Hello everybody, I was working on an electronics project, and one of the LEDs (actually I'm using only one) started acting really strange! It will light up when I come close to it, ONLY if I have been out of the room for some time! And that's not all, the period for which it will light up is proportional to how much I have been away (i.e. the longer I stay far from it the longer it will light when I return) I was thinking of 2 possible explanations how this can happen, Explanation 1. When I get out of the room I somehow get electrically charged, and this creates an E-field around the led when I return, making it conductive. (But it will do this even if I go the other way (i.e. what matters is that I stay out of range, not where I go)) Explanation 2. The accidental sensor (be it capacitive or otherwise) is dependent on a capacitor that needs time to charge between "activations." But in this case it has a really wide range because I have to move 3~4 meters to get it to light again for a second or two! Any input on this is appreciated, thanks!
