All-in-one fingerprint sensors make ID easy.

In this guide we will create a simple knob sketcher toy using a graphical display and two potentiometers.

Combining a simple external circuit with the Raspberry Pi to create a simple door-locking mechanism that takes advantage of the speech recognition library.

How to use Charlieplex LED matrices with CircuitPython!

This tutorial will explore how to port an Arduino driver for the VL6180X distance sensor to CircuitPython.

An expensive liquid crystal display is not necessary for displaying data in most applications instead a seven-segment display is simply sufficient.

In this project, you will be building an object detection DC motor controller.

You can connect Arduino sensors, actuators, and other ICs with the digital inputs and outputs (digital I/O) on the Arduino for useful things, such as reading switch inputs, lighting indicators, and controlling relay outputs.

It's easy to make a digital voltmeter with an Arduino and a 16x2 liquid crystal display (LCD). This project will also help you measure voltages above the reference voltage using a voltage divider.

This module allows you to do basic drawing like putting pixels and filling rectangles on TFT displays like the TFT FeatherWing.
