We’ve now updated our HCMAX7219 led driver library to support serial dot matrix displays such as our dot matrix module shown in the above image. The library supports

The MAX7219 LED driver is a handy IC for when you want to drive multiple LED’s. Although your Arduino may have plenty of digital IO pins for most

How to get started with our serial seven segment display module and make a cool scrolling display.   This 8 Digit Seven Segment Display Module takes advantage of

So you’ve taken the plunge… You’ve decided to buy yourself an Arduino development board. You’ve figured out how to get the development environment installed and you’ve even managed to

One of the things the Arduino environment does very well is to provide a quick and easy path into the world of microcontrollers and embedded control. One way

Access your microcontroller from anywhere in the world (Part 1) Microcontrollers are an amazingly cheap way to automate and control the world around you, but in a world

Access your microcontroller from anywhere in the world (Part 3) Basic server example In this example we are going to configure the module as an access point so

Access your microcontroller from anywhere in the world (Part 2) Requesting a web page over a TCP connection Now we are connected to the world, let’s try requesting

Taking temperature readings with a microcontroller may seem confusing at first sight, especially if you’re new to Arduino. In this tutorial, we simplify this as much as possible. We will

Creating a simple connection between an LED and a light sensitive resistor. In this tutorial, I’ll use two inexpensive components (a LED and a Light Resistor) and create
