Easy to build, but comparable with professional seismometers, homemade Arduino seismometer.

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

In this tutorial I am going to show you how to build a Wireless Weather Station with a big 3.2" Color TFT display using Arduino.
