How to make touch switch using 2n2222
In this project we learn How to make touch switch using 2n2222 npn transistor easy at home easy step with circuit diagram.
in this project we use only one NPN transistor. for making this project we need some components.
|How to make touch switch using 2n2222|
|touch switch components|
- 2n2222 NPN Transistor (1)
- 220ohm Resistor (1)
- LED (1)
- 9V Battery
- Battery clip
- PCB Board
- Soldering wire
- Soldering iron
In this project we use single transistor 2n2222. and make it very easy circuit.
When we touch hand on touch point then LED on. And when we remove hand then LED off. It’s very simple homemade project with few steps.
we learn it more batter using video.
