A quick introduction to pull-up resistors - whey they're important, and how/when to use them.

This tutorial covers the concept of analog and digital signals, as they relate to electronics.

Introducing fundamental digital logic concepts and LogicBlocks

What is an interrupt? In a nutshell, there is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt. There are two types of interrupts: hardware and software interrupts. For the purposes of this tutorial, we will focus on hardware interrupts.

Get started with the MAG3110 3-Axis Magnetometer and learn how to make your own digital compass that senses the Earth's magnetic fields.

A quick hookup guide and project to get you started with the Soil Moisture Sensor from SparkFun.

The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.

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.
