So I am currently trying to make light operated alarm clock, and I already managed to get the most annoying noises possible using 2 piezo buzzers and 2 555 timers, but now I need the switch that would activate the alarm.
So here is where I am stuck.
How would I get a photoresistor to act as a switch without the use of microcontroller?
I need it in such a way that when it reaches certain light level, then electricity will pass, and if its dark then it does not output any electricity.
I did some research and found out I have to use PNP transistor, but I am still stumped and have no idea how to use it, please help me
Thanks to everyone in advance who helps
