Build a smart "Clapper" with SmartThings and Arduino

When my colleague @thegibertchan first set up his homemade “Clapper” in our office, I knew immediately that I had to learn how it was made. [image] The way it works is simple. A small microphone listens to two claps (within four seconds of each other) and it triggers a switch to turn on or off. Gilbert even simplified the code so it uses the built-in LED in the our SmartThings Arduino Shield. [image] I will try to explain how to build it here. You’ll need the following items: 1 Arduino Uno board ($24.95) 1 tiny breadboard ($4) 1 SmartThings ThingsShield ($35) 1 microphone amplifier ($6.95) 3 jumper wires ($0.50) 1 smart outlet ($55) Maybe the actual Clapper is less expensive, but this one is definitely mor…
