In class, we have done a Pimp your Pumpkin project. Me and my partner, Ryan, used an Arduino and PIR sensor. The PIR Sensor detects heat moving. When a person makes movement they PIR sensor detects them and makes the LED light up. The Pumpkin then looks like it had a candle because of the orange light in it. This is a very cool seasonal project that I am excited to see Trick or Treaters reaction to it.
