Asynchronous serial communication concepts: packets, signal levels, baud rates, UARTs and more!

An introduction to the concept of Pulse Width Modulation.

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

Using WiFi to send sensor data from an ESP32 to a WiFi network and be able to read it from an IoT Dashboard from anywhere in the world.

Equip your Arduino project with a sliding soft potentiometer to monitor position or adding linear control to your project.

Read humidity, pressure and luminosity quickly and easily. Add wind speed, direction and rain gauge for full weather station capabilities.

The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders.

Get started with the SparkFun analog MEMS microphone breakout board! In this tutorial, we will be connecting the differential MEMS microphone to an Arduino using the WM8960 audio codec.
