Hey, everyone. I'm VERY new to electronics (trying to teach myself still), so bear with me here if what I'm asking seems really simple. I'm working on a project that involves a light/dark-activated switch and I need some help...
I have a solenoid that takes 24v to activate, and I want it to activate when a laser beam (from a laser pointer) is broken. I know that I'll need a photocell to act as a switch, but I'm not really sure what else. I've searched the forums and Google, but I haven't really come across what I need. Maybe I'm not searching for the right things though.
My power source is 24v, so I really just need to design a "switch" circuit to activate the solenoid when the laser beam is broken. Can any of you help me out? Maybe point me towards a schematic that you already know of?
Here are the specs on the photocell that I have:
Make: Archer
Type: Cadmium Sulfide
Max Voltage: 200v
Resistance at 10 Lux: 15 Kohms
Typical Resistance 100 Lux: 3 Kohms
Resistance Dark Minimum (1 minute): 0.5 Megohms
Thanks in advance!
