PIRfec'

This is a very small item and costs very little. I bought one for £2.54 and it's possible to buy a pack of ten from China for even less per item. Just check out eBay.
What is it? It's a very small PIR (infra red motion detector) that interfaces directly to an Arduino and can trigger an action. In this instance, I want it to turn on a couple of white LEDs for a short period.
