    Hi,

    I am devloping product smilar to coffee maker.That also use relay to on time/off time relay.Please suggest me what kind of microcontroller best suitable for this appliance.

    Thank you.

    Regards,

    Ragin

    A digital one.

    Seriously, there are about a bazzillion different microcontrollers and you've given so little information that it's impossible to make anything but the most banal observation.

    Hi Steve,

    Please refer the attached circuit diagram for more detail.

    Thanks!

    Funny, I don't see any microcontroller in your diagram, so I guess any one is as good as any other.

    Some Attiny will do the job, but also a NE555, RC + OpAmp, etc.

    There are a lot more solutions to this problems that don't reqire a µC at all!

    If you're going to use a microcontroller or any sort of digital circuitry to switch relays, you can't pull enough current from the microcontroller itself so you're going to need a transistor for each of the relays. Also, you'll need an AC to DC power converter to get DC power for energizing the relay coils.

    Not true, there are plenty of relays that are fully switchable with the current from microcontrollers.

    Thanks, that's good to know. I've only looked at ATtiny and a PIC16 so my knowledge on microcontroller specs in general is limited. Less parts definitely makes a device easier to troubleshoot :)
