Introduction: How to Make a Dimmer Switch
In this instructables I will show you how to make a dimmer switch
Step 1: Components Needed
1)bt136 triac
2)2× 220k/400v capacitor
3)224j/400v capacitor
4)33ohm resistor
5)2× 68k resistor
6)8k2 resistor
7)diac
8)100k volume control
9) dot board
Step 2: Circuit Diagram
Step 3: Final Procedure
Now we need a project enclosure I make a hole for volume control and a hole for cord wire finally need a 3pin plug and close your box make sure there is no short circuit in the box insulate all wire.
Step 4: Final Result
Now our project is complete you can control brightness of incandescent lamps and speed control of ac motor finally the temperature of soldering iron.
