Arduino 32x8 LED Dot Matrix Clock

A simple LED dot matrix clock project based on Arduino Nano (ATmega328 chip).

Schematics:

Arduino Nano 3.0:

Parts:

• Arduino Nano 3.0 (ATmega328).
• Real Time Clock DS3231RTC.
• 32x8 LED Dot Matrix Display Module (with MAX7219 chip).
• LDR sensor.

Instructions:

To set the clock, use the Arduino IDE Serial Monitor and follow on screen instructions.

Serial Monitor output:

>> Arduino 32x8 LED Dot Matrix Clock!
>> Use <dd/mm/yyyy hh:mm:ss> format to set clock's date and hour!

arduino-led-dot-matrix-clock's Issues

static clock

how to make the clock static on the display?

error code

Compilation error: no matching function for call to 'DS3231::DS3231(const uint8_t&, const uint8_t&)'

what is wrong?
