OPTO Switch Winder

Uncategorized, , , , ,
Arduino Counter for Pickup Winder 2.0 with OPTO Interrupter Switch. In this video I show how I am using an Arduino to count rotations on a motor by using an Ardunio Nano a TM1637 Display and an OPTO Interrupter switch. Ill be using this setup to build a counter for a pickup winder but it can be used for many other purposes. Hope you enjoy.
