LED Gumball Machine

A quick introduction to pull-up resistors - whey they're important, and how/when to use them.

The AST CAN485 is a miniature Arduino in the compact form factor of the ProMini. In addition to all the usual features it has on-board CAN and RS485 ports enabling quick and easy interfacing to a multitude of industrial devices.

LTspice is a high performance SPICE simulator, schematic capture and waveform viewer with an impressive library of passive devices. Over 1000 models are included in the download but you can also add third party models.

Protect your project by adding a fuse in your circuit to save it from molten destruction.

Get started with the SparkFun analog MEMS microphone breakout board with Arduino! Create a volume unit meter with the ADMP401 or ICS-40180 to react to sound before building your sound visualizer!

Control LEDs based on your movement using an accelerometer! Make your LEDs breathe by fading in and out when laying on the floor, turn off the LEDs when moving to your side, or make the LEDs blink in a headstand!

Are you worried about the looming clouds in the distance, how far away is that storm exactly? Add lightning detection with the AS3935 to your next weather station or your next bike ride!
