RTC based automatic LED lamp

Monday, December 17th, 2018

Dilshan Jayakody published a new build: This is real-time clock based automatic LED lamp which we originally designed to use as night light. This lamp can programmed to turn on and off at the specific time of the day. For example, it can program to turn on at 6 PM...

Using DS1307 and DS3231 real-time clock modules with Arduino

Friday, December 12th, 2014

John Boxall over at Tronixstuff has posted a detailed tutorial on how to on how to use DS1307 and DS3231 real-time clock modules with Arduino:  There are two main differences between the ICs on the real-time clock modules, which is the accuracy of the time-keeping. The DS1307 used in the first...

Arduino command-line tool “MiniPirate”

Thursday, May 1st, 2014

Olivier writes: This command-line enables "Quick" Arduino prototyping without compilation. Reading analog values, dis-/enabling ports and even I2C register manipulations are done in seconds instead of minutes. I will shows you how to set the time of a "DS1207" I2C realtime clock as well as executing some basic operations. The impatients...

Digital clock using 7 segment display controlled using TV remote

Thursday, January 23rd, 2014

Zxlee wrote a post on his blog detailing his digital clock on 7 segment controlled with TV remote: When the Arduino first power up, it will display time information on 7 segment displays. Besides that, the LCD will display the time, date, temperature and day of week information. Basically, this is the main part...

A DS1307 library for AVR Atmega

Wednesday, December 18th, 2013

Davide Gironi has posted a DS1307 library for AVR Atmega: The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar. This library set and get year, month, day, hour, minute and second from this RTC. Setup parameters are stored in file ds1307.h This library was developed on...

Chips: DS1307 I2C real-time clock

Friday, September 4th, 2009

This is an old version, see the latest version on the documentation wiki. The DS1307 is a simple, inexpensive I2C real-time clock, it's somewhat similar to the PCF8563 that was previously demonstrated with the Bus Pirate. This chip has some nice features. It has internal capacitors on both oscillator pins,...
