## Overview

Here's another take on the [electronic animated eye project](../../../../animated-electronic-eyes-using-teensy-3-1/overview) by [Phillip Burgess](../../../../users/pburgess). Inspired by Sheb Wooley's 1958 hit novelty song, we present our _one-eyed, one-horned, flying purple people eater…_

Like the [bowler hat project](../../../../animated-electronic-eyes-using-teensy-3-1/bowler-hat), this one uses a _single eye,_ making it more affordable and easier to build than its two-eyed brethren. It can also be installed as a functional doorbell, _perfect_ for Halloween!

## YOU MUSTN'T CROSS THE STREAMS!

This project uses **two push buttons,** one triggers the eye blinking, and the other rings the doorbell. The wiring should never be crossed/mixed up. Doorbells are typically higher-voltage (10 to 20V) alternating current and will totally blue-smoke the electronics, if triggered by a single button.
