Capacitors

A capacitor is almost like a small battery, it can be charged

using a power supply. Mostly used to stabilise or to filter out

unwanted voltages. The unit is Farad: practical values are

in µF, nF or pF. The supplied capacitor is an Electrolytic

capacitor 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 = + !

(Velleman part# L-7104LGD & L-7104LID)

Flat side, shortest lead = (-)

How to bend the leads:
