An experiment using chained LED matrices with an ATMega328P
- ATmega328P @ 16 MHz
- 6x - MAX7219
- DS3231 RTC Module
- HC-05 BLE Module
This was connected to its UART pins. Meant to retrieve data from the buffer in the format of: HH:MM:SS:AM_or_PM, spliced, and update the display. More information is shown in main.c
I've attempted to use push buttons instead, but there was unusual issues with the buttons not registering when pressed.
Although uncompleted in a way, I felt this project needed to stop here. As there is much I needed to learn about the AVR microcontrollers.
