I'm completely new to the platform, so bear with me.
I asked in another tech forum about this project and they suggested I use arduino, so time to get into this I guess. What I'm looking for is whatever guides I need to read or intros to use to create a very simple desktop timer. I am building the enclosure of wood, I know woodworking. And I want 4 mushroom style push buttons on top, one connected to each preset timer (5 min, 15 min, 30 min, 1 hr) that I can use in lieu of an egg timer or something on my phone. I have ADHD so distraction and ease of use is the name of the game. Alarms on my phone require too many button pushes, and there's no physical feedback so there's no emotional stress to turning it off, ignoring it or snoozing it. With egg timers, having to face my perfectionism and twist to the right spot every time I just end up not using it. So I need something with physical feedback, no way to ignore it, and very quick to use.
I have some buttons in mind I found online, no clue if this is good, but right shape and size
I would prefer metal top to these plastic but I seem to only find metal up to 22 mm and I need 30 mm, I have big hands. If anyone knows of a good metal mushroom top button 30mm that I can use, that would be awesome.
As far as programming, I want to press the button to start the timer, loud alarm goes off and press again to end timer or turn off alarm. If I can power with usb-a and plug it right into my pc, that would be great. I know conceptually what I want but I'm completely new to this and don't have a clue what I need to get there. Any help is greatly appreciated!
