      Use an optocpoupler as a intermediate stage between the triac and the AVR. The command current shouldn't exceed 20mA, if it does, use a transistor or a repeating/ inverting gate.

      ... The MOC3041 _is_ such an optocoupler (LED Trigger Current: 15 mA). See http://www.fairchildsemi.com/ds/MO/MOC3041-M.pdf Do you want to switch the bulb

        The MOC3041 _is_ such an optocoupler (LED Trigger Current: 15 mA).
        See http://www.fairchildsemi.com/ds/MO/MOC3041-M.pdf

        Do you want to switch the bulb constantly or dim it by phase cutting ?
        The MOC3041 has a zero cross detection, which makes it a bad choice for
        a MiPro-driven dimmer. Use MOC3021 instead, if you want to trigger
        _between_ zero crossings for the rest of each half cycle period

        But if you just switch the optocoupler on and off for a longer period,
        it might also work with the MOC3041.

        Wolfgang

            From the diagram you uploaded I see you are having difficulty designing the circuit. There are a couple things you might try. First, do an internet search for "triac circuits". You will find many you can just copy. Second, you would need to do some study to learn the basics of electronic theory, and then you could design your own circuits. That may take too much time, so the first may well be your best option.

            The circuit you show us has some serious problems:
            1- The driver transistor is connected directly across VCC, so if (when) it turns on it will short out the power supply. = smoke!!
            2- The gate of the triac is connected directly to VCC, so will never see a switching action from the transitor.
            3-The LED in series with the transistor base may not allow the transister to turn on, depending on the transistor's base characteristics and the size of resistor you put in the circuit. Transistors are current controlled devices, so you would need to calculate the required base clurrent to drive the transistor into saturation, and then design the input cirucuit to provide that current.
            4- It would be wise to isolate the AC power from the DC circuit of the uController. =Less smoke!!

            You have an interesting project, I know there is information on the internet about precisely what your are trying to do, so a little searching will solve your problem.

                Ever, looks like a good circuit. Will the 3031 handle the 220VAC? The data sheet says max 250V peak, and 220VAC has a peak of ^300. Perhaps the 3041 would be a safer choice?? I have not built the circuit, so if you have done so and it works, then no problem.

                :O

                Use an optocpoupler as a intermediate stage between the triac and the AVR. The command current shouldn't exceed 20mA, if it does, use a transistor or a repeating/ inverting gate.

                Regards,
                Mihai G.
