Step 3Wire the jack to the breadboard
This step is the messy one. Here we connect the jack to the bread board.
Basically, we are going to take power from the arduino and run it to the foot switch (via the black wire on my jack - i know i know i should have used a red wire). Then each wire off the jack we hook to a 1k ohm resistor. And from the back of each resistor, back to ground.
Then we need two generous wires to lead off the board from the front of each resistor (next to where the jack leads back in. These two wires we will use to test for HIGH/LOW on the Arduino.
