The Battery sAVR is an intelligent battery capacity meter that will log the discharge of a single primary or secondary cell over a period of time. But it’s more than a dummy load and data logger, with Atmel ATtiny26 AVR microcontroller, the Battery sAVR can emulate 3 different types of loads in real-time – [...]
The is a simple and less expensive amateur long-period seismometers by using PIC microcontroller and other new chips, such as switched capacitor filters. Long-period seismometers are useful for detecting and analyzing distant teleseismic activity (worldwide). Main part of the project is PIC 14000, MAX7401, and AD8628. The PIC controls A to D, time integration, etc. [...]
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 [...]
The aim of this project is to help blind people, or people with Color blindness problem, who has difficulty to differ colors. The system will analyzes the color of a surface and then pronounces its result through speaker.
The project uses TRS17xx as color sensors. The voltage at sensor output will be varies depend on rays [...]
The temperature recorder project uses a microcontroller PIC12F683 as main processor, a 32kBytes Serial EEPROM which can store up to 32,000 measurements and a thermistor as temperature sensor. The temperature is measured and stored at user programmable intervals with range from 1 second to 256 seconds. The time interval is set by programming it and [...]
