Guitar Hero can either be powered from three AA bateries in series or by powering the Arduino nano with a mini usb cable.
- Step 1: Daisy chain one side of each Momentary push button with a ground cable coming from the Arduino Nano. The buttons are chained so there does not have to be multiple ground wires going to each button. Afterward, solder a wire from the other side of each button to the corresponding pin on the Arduino. The default for the first five buttons are pins 8-12 on the Arduino.
- Step 2: Solder the ground wire of the battery pack to the ground pin on the Arduino. The power wire from the battery pack is soldered to a 2 amp switch to turn on the game. Solder from the switch to the VIN pin of the Arduino Nano
- Step 3: Daisy chain the LED 5v inputs together and solder a wire from the 5V pin of the Nano. Then, daisy chain the negatives together and solder to ground pin.
- Step 4: Solder the corresponding data pin wires from the LEDs to pins 2-6 on the Arduino
- Step 5: Connect the speaker by soldering a wire from the ground pin to the negative on the speaker. Wire from pin 13 on the Nano to a side of the 3-pin potentiometer to control the volume. From the potentiometer, connect a wire to the positive of the 8 ohm speaker
- Step 6: Connect one side of a potentiometer to the ground pin and the other side to 5v on the Arduino. The middle pin will read the data and will be sent through a wire from the middle pin of the potentiometer to the Arduino A0 pin for reading.
