I have as project at work to create a « counting box ». People in my team are counting daily small pieces (5 cm x 2 cm x 1 cm), in plastic, 1 by 1. For them to make their life easier (and increase our accuracy), i would like to create a small box where they could throw the pieces inside, and it would count them.
On this box, i would like 5 electonic parts : - a PIR motion sensor (as the parts a really small, i don’t want to have a laser only taking in consideration 1 direction but more a surface) - a display (big and simple), where it would be possible to count from 0 to 100 (no lore info is needed, therefore a lcd screen is not mandatory - a button « reset » (to put back to counter to 0) - a button + (to manually increase the counter of 1) - a button - (to manually decrease the counter of 1) I bought a Arduino nano, i think totally enough to perform the job.
I found a lot of videos taking about it in internet, but none of them are fulfilling my requirements. Like this one : https://youtu.be/WSDeNvYDZOw
Would anybody have information to help me ? Thank you
