AVR GPS Locator

In this project i have interfaced an GPS with AVR microcontroller, the ATtiny2313 gets the location from the GPS and display it over the LCD display. This project also have the feature of marking a place with its name. For entering the Name of the place i have used the PC-AT Keyboard. At starting the microcontroller will display the latitude and longitude on the LCD display and if you need to mark the place, then press the Button SW1. Now the microcontroller will ask you to enter the name through the PC keyboard. Type the Name of the place of maximum 16 characters and press Enter key to store it. The ATtiny2313 will store the name and the...

Stepper motor Control with Atmega16

With this project you can control a unipolar stepper motor. You can control both the speed and the direction of the motor. The speed and direction and can changed with help of the keypad. The data's are displayed over the LCD display. A 4x4 keypad is used for entering the speed and selecting the direction. Load the hex file into the chip, dont forget to select the internal oscillator at 10Mhz. Then switch on the circuit and select the direction by pressing the corresponding key (Left or Right). Then enter the speed through the numeric keys and press the Enter key to start the operation. To switch off the motor press the separate switch which...
