This Logic Analyzer project allow you to monitors and captures a number of digital signals. It uses PC to display the data processing. The system consists of ATmega88-20PU AVR microcontroller as main processor and some simple components used for the interfacing with the PC, the man and the probes.
The Low Cost Telemetry Device (LTD) provides a low cost, minimal parts count Telemetry keyer using an Atmel’s ATMega8 Microcontroller. The LTD sends data by measuring voltage levels of up to four analog channels via its on-chip 10-bit Analog to Digital Converter (ADC) and converting them to numbers and sending the measurements via Morse Code. [...]
The project built to track cats. It will log when they go in and out of the house. You can see what cats favorite time to go out is. The project can sent SMS messages if a cat goes missing for a certain amount of time.
This project shows you how to build thermometer with multiple sensor. The project use AVR ATMega168 as main processor and DS18×20 1-Wire® Thermometers as temperature sensor. It can monitor up to 16 DS18×20 thermometers, with a variable logging rate of 5 to 9999 seconds. The data is displayed on a multi-page LCD display and send [...]
