Circuit Monday # 7 Touch Switch

Good afternoon folks and welcome to another Circuit Monday todays circuit is Touch switch

Components needed 

all my Circuits are breadboarded on the prototype board I made here 

1. a npn transistor 
2. a led 
3. a resistor 
4. jumper wires 

Uses for this circuit 

You can use this circuit for to make a touch light or an electronic bell and a number of other projects 

Step one 

the first step is to place the transistor in the broad 

Step two

the next step is to connect the emitter pin of the transistor the negative rail of the broad with a jumper wire 

Step three

then connect the resistor to the collector of transistor  then to an unused row on the board 

Step four

then connect the cathode of the led to the resistor and then the anode to the positive rail of the board 

Step five

the last step is to connect a jumper wire to the base of the transistor and to the positive rail of the board these are the probes
