Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor.  The GPD12 senses objects at a distance of 10-80cm, while the 2Y0A02 has twice the range.

We’ve previously looked at the Sharp GP2Y0D02 digital proximity sensor. It only signals the presence of objects, while the GP2D12 and 2Y0A02 measure distance to them. If you’ve got a GP2YoD02, it might still be possible to tap the analog output. We’ll show you how use these sensors below.

We’ve had this same hack submitted by two people, pointing to two different(translated) sources(translated) today.

When we showed you Bar2d2, the bar tending party bot, there was one huge hurdle left to solve. It was only a drink dispenser at that, while awesome, couldn’t actually mix drinks. That has been remedied in this update. Now, a computer handles all of the drink orders, then sends them via bluetooth to bar2d2. The drinks are mixed right there in front of you in the comforting blue glow of bar2d2’s neon. You can check out more build pictures here.
