Multi mode LED Matrix Clock (1)

ATTiny2313 Multi-mode LED Matrix Clock Using Atmega

This is a mutli-mode clock project based on attiny2313. it employs a 8×8 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 …

Wire Digital Temperature Sensor DS18B20

Arduino – One Wire Digital Temperature Sensor – DS18B20

The one wire Digital Temperature Sensor – DS18B20 from Maxim (formerly Dallas) is a great chip for measuring temperature in your projects. Luckily, there is a Dallas Temperature library for the arduino which makes using this sensor very easy. The most recent version of this library can be found at http://www.milesburton.com/?title=Dallas_Temperature_Control_Library We used version 3.6.0 …
