AVR displays body temperature on a Nokia 3310 LCD using Atmega8 microcontroller

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 […]

Open Source USB AVR Programmer for Students and Hobbyists using Atmega8 microcontroller

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

AVR based remote controlled fan regulator

Leave a Comment / AVR ATmega Projects, Video - Camera - Imaging Projects / Ibrar Ayyub

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

50 MHz range frequency counter using ATtiny45 microcontroller

Leave a Comment / AVR ATmega Projects / Ibrar Ayyub

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

Tetris and Snake with one AVR using Atmega168 microcontroller

Leave a Comment / AVR ATmega Projects, Game - Entertainment Projects / Ibrar Ayyub

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

Build an AVR Xmega Prototyping Board using AVR microcontrollers

Leave a Comment / AVR ATmega Projects, How To - DIY - Projects / Ibrar Ayyub

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

Reading Switches with using Attiny microcontrollers

Leave a Comment / AVR ATmega Projects, Other Projects / Ibrar Ayyub

There have been several Instructables dealing with outputs from the ATtiny2313 and similar AVR devices. For example, http://www.instructables.com/id/Ghetto-Programming%3a-Getting-started-with-AVR-micro/, http://www.instructables.com/id/Drive-a-Stepper-Motor-with-an-AVR-Microprocessor/. Working on the latest one from The Real Elliot, which showed how to control stepper motors, I found that it would be really helpful to be able to run alternate sections of code in the same
