How to Build a Simple Digital Clock Using Arduino
Building a digital clock using Arduino is a fun and educational project that introduces key concepts in electronics and programming. With a few components, you can construct a fully functional digital clock that displays hours, minutes, and seconds. In this guide, we’ll go through the step-by-step process of creating a digital clock using an Arduino board, an RTC (Real-Time Clock) module, and an LCD display. Required Components: Arduino Board (e.g., Arduino Uno or Nano) : This will be the brain of your digital clock. RTC Module (DS3231 or DS1307) : A real-time clock module to maintain accurate time even when the Arduino is powered off. 16x2 LCD Display : To display the time. Potentiometer (10K) : To adjust the contrast of the LCD. Breadboard and Jumper Wires : For connecting the components. Resistors (220 ohms) : For current limiting, used in conjunction with the LCD backlight. Push buttons : Optional, for setting the time manually if desired. Power Supply (USB or External) : To power the Arduino. Circ…
