Review on FTCBlock Infrared Obstacle Avoidance Arduino by Anferny Pineda

I used this product in an animal toy to synchronize the sound pattern with the breathing mechanism inside the toy. This part of the project was surprisingly easy to do - it only took a few seconds of setup before everything was working properly. The LED makes it easy to see how good the detection threshold is - not too short to get lots of false alarms, and not too long to get poor timing accuracy. The only downside is that it's bigger than it should be, which limits its use a bit.
