In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and ...

Although ready-made real-time clock (RTC) modules for microcontroller projects are available in every online shop, an inspired electronics hobbyist would rather put together something from a few ...

Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and GND to the ground rail. For the data connections, wire SDA to Pin 10, SCK ...

[Daniel]’s word clock only uses eight discrete components: an ATMega328p, a DS1307 real time clock ... with links to the Arduino code, the EAGLE board files, and link to buy the board on ...

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 ...
