Like the bowler hat project, 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!
We recommend following the guides below to get familiar with the components used in this project.
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.
