Hi..
as shown below, i am following this design and using Atmaga8 to control load using triac BTA16 which is not a logic level triac, therefor i am unable to fully switch on my triac. i dont want to use optocoupler because
1. my circuit uses transformer less power supply therefor isolation do not make sense.
2. cost (anyway...just wanted to add a point, 2 is better than 1).
My transformer less power supply can give a max of 70mA, and i need to run 3 triacs, I have 10 BTA16 in hand. What can i do. Can we device something like a mosfet driver using general purpose transistors to run the triacs gate from 220VAC .
