13. Put a wire from the right side last hole of the integrated circuit to the left side first hole of the integrated circuit.
[[File:insertWire3.jpg|caption|none|800px]]
14. Put a wire from the third to the last hole next to the potentiometer to the third hole on the left of the integrated circuit (next to the capacitor and wire).
