Step 3Connecting the circuit to your mouse
It's time to connect your pushbutton - at pin 3 of the 555 - to the circuit board of your mouse.
Disassemble your mouse so you have access to both sides of the circuit board.
First, you need to follow the path on the circuit board to determine on which side of the switch to solder your pushbutton. You want the side that leads back to the mouse's microcontroller, since we will be feeding 5V pulses into it. If you use the side that leads back to the +5V supply on the mouse, your mod will not work.
Use your wire to connect the switch.
At this point, you can insert the 555, plug in your mouse, and test to see if everything's working the way it should.
