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

just what i was looking for ... thanks.

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.

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

Bravo. Very easy to understand video. (and like the guy below said. nice looking board)

Thanks for the upload

@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)

wow, very oranized board. i love it.
