Hello:
I am a newbie when it comes to all things Arduino and was wondering if something like this was possible and what the difficulty factor may be. Here is what I am trying to do:
I want to have 150 individual LED lights spaced about 2 inches apart. A barcode scanner would scan the number 1 and LED number 1 would light up. Scan number 2 and LED number 2 would light up, etc.
Is something like this possible with Arduino?
Thank you!
I can't help you with the barcode reader beyond telling you it's definitely possible to make one with Arduino. You would just get the number value and use that to determine what LED to turn on. Wiring 150 LEDs sounds like a pain so I'd recommend an Addressable strip. For example: Pololu - Addressable RGB 150-LED Strip, 5V, 5m (WS2812B) There are WAY cheaper options if you Google some but that's a good example of how to use them and they provide test code as well. I'm also a newbie so take that with a grain of salt but hope it may help some!
