An Arduino Alarm Clock is cool and popular project and most of the Electronic Hobbyists at least builds it once. You can find lots of Alarm Clock Projects with simple LCD and few settings, but here we ...

Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.

You’ve doubtless seen those ubiquitous clock modules, especially when setting clocks for daylight savings time. You know the ones: a single AA battery, a wheel to set the time, and two or thr… ...

Note: This project requires 5v 2A minimum to work and failure on giving this current rating will result in non-function of the circuit. Functions of Switches as follows. S1: Menu (Time Date Edit ...

Circuit Diagram and Explanation: This is very simple, cheap and interesting project for the learner. In this LED Binary Clock Circuit, we have used Arduino Nano to control the whole project like ...

It is a LED clock built using the Arduino including controls for setting the time and the LEDs off. Each hour and minute digit is represented in binary form. It is a 6 by 4 display of neon tubes that ...

In this project, a digital alarm clock with alarm and temperature abilities built using an Arduino Uno R3 microcontroller for the Spring 2021 term of the Embedded Systems Programming course. This ...

When I thought of doing a Chess Clock with Arduino, the goal was to build using simple programming without use class and work with the AVR register. The base used was Arduino Reference The most ...

Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino. The alarm clock is ...

If not needed A0 and A1 must be tied to ground. The analog inputs will not work if both are at 0V during startup of the Arduino. To activate the clock the second jumper of JP2 must be connected (D4 to ...
