To compliment two of our latest product releases we have now released a brand new Arduino library for controlling WS2812 based RGB LED products. You can check out the following compatible products for this library on our website here: Digitally controlled 8x RGB LED Light Strip (HCMODU0075) Flexible Digitally Controlled RGB LED strips (HCOPTO0028) Using…
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 multiple drivers connected in series and a built-in alphanumeric font to make displaying text and numbers simple. With the new added commands it is easy to make a…
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 applications, when you interface to LEDs such as seven segment displays or LED matrix modules you’ll very quickly run out of pins. The MAX7219 can take care…
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 the Maxim MAX7219 driver IC to allow you to driver its 8 seven segment LED’s using just 3 digital pins. The display removes all the awkward things…
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 download the example blink sketch that most getting started tutorials will point you towards (http://blog.hobbycomponents.com/?p=51). This sketch is meant to be as simple a program as possible…
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 it achieves this is to try and hide away the complicated low-level parts of programming a microcontroller. When writing code for an Arduino you generally don’t need…
