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

Generates maps based on distance between itself and obstacles autonomously and provides visual feedback.

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!

Use the DHT Temperature Sensors in C# code via a C++ Windows Runtime Component to implement a one-wire protocol on Windows 10 and the RPI2.

Take readings from the DHT11 Temperature/Humidity sensor and see them from the Arduino IDE Serial Monitor.

Did you know that a standard three-wire PC Fan can be used as a sensor?
