Capacitors
A capacitor is almost like a small battery, it can be charged
using a power supply. Mostly used to stabilise or to lter out
unwanted voltages. The unit is Farad: practical values are in
µF, nF or pF. The supplied capacitor is an Electrolytic capaci-
tor of 10µF and has a polarity, the long lead = +

Green & red LED
A LED is a Light Emitting Diode, it can
emit light using a small current (max
20mA with a 1.8V drop).
Watch the polarity, long lead = + !
