I'm building a nightlight that uses two blue cree LED's I want it to turn on and off at dawn/dusk..
Anyways i was looking on my scope and I'm using a LM339 and on pin 6 where the LDR is connected with light on the LDR I'm seeing 12 V and in a dark room it's about 1.2V or so..
Does that sound right? It's not giving me anything on the output.
