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 […]

Easy Serial on the ATtiny

Easy Serial on the ATtiny

Introduction The Atmel tinyAVR MCU’s are great little chips for projects but can prove difficult to debug. Some ATtiny chips do not have direct support for hardware based serial and therefore the Serial object is unavailable in your code, however, it is easy to add a Software Serial object and view output in the Arduino […]
