CIRCUIT DIAGRAM

Connect all the wires according to the diagram.

• Attach all-transistor to the breadboard
• Connect the Base pin of First Transistor to the Emitter pin of the second transistor.
• Similarly, connect the base of the 2^nd transistor to the emitter of the 3^rd transistor.
• Leave the base of the 3^rd transistor for further connections.
• Attach led to the breadboard
• Connect collector pin of 1^st transistor to the negative terminal of the led via a 220-ohm resistor
• Connect the positive terminal of the led to the positive rail on the breadboard.
• Connect collector pin of 2^nd transistor to the positive rail via 100k resistor
• Connect collector pin of 3^rd transistor to the positive rail via 1m resistor
• Connect a copper metal wire to the base of 3^rd transistor

OUTPUT

Connect the 9v Battery, Now touch the wire, you will see the led will light up.

And if you take away your hand from the led, the led will turn off.
