The next component we will be installing is the yellow capacitor. Capacitors store electrical charge, and are helpful when a circuit needs a quick shot of energy to illuminate a light or make a beep.

Capacitors are measured (in Farads) as the ratio of the electrical charge on each conductor to the potential difference between them. This capacitor is a 1 µF capacitor.

Install the capacitor in the terminal next to the IC socket marked C1. Soldering the leads of a capacitor follows the same through-hole procedure used thus far.

Make sure that the printed markings on the capacitor face away from the IC socket so that you can still read it.
