In this instructable, we will build a motion detector and trigger IFTTT events from that device. You may create IFTTT recipes for receiving email if someone is inside the house or switching a Belkin WeMo when you walk into a room. As the motion detector cannot directly contact IFTTT, we will use Lithouse as the broker. You will need the following components: PIR Motion SensorArduino UNO R3Arduino
