Learn how to detect cosmic rays with this simple and cheap detector, built by Hacker in Residence Pete Marchetto.

How to hook the HMC6343 -- a high-end, tilt-compensated compass module -- up to an Arduino. Never get lost again!

This tutorial will show you how to combine a webcam, a 32x32 RGB LED panel, and a Teensy 3.1 to stream video from the webcam, pixelate it, and display it on the LED panel - LIVE.

Your guide to the Digital Sandbox! 16+ experiments that, using a graphical programming language, teach you to blink LEDs, monitor microphones, read temperature, and much more.

Let's take the same examples from the ArduBlock-based Digital Sandbox guide, and implement them using Arduino code.

We admit the Arduino IDE isn't for everyone. Here are some other options for programming your Arduino boards, including web interfaces and graphical programming languages.

Breakout of MS5803-14BA Pressure Sensor to measure the absolute pressure of the fluid around them to determine altitude, water depth, or any other tasks that require an accurate pressure reading. This includes air, water, and anything else that acts like a viscous fluid.
