Hello everyone. I'm entering a competition and where I have to invent something that will improve the personal lives of people. Basically, I want to use Arduino to create a shopping basket that can scan items and pay using the basket, instead of waiting in line. My issue is, this will be the first time using Arduino (or any MC for the matter), so I need help creating a list of needed parts. I do know C++ pretty well though, so coding shouldn't be much of a hassle.
My budget is about $100 ish.
So far this is what I have:
- Arduino (what model?)
- Bar Code Scanner that can read UPC ($20)
- 20x4 LCD Screen ($10)
- 9V Battery Pack ($4)
- Soldering Iron ($17)
- Keypad for entering card info ($5)
Anything else needed? I feel like I'm missing some crucial equipment, but I'm not sure. Hardware isn't really my thing
