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

This tutorial will explain how to use and convert between the standard metric prefixes.

An introduction to I2C, one of the main embedded communications protocols in use today.

Learn how to use serial I2C and SPI buses on your Raspberry Pi using the wiringPi I/O library for C/C++ and spidev/smbus for Python.

A basic hookup guide for getting started with the SparkFun Wake-on-Shake. The board gives you the ability to put your project into hibernation until bumped or shaken awake using the ADXL362 accelerometer. This means you can design projects meant to stay inert for long periods of time, possibly even several years, depending on the battery type used to power the project.

Getting started guide for the Avago APDS-9960 color, proximity, and gesture sensor.

Build a portable gas monitor to check for dangerous levels of hazardous gases.

How to use and re-program the OpenLog Artemis, an open source datalogger. The OLA comes preprogrammed to automatically log data. The OLA can also record serial data, analog voltages, or readings from external Qwiic-enabled I2C devices. Some of these Qwiic-enabled devices include GPS/GNSS modules, pressure, altitude, humidity, temperature, air quality, environment, distance, and weight sensors.
