I’m stuggling to understand how to make a system diagram for this game I have to make for school. Basically I want a toggle switch to be an overall on off switch. A motor which turns on and off when the toggle switch does. I need the timer to start when the first reed switch turns off and it to stop when the second reed switch turns on. The timer should be displayed on a dual 7 segment display and when the second reed switch turns on the piezo sounder should turn on. This is what I’ve done so far but I have no idea where to go from here and I don’t have a clue if this even works image.jpg

Welcome to maker.pro!
I suggest you start by concentrating in turn on the two main items: (1) a timer which can be started with one switch and stopped with another and (2) something to convert a time value to a dual-digit display.

I usually use the 555 IC timer to make either an astable or monostable circuit but I’m not sure that it would be suitable for this circuit as as you said it would be useful if the timer would be able to be started by one switch and stopped by another and I’ve not been guided to look at any others

but I think arduino is basic but I don’t mind learning
Arduino will do what you want and much more..........just break each section down into working examples and then combine.
Just watch your approach to negative logic and fail safe as it will catch you out.(reeds)

Arduino is C/C++. There are also block languages which are fun for quick turn
one off projects. An example :

Another example how simple it is to do something like a talking voltmeter :


or a simple network design :


Once you learn a block language they all pretty much same.
