Arduino Watch Build Instructions

The Arduino Watch provides augmented sensing of temperature and range, 16-bit color drawing program, Breakout game, and also tells the time in your choice of digital, binary, or analog.  Additional sensors, devices, and programs are easy to add as any standard Arduino. The source code can be downloaded from the google code page, code.google.com/p/arduino-watch. Updates and news on the Arduino Watch can be f ...

The Word Clock – Arduino version using ATMega168 microcontroller

Major updates - A much better enclosure for this clock has been designed - check out http://www.instructables.com/id/The-Wordclock-Grew-Up/ Last month I wanted to build a special gift for my beautiful wife, Megan.  She has a teaching background in English, so what better present to make for her than a clock that uses language to tell the time for her desk at work. THE BACKGROUND The original project that I ...

The Multi-format Clock – Gift contest

I tend to have good ideas when I don't need them but when I need them I always face the black wall of no inspiration. I had to come up with an idea for a present for Jeff-O. After a long week without inspiration, I came up with this: A multiformat clock. It displays time in: Binary 3 collums Binary 6 collums Decimal Hexadecimal It can be powered by USB or wallplug and has a backlight tha slowly changes from ...

Music Playing Alarm Clock using Microcontroller AT90USB1286

This Instructable will be about designing a music player from using various building blocks. You will understand the communication between the microcontroller, memory, computer, LCD display, RTC, IR remote, and the music file decoder. I will try my best to to teach you in a way so that you can design your own projects using the skills you learn, without blindly following instructions. I know most of you wil ...

ATTiny2313 Multi-mode LED Matrix Clock

This is a mutli-mode clock project based on attiny2313. it employs a 8x8 led matrix as display. with the limited resolution, this 12 hour clock shows time in 6 different modes. The circuit employs row and column multiplexing to drive the leds, one row at a time, this gives a 12.5% duty cycle when "sets" of leds (8 of them in each of the 8 rows) are turn on briefly. Current limiting resistors are eliminated ...

Real Time Clock PCF8583 Using AVR microcontroller

Description The PCF8583 is a clock/calendar circuit based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits. Addresses and data are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 is used for programming the hardware address, allowing the connection of two devices to ...

Real Time Clock ATMega16

Description The ATMega16 chip in the M16 has a real-time counter that operates asynchronously when a 32,768hz watch crystal is connected to it, providing a real-time clock. Bascom has built-in support for the RTC, making it very easy to use time functions. The watch crystal needs to connect to pins TOSC1(pin 28) and TOSC2(pin 29). The time and date can be set via the PC serial port connection. Hardware requ ...
