LED Gumball Machine

The world is analog. Use analog to digital conversion to help digital devices interpret the world.

An overview of electric power, the rate of energy transfer. We'll talk definition of power, watts, equations, and power ratings. 1.21 gigawatts of tutorial fun!

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

An introduction to I2C, one of the main embedded communications protocols in use today.

SparkFun's ESP32 Environment Sensor Shield provides sensors and hookups for monitoring environmental conditions. This tutorial will show you how to connect your sensor suite to the Internet and post weather data online.

Monitor the weather without being exposed to it through wireless communication between two micro:bits using the radio blocks! This is useful if your weather station is installed in a location that is difficult to retrieve data from the OpenLog. We will also explore a few different ways to send and receive data.

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.
