OK guys I hope you can help me on a little project which sounds simple, but has been quite complicated.
The Project
A simple timer which controls a solenoid.
Explanation
I need a timer that can be triggered by a start button, then after a set amount of time like 30-40 seconds, the circuit then triggers a solenoid for 5 seconds, then resets.
There is also a stop/reset button to stop the sequence if needed.
Also when the start button is pressed a buzzer and flashing LED would be activated, but these need to stop if the stop/reset button is pushed.
Oh and it needs to run off a 9v battery
Sounds simple......
Now I've looked on the web and have found plenty of diagrams and ideas using a 555 timer, some are adjustable, some are not. I have also seen some you tube videos, I can also buy one, but it needs 12V, which is not practicable.
I did find one circuit that may of helped, but I dont know is it would power the solenoid.
So I hope someone can help, the last time I done electronics was about 23 years ago when i was a school/college and never really followed it through.
I know its a big ask, but even a push in the right direction or a curcuit diagram and a list of parts would help, and I can then sort out the rest... Some how lol
Look forward to hearing some replys.
