This project describes an automatic light system for kitchen sink where you need sufficient light to properly clean your dishes and vegetables. It uses an ATTiny84 microcontroller with a PIR motion sensor. When motion is detected, the microcontroller turns on the light. The light source consists of 10 bright white LEDs that are driven by […]

This project describes how to measure temperature with Atmega8 and a thermistor and display it on a Nokia 3310 LCD. A thermistor is a device that changes its resistance with temperature. With a proper resistor divider network, the temperature can be measured by measuring the voltage across the thermistor. The voltage across the thermistor is […]

If you cannot afford to buy a USB programmer for AVR, don’t worry, you can make one by yourself. This programmer uses a Atmega8 microcontroller with a few external passive components. The good thing is you don’t need any USB controller because it is implemented in the firmware inside Atmega8. Yes, you are right, you […]

This project is from Extreme Electronics that describes an AVR-based (Atmega8) remotely controlled fan regulator. The control commands are received through a DVD player remote control. With three buttons on the remote control, you can turn the fan On and Off and also conotrol the speed. You can also purchase the PCB for this project […]

A wide range frequency meter is an useful tool for an electronics lab. This projects describes a frequency meter based on AT90S231 microcontroller that can measure input frequencies up to 50 MHz. The measured frequency is displayed on 6 digit multiplexed seven segment displays. It uses two external high-speed 8-bit counters (74HC590) in cascade to […]

“V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR® microcontrollers, making it possible to build USB hardware with almost any AVR® microcontroller, not requiring any additional chip.” For further details on V-USB and licensing, visit http://www.obdev.at/products/vusb/index.html This is a data logger project that reads an analog signal, converts into digital number, […]

This project describes two games – Tetris and Snake, both programmed inside an Atmega168 microcontroller. You can plug this device to a PAL TV and have fun playing the games. The circuit diagram is very simple and uses resistors to generate composite video output. For more detail: Tetris and Snake with one AVR using Atmega168 […]

JACKSONVILLE, FL (PRWEB) September 20, 2004 – – ParkerVision, Inc. (Nasdaq NMS: PRKR), announced today that ParkerVision’s SignalMAX wireless networking products have won the Best Product Award in the peripherals category at the RetailVision® Fall 2004 event, September 7-10 in San Diego. RetailVision is produced by Vision Events®, a Gartner, Inc. (NYSE: IT and ITB) […]

The AVR ATXmega chip is a newer offering in Atmel’s AVR line.  The Xmega is billed as a hybrid 8/16-bit MCU, which means you can use your normal development environment to program Xmegas (as compared to AVR32 and Atmel’s ARM line).  Because the Xmega uses a different programming interface, it does require a programmer that […]

This instructable shows, how to do your own development board for Atmega16 or Atmega32 processors.The Internet is full of home made development boards, but I think that, there is room left for another one. This board have been very useful on my projects and I actually designed and made it to serve one of my […]
