Light is a useful tool for the electrical engineer. Understanding how light relates to electronics is a fundamental skill for many projects.

An introduction to polarity in electronic components. Discover what polarity is, which parts have it, and how to identify it.

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

Learn the options for powering your LilyPad projects, LiPo battery safety and care, and how to calculate and consider power constraints on your projects.

Get up and running with the MPU-9250 9-axis MEMS sensor.

The Melexis MLX90640 contains a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. In this guide, we’ll go over how to connect your Qwiic Infrared Array with MLX90640 and get it communicating with Processing to produce a nice thermal image.

The SparkFun Qwiic Proximity Sensor is a great, qualitative proximity (up to 20 cm) and light sensor. This hookup guide covers a few examples to retrieve basic sensor readings.

This guide covers the general design of the board, the installation of the recommended software used to program the Artemis DK, and some basic examples. For more advanced functionalities, we have separate software development guides for the AmbiqSDK, Arm® Mbed™ OS, and the Arduino IDE platforms that users can reference.
