Help with Clap on light switch, ATTiny85

gub11

This is my first post on this forum, and im also really new to arduinos and have very little electrical experience, so please explain thoroughly, thanks.

I looked at some designs for clap on clap off light switches, but i didn't want to use a breadboard, to save space, so i made my own design, which i will attach below, I just had a few questions.

First off, does it look good? (not estethically of course lol it looks like ***, but I mean does it look like it will work)

also, the relay on the right side of the circuit, I don't know really how relays work, so if somebody could explain what to do when i get there in the design, because right now i just drew it in, I don't know what to do.  I also read that relay's were very taxing on the battery, so is there another option?

Thanks a lot

    Bits of that circuit might work with some good coding, but basically it won't be easy like this, nor can the relay be directly connected without additional circuitry anyway.

    However, clap circuits are popular enough that you'll find some detailed explanations in many places. Try this project (PDF link): http://www.epemag.com/lib/free_projects/home/0600%20-%20Automatic%20Night%20Light.pdf

    The circuit there drives a lamp, but you can replace the lamp with a relay directly.

    Also if you want to do fancy stuff like switch on/off toggled via hand clap or some other clapping scheme (e.g. three claps to switch off), then you can make a cut between pin 3 of that IC in that circuit in the PDF and resistor R5, and insert your ATtiny chip there, as long as you power things at 5V or so.

    Anyway, in summary, there are no easy shortcuts to learning - the best approach is to take a known working circuit and build on it, rather than connect an ATtiny to a microphone and to a relay directly. They are not directly compatible, even with the resistors and capacitor in your circuit.

    EPE is a fairly reputable magazine so the PDF will have an established, known working circuit. The last thing you need when you have little practical experience is an untested design.
