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… ...

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… ...

Objective: The purpose of this lab is to build a standalone prototype Arduino Uno clock with the skills learned throughout the labs of this course. This clock gadget will expand and test our abilities ...

ardunio alarm clock In this project, we designed an Arduino based Real Time Clock with alarm. A Real Time Clock or RTC is a battery powered clock that measures time even when there is no external ...

Makers and Arduino enthusiasts searching for a project to keep them busy this weekend may be interested in this ... – It uses a DS3231 I2C real-time clock with battery input to set and maintain ...

This project aims to build a digital clock using a real-time clock chip (DS3231) with battery backup, a liquid crystal display (JHD 204A), and an Arduino Uno board. Let us try to design our own ...

Controlling the signals sent to the slave clocks and keeping them synchronized are the main tasks of this master clock. The National Time synchronization protocol is supported by the firmware in the ...

Our project is to make a 9V battery adaptor plug to be used at DC jack/socket on the Arduino board. Fig. 1: Arduino board. This DIY 9V battery power adaptor is built using a drinking straw, aluminium ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...
