Some readers wrote me asking more “real” examples using this display… in this post I’ll write a sketch to use it as a thermometer.
This is the last post in this tutorial and it’s about an Arduino sketch that receives a text string from the serial port and displays it on your display with a scrolling effect.
In my previous tutorial, you learned how to display a fixed text, coded and saved in Arduino’s program memory, on your display. Now you’re going to learn how to display dynamic text…
In this post, I’m going to show how to display some characters on your display…
A new blog post about my led matrix display with a first example about interfacing it with Arduino…
Few weeks ago I brought from SureElectronics a led matrix display. The product is made by 4 8×8 led matrices and an Holtek HT1632C controller: In this first tutorial, I’m going to show how to communicate with control chip… COMMUNICATION PROTOCOL HT1632C chip implements a protocol similar to SPI; you can control the chip through 3 pins: CS (chip select)…
