5 WAY AC FLASHER
We use these types of circuits in most ceremonies (wesak festival, christmas, wedding, …). This 5 WAY AC FLASHER circuit running system base on cd4017 ic, timer base on ne555, output base on the component called “Triac” and power supply base on the capacitor. we don’t use steps down transformer and can be given directly 230V to this circuit .

BT138 PIN CONFIGURATION
5 WAY AC FLASHER NOTE:
Use heat sink when more lights are switched on by the triac.
Mica sheets use between Triac and heat sink when using a single heat sink
use mylar type 0.68µF 400V capacitor to the power supply (C1) .
Don’t touch any component, when circuit is connected to the 230V AC power.
Please send your ideas, those are very important for our success…
