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.

The main advantage of this sensor over standard MEMS Acceleration Sensors is in its ability to distinguish between actual seismic activity due to an earthquake and signals due to other causes.

Learn how how to build a water level indicator that triggers an LED and a buzzer.

Explore how to build a Morse code translator using Arduino and a 7-segment display.

In this tutorial, we will learn about how to create a theatrical prop for a performance by 3D printing a wand and adding an LED.

Explore the challenges faced and the solutions found, including the creation of efficient salt bridges and the choice of materials for electrochemical cells.

Explore the second part of our robotics education series as we delve into detector calibration, LED indicator integration, and student-led debugging efforts.

The SparkFun Audio Codec Breakout - WM8960 is a low power, high quality stereo codec with 1W Stereo Class D speaker drivers and headphone drivers.

Lithium-Ion Polymer (LiPo) batteries are a favorite of ours. Very light weight and some of the highest energy densities available.

In this project, we’ll create a wearable LED Crystal Crown using a simple circuit made of 7x Super Bright White LEDs wired in parallel and powered by two coin cell batteries wired in series.

The SparkFun Adjustable LiPo Charger is a single-cell lithium polymer (LiPo) and lithium ion battery charger.
