First version of my stargate switch.
The IR sensor is active low. For exact pinout consult the datasheet (ie. sfh 5110), or play a bit, and test it with a TV remote.
To check IR led works, you can test it with a digital camera.
The switch detects hand at distace up to 10-15 cm.
My text is just fine :-P
