- Complete all wiring connections as indicated in the sequence.
- Switch on the main switch. It appears that nothing happens. Actually the capacitor is being charged.
- After 1 to 2 seconds, switch off the main switch. The capacitor is charged and is storing a small amount
of electricity.
- Press the push switch. The electricity stored in the capacitor will be released immediately and the LED
will light up for a brief moment!

- Complete all wiring connections as indicated in the sequence.
- Switch on the main switch. The red LED will light up. Current flowing via the diode will charge the
capacitor at the same time.
- When you press the push switch, the yellow LED will light up. Release the push switch so that the
yellow LED will be turned off.
- Now switch off the main switch. The red LED will extinguish. If you press the push switch at this time,
the yellow LED will light up for a brief moment due to the release of the stored electrical charge of the
capacitor. However the red LED will not light up at all because the diode has blocked the current from the
capacitor which is in an opposite direction.

- Complete all wiring connections as indicated in the sequence.
- If you only switch on the main switch, or only press the push switch, the LED will not light up.
- If you switch on the main switch AND press the push switch together, then LED will light up.
- This is known as "AND Gate". Both switches have to be switched on in order to activate the LED.
