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.

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 ...

Arduino Real Time Alarm Clock DS3231 with TM1638. Arduino Clock with Battery backup (real time clock), Time, Date, Alarm, Temperature, TM1638 seven segment module output and input, Display Sleep mode.

Presented here is an LED-based 2D GPS Based Dot-Matrix Display Clock. This project is for making a GPS based LED dot-matrix clock.

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 purple. Let's dive right ...

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 ...

The other is a DS3231 real time clock with built-in crystal. A CR2032 keeps it all running. The main body, the outer ring, the bottom, and the buttons are 3D printed in PLA.

Each Pixie module is designed to host two gorgeous little Lite-On LTP-305G/HR 5×7 LED dot matrix displays, which we suspect have been impulse purchases in many a shopping cart.

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

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 ...
