Musical Table

Step 2 Wiring the Table

Make four sets of three 1k pull down resistors that connects Arduino pins (pin 2 – pin 13) to ground. Use different colors of wires for each set to distinguish the groups easily.

1. Base1connection:  Connects to digital pin 13, 12, and 11 to a breadboard. Add another wire next to pin 13 on the breadboard, and connect it to the power.
2. Add pull down resistor (a resistor that connects to ground) between each pin and ground.
3. Base2 connection: Leave some space on the board and connect digital pin 10, 9, and 8 to the circuit board and power in the same way as step 1 and step 2.
4. Base3 connection: Take the second Arduino board and connect digital pin 7, 6, and 5 to the same breadboard.
5. Add pull down resistor between  pins (digital pin 7, 6, and 5) and ground.
6. Add another wire next to pin 7 that connects to power.
7. Base 4 connection: Leave some space below base 3 connection on the board and connect digital pin 4, 3, and 2 to the circuit board and power in the same way as step 4, 5 and 6, except this time the power is connected to a wire next to pin 4.
