LED Gumball Machine

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

A quick introduction to accelerometers, how they work, and why they're used.

Introducing fundamental digital logic concepts and LogicBlocks

This tutorial will show you how setup a simple peer-to-peer connection to send and receive sensor data between two ESP32 WiFi boards.

Review, teardown, and hacking tutorial for the MindWave Mobile, a $99 commercial grade EEG sensor.

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.

The MyoWare® 2.0 Muscle Sensor, an Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies. In this tutorial, we will go over the features and related shields to connect the sensor to a muscle group.

Getting started with the AMS dToF imagers (TMF8820 and TMF8820).
