Turn a large voltage into a smaller one with voltage dividers. This tutorial covers: what a voltage divider circuit looks like and how it is used in the real 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!

An overview of the different protocols that can be used for the development of Internet of Things (IoT)-based projects.

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.

This tutorial will show you how to make a scale that logs your weight to a custom website on the Internet. The principles can be extrapolated to any type of data.

The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders.

Put together your Rotary Dial Kit and light it up with our Arduino example code!
