Previous Thread: Push Button Preset Timers
So I'm ready to start buying the pieces and want to make sure I have everything I need for this.
For a recap, the idea is 4 push buttons, each a preset timer (5 min, 15 min, 30 min, 1 hr) for a tactile, easy to use solution for my ADHD with no turning on the phone or changing settings to distract me.
The buttons I'm looking at are

I can set the red ones on the smaller timers since they are shorter and green for the longer timers.
I want a LED on the front showing bars representing the remaining time
I was told to use a 1602 display with a backpack
I'm told this should fit the bill for that
(Apparently only 2 links per post for some reason, so the product name on amazon is JANSANE 16x2 1602 LCD Display Screen Blue + IIC I2C Module Interface Adapter for Raspberry pi 2 Pack)
So I've got buttons and display, I was told to control I need an Arduino Nano, which I should be able to plug into a usb cord for power
For sake of buying all in one place, I'd like to get this on Amazon, but I'm not sure what to get as there are multipacks for $10 with an offbrand name, then a arduino brand single for $13 and another one called the nano every. Not sure what the difference is there. I need a good single pack that will work for this project. I've been told this will require soldering, which I can do with my dad, he has a soldering iron and I've used once or twice before. I can either relearn it or have him do it so not worried there. I do want to make sure if I need headers, what kind of wire I need, etc. This is all brand new to me, and I want to get all of it and not have to go back to amazon for another order and wait to get the last pieces.
Any advice is greatly appreciated. Once I have all the parts to me I'll do a full post building it and asking about the programming side. I just need the actual parts list ready now
