Genie chip timer

[Electroclueless]

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

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.

Great! Any suggestions of what i could use ?

Since this is your schoolwork, what research have you done for timing circuits?

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

Do you know how to Arduino code ?

I know a bit of python 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 :

Pulse Sequence Generator / Smart Timer

Often users, developers, hobbyists need timed and qualified event generators, many resorting to 555 timers and the like. The venerable 555 has had a long run but its limited in accuracy and capability. This approach uses block language to create...

I’ll definitely look into that thanks so much !!

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

GUI Codeless Processor Design

Micro design has for years relied on ASM and C programming and other languages. Often many tasks are fairly simply but these tools were focused and quite a learning curve, especially ASM and C and C++. There are a number of new GUI based tools that essentially take out the "strong typing"...

or a simple network design :

Verizon Remote Hotspot Controller

Had a problem with a remote site, property management. Basically wanted to run Network on site with a Cell based solution. Key issues : 1) Hotspot, if it lost power and ran batteries completely down would not boot all the way into Cell tower connection. It would charge on power return (its...

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