The Problem

At Adafruit, we have a tester for virtually every product we manufacture. With hundreds of fab-made products in our catalog, that’s a lot of testers! When a tester has finished its job and there are no more boards to test, for the time being, it needs to go back home to the tester library. When the bin gets too full, I empty it and return the testers home after their long adventure. Sometimes, I forget to check the bin, and all of the sudden, the bin is brimming with testers.

The Solution

What if I could have someone else (like a robot) keep track of the testers and tell me when the bin is full? That’s exactly what this project will do. Using a FunHouse and an IR (infra-red) sensor, The project will track each time a tester gets placed in the bin with WipperSnapper and AdafruitIO. From there, a service called IFTTT will count the testers and send me an email when the bin has nearly reached its capacity.

While this is a specific project from the Adafruit factory, the method used to count actions is applicable to many aspects of everyday life such as filling a laundry bin.

Prerequisite Guide:

WipperSnapper is an interface for Adafruit IO, Adafruit's incredibly easy-to-use IoT platform, designed to turn any WiFi-capable board into an IoT device without programming a single line of code.
