Yet Another Arduino Timer Library? Uses hardware RTC counter as timing source Interrupt driven, accuracy not affected by blocking code "Unlimited" number of timers (limited by available RAM only) - ...

About This project implements a Digital Alarm-Clock and Timer (time counter, also with alarm).

It is based on a simple DS3231 RTC timer, an ATMEGA328 Arduino chip, a small 5-volt relay to run the 5KW contactor which will eventually control the AC. Trigger to go further ...

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 ...

The Arduino Development Platform, at the beginning in 2005, was conceived to be a simple programmable device to be used specifically for art design work. The goal was to create an interface to support ...

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

Droplet and StackAR, developed by MIT’s Media Lab, allow users to set timers or program an Arduino using light-based communication. By pressing the tool against a screen, flashes of light can ...

“Arduino Self-Timer” project presented here is a low-component count 60 seconds countdown timer. It can be powered from a 9V compact battery or suitable Arduino AC mains adaptor. Working of the ...

Arduino enthusiasts and makers looking for a project to keep them busy over the next couple of weekends might be interested in this Arduino flying start lap timer, which has been featured over on ...
