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

Every electrical project starts with a circuit. Don't know what a circuit is? We're here to help.

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.

An initial project using Alchitry's onboard FPGA to manipulate PWM

Breakout of MS5803-14BA Pressure Sensor to measure the absolute pressure of the fluid around them to determine altitude, water depth, or any other tasks that require an accurate pressure reading. This includes air, water, and anything else that acts like a viscous fluid.

It's now easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS726X spectral sensors allow you to detect wavelengths in the visible range (VIS) and near infrared range (NIR)!

The gator:environment combines two I2C sensors for temperature, humidity, pressure, eCO2, and eTVOC values. This tutorial will get you started using the gator:environment with the micro:bit platform.

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