How to use the TFT display 2.2″ QVGA with Arduino

Story The main purpose of this project is to build a system based on chip ATMEGA328P, Arduino compatible, and interface it with a 2.2" QVGA TFT display using the library ILI9341. As an alternative to the self-build system you can use an Arduino Pro 3.3 V/ 8 MHz board or similar. This system works well and can be very useful for many applications, as data-loggers, graphic terminal, etc. A great advantage of ...

Building the Colossus LED Display

The 2014 NC Maker Faire was a huge turning point for Maniacal Labs. It was there that the idea for the AllPixel and what is now BiblioPixel got their start. It’s also where we showed off our first custom-built LED display, the 24×24 LPD8806 matrix. At nearly 24 inches square, and 1 pixel per inch, it was certainly impressive. But we left the Maker Faire with a desire to go bigger. Not just more pixels… but ...
