The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...

An LED-matrix clock made with Arduino, using a DS3231 RTC module and four MAX7219 LED-matrix controllers. It also has an ambient light sensor for controlling the brightness.

Hardware -------- Because this is an extension of the original generator the basis will be the same Arduino Uno I was allready using. A prototype shield carries the real-time clock based on a DS3231 ...

This project demonstrates how you can build a real-time clock (RTC) with a temperature display using Arduino, DS3231 RTC and SSD1306 display.

Fig. 2: Circuit diagram of GPS based dot-matrix display clock Note that the system works with two different Arduino boards, one of which (Board2) controls the dot-matrix display and the other (Board1) ...

Referring back to the circuit schematic, I designated digital pins on the Arduino for Clock, Data, and Chip Select. The host board's connections and common pins ensured proper communication between ...

Arduino Display Matrix (32 X 8 DOTS) Today, I'm thrilled to guide you through the steps to create your very own 32x8 compact LED matrix, driven by an Arduino Nano. For a double fun, the used LEDs are ...
