Connect power and ground to both sides of the breadboard. Place the pushbutton on the breadboard and connect one end to the 5V. On the other side of the switch, connect to ground through a 10-kilohm resistor. Connect this junction to digital pin 7 on the Arduino.

Next step is to attach your piezo, first attach the wires from the piezo to the breadboard. Attach one wire to power and wire the other end of the piezo to Analog pin 0(A0). Place a 1-megaohm resistor between the ground and the other wire. Lower resistor values will make the piezo less sensitive to vibrations.

Wire up the LEDs, connecting the cathodes (short leg) to ground and placing a 220-ohm resistor in series with the anodes. Through their respective resistors, connect the red LED to Arduino digital pin 2, the yellow LED to digital pin 3, and the green pin to digital pin 4.

Insert the male headers into the 3 or 4 female sockets on the servo motor and the fans(see figure above for fan pin instructions). For the servo connect the red wire to power, and the black wire to ground. Place a 100uF electrolytic capacitor across power and ground to smooth out any irregularities in voltage. Connect the servo's data wire to pin 9 on your Arduino. Repeat this procedure for each of the 2 fans connecting the data wire of one to pin 10 and the other to pin 11.

Place the TMP26 on the breadboard with the rounded part facing away from the Arduino(the order of the pins is important!). Connect the left pin of the flat facing side to power, and the right pin to ground. Connect the center pin to Analog pin 1(A1).
