make sure to cut two holes or squares for the USB cable and the button.

And you're done !!
