Learn about Ohm's Law, one of the most fundamental equations in all electrical engineering.

LTspice is a high performance SPICE simulator, schematic capture and waveform viewer with an impressive library of passive devices. Over 1000 models are included in the download but you can also add third party models.

Use RealVNC to connect to your Raspberry Pi to control the graphical desktop remotely across the network.

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

The SparkFun ESP8266 Thing Dev Board is a powerful development platform that lets you connect your hardware projects to the Internet. In this guide, we show you how to combine some simple components to remotely log temperature data, send yourself texts and control lights from afar.

The goal of this project is to have a website hosted on an ESP32 that controls any relay controlled device connected to a local network and keeps a dynamically updated state of those devices.

A hookup guide to get started with the BME68x Environmental Sensor from Bosch. Monitor the air quality, temperature, humidity, and barometric pressure with this Qwiic sensor!

Get started with the SGP40, BME280, VCNL4040, and microOLED via I2C using the Qwiic system and Python on a Raspberry Pi! Measure VOC Index, light, temperature, humidity, and pressure from the environment. Then display them on the microOLED, serial terminal, or the cloud with Cayenne!
