I want to change this code from attiny13 to arduino uno

this code for dimmer

The pin change interrupt registers in the Atmega328 have other names than in the Attiny13

When you change this:

PCMSK |= (1<<PCINT0);// pin change mask
GIMSK |= (1<<PCIE);  // enable PCINT interrupt

Into this:

PCMSK0 |= (1<<PCINT0);  // pin change mask
PCICR  |= (1<<PCIE0);    // enable PCINT interrupt

It will compile, but you will have to figure out finding and setting the pins correct yourself. I have no time to do that for you.

1. RV2 is your Dimmer -- Correct?

2. You roatate the Pot RV4; as a result, the brightness of your Dimmer channges; correct?

3. Now, briefly describe the working principle of the circuit that you have posted in post #1.

4. How much is V1 -- is it 110V or 220V?

5. How have you drived 5V supply for your ATtiny13?

6. Is everything in the 110V/220V domain or is there any isolation?
