Hi I am working on a project to turn a light on when it gets dark (simply put it does do more ;)). The circuit is powered with a solar panel and battery. I just wanted to pass an idea I had by you guys. Normally I would use an LDR but thought that seeing as I have a solar panel I could use that instead (reducing component count and wire count lol).
I was thinking of using a blocking diode between the panel and the battery (both are low power) and picking the solar voltage off of the solar side of the diode:
SOLAR PANEL---------±--------->¦--------BATTERY (where the + is the point of detecting panel voltage and >¦ is the diode).
Anyone done this and do people think it would work?
