Introduction: Counting With IR and LCD
Today i'll present a my old project, made between january and february of 2015. It's a simple counter, based on Atmega328p and IR sensor Sharp 2Y0A21.
Working with small automatic machines, during the stages of testing, I needed to count the pieces coming out. So I made this simple device. Powered with 9V battery and equipped with 8x2 lcd display, it's perfect for my needs, it's portable and reliable.
