DIY Hacks & How To’s: Proximity Sensors

DIY Hacks & How To’s: Proximity Sensors

Last week I showed how to use a pressure plate switch to activate special effects. This week, I am going to show you how to make a simple proximity sensor. This is basically just an infrared LED and a phototransistor. When a person stands near the sensor, some of the light from the LED is reflected back to the detector. The output signal of the detector can be monitored by an Arduino and used to activate special effects when the person is close enough.
