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 ...

RTClib: for accessing the RTC module. See RTClib. Make sure these libraries are installed before opening the sketch. Note that the sketch consists of five files in the sketch folder. Copy the ...

arduino-led-matrix-clock 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.

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 ...

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino… ...

For the most part, the build is what you would expect: a 16×8 LED Matrix display driven by a TLC5920 LED driver, with an Arduino that uses a DS1307 RTC (real-time clock) with a coin cell battery ...

The outer LEDs are used to show the minutes (to the nearest 5) and a 4x4 pixel font to show the hour on the inner LEDs.The unit has no buttons. The time is ...

After I finished the morse code generator I came to the conclusion something important was missing. But what??? Looking at my desk, in our kitchen, in our livingroom it became clear: almost all ...

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 ...
