SPI is commonly used to connect microcontrollers to peripherals such as sensors, shift registers, and SD cards.

This tutorial covers the concept of analog and digital signals, as they relate to electronics.

A primer on digital logic concepts in hardware and software.

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.

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