AVR Microcontroller Projects
This site is dedicated to AVR microcontroller projects. Here you will find schematics and board-layouts , also the program-code, part-lists and pictures of the projects.
Some projects are programmed in assembler with the AVR Studio compiler and others are programmed with the BASCOM-AVR compiler.
The temperature settings and readings are communicated to/from the device over a simple 2-wire serial interface. An ATMEL ATTiny2313 microcontroller controls the serial communication to/from the DS1621.
AVR Projects Temperature Indicator
This circuit uses a Dallas DS1621 temperature sensor which indicates the temparature of the device. The temperature sensor has an termal alarm output, which becomes high when the temperature of the device exceeds a user defined value.
