I'm new just joined tonight . I had an idea for a circuit for this project I'm doing and I was just wondering if it would work and is the best way to do so.
I was planning on having an LDR circuit which - when it was dark - would trigger a 555 timer in monostable operation to then trigger a 555 timer which was in astable operation?
I'd be needing the astable 555 timer to turn on for roughly 2 seconds, off for 16 seconds, then back on for 2 seconds then just switch off permanently. So I was hoping to do this by having the monostable 555 timer turn on for around 20 seconds. Is there an easier way to carry out this and would it work??
Ahh I haven't actually chosen that yet, I was planning on going into my labs tomorrow to check what all was available. It was pretty much a rough idea and I was just checking whether it would be worth going ahead with it as I've quite pressed for time to complete it. I used a 555 timer calculator to figure out that I'd need the following value components.
