Hi.
I remember seeing a thread quite a while ago about how to make a sensor to detect a heartbeat. I've search the forums but come up emtpy. Can someone else find it? Or does anyone know how to get a PICAXE to read a human pulse?
I vaguely recall something about detecting red LED light through a finger.
