Thanks for having a look at my instructable! If you have by chance seen my original clap-clap on/clap clap off circuit instructable. This clapper circuit is very different than my original, in that it requires absolutely no amplification of the audio signal being sampled by the on-board electret microphone! As well, the circuitry is powered exclusively by the USB port on my PC!
For all of you who find this instructable interesting, I would apprecaite your vote in the USB contest. As well, please rate this instructable. If you found it to be good, I want to know! If you found it needed work, I want to know! Thank you for your consideration!
I'll be creating a kit for this instructable within the next few weeks, but without the relay. It will be available here:
Here are some of the key features:
* By simply turning your computer on, you can clap-clap on anything powered by AC that is within the limit of the 5v relay you are using (A desk lamp for example - Seen in the below video)
* EXTREMELY LITTLE HARDWARE REQUIRED! Less than $10
* No amplifier circuitry required. The audio is sampled through the use of an ADC (Analog to Digital Converter), located on the MCU.
* Powered SAFELY by the USB port on your PC or laptop.
THIS VIDEO TALKS ABOUT THE PROJECT, GIVES YOU A DEMONSTRATION, AND TALKS ABOUT THE SCHEMATIC DIAGRAM!
