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

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

Every electrical project starts with a circuit. Don't know what a circuit is? We're here to help.

Learn how to use conductive thread with LilyPad components.

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!

Learn how to use the SparkFun Photon IMU Shield for your Photon device which houses an on-board LSM9DS1 system-in-a-chip that houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer.

How to hook up the LilyPad Light Sensor as well as some project ideas and example code.

Magnetically-actuated reed switches are the perfect component for non-contact proximity sensors. This tutorial provides a quick overview and example hook up.
