Laser Detector On/Off Switch Controller

[Lepek88]

Is there anyway to add a speaker to this circuit? When the laser hits the photoresistor an alarm goes on.

Class circuit!!! i've one kinda similar (but much less advanced) built on my channel too!

That's very clever how you used the two sensors to balance the circuit. I'll have to try it sometime. Thanks for the vid.

Coool...

[salzahrah]

is their anyway that it could turn on/off a motor instead of a LED???

[wepef3D]

@salzahrah Ofcourse, but you should use the chip to control a relay which controls a motor (because the motor will most likely draw more power than the chip can supply)

[jkenn184]

@salzahrah Dude, it's just a switch. It should essentially be able to turn anything on or off. :)
