The customized clap on - clap off module
Programmable single or double clap
This listing is for a hardware programmable single or double clap on/off relay driver module that comes assembled and fully tested. The video above offers a complete demonstration relative to how this device works. Upon power up, the device scans the logic on the three pin header. The three pins header pins are labelled 1, 2, and 3. If you short pins 1/2 with the 2-pin header connector and power the device up, you will enter into double clap mode; meaning that it will take two claps in succession to toggle the relay on, and another two claps in succession to turn it off. If you power the device on with header pins 2/3 shorted, you will start in single clap mode, which only requires a single clap to activate the relay, and another to turn it off. There is a red LED indicator on board that lets you know when the relay is turned on. The above video will give you a full demonstration. I sell these in DIY kit form for a few dollars less, so check out our store! This device requires 7-9v @ 100mA or higher in order to operate. 9v is nominal. The relay pins are connected to a 3-pin terminal block.
These pins are labelled:
NC - Normally Connected to the Common Pin
CO - Common Pin (Connected to the NC pin when the relay is off / Connected to the NO pin when the relay has been activated)
NO - Normally Open. This pin is not connected to the Common Pin until the relay is activated.
Requirements:
1) A 7v - 9v power supply (If you're going to use a wall wart, aim for a 7v-9v. No more than 10v. 100mA or higher)
