IR leds, the PING sensor and resistors
February 15, 2010
As an absolute beginner in electronics I was wondering about a few things. Will IR proximity sensors be affected by IR LED lamps? This because I am thinking about adding one to the lazybee (just for playing arround with it) but I would also like to have some IR led's for nightvision (the cam can see IR light).
I already ordered the Ping sensor but where can I mount it on the bot? For example, can I mount it 5cm from the edge of the bot or would that make it "see" an object (the bot itself in this case). Or can I mount it on a little pole so it looks "over" the bot. I'll probably mount it to the front anyway but was just wondering how the signal spreads and returns.
On the resistors, I got a few and one of them has a bit of the colormarkings and covering missing (like a small piece of clay that came off). Can I still use that or is it destroyed?
