How can I make a siren chime for a few seconds when a laser hits a photo resistor using a 555 timer chip? Answered
I am trying to make a target for my laser for camping trips. I don't know how to create my own arduino codes to program an ATtiny so I was hoping to create a monostable circuit using a 555 timer chip instead (If monostable is the correct circuit). Basically I have a 6-14V siren and want it to chime for at least a second when the laser beam hits a photoresistor during day or night. I have tried but to no avail, since I have not been able to understand the ways of the 555. Any suggestions with or without a 555 timer chip are completely welcome.
