Here’s an another project, which makes an Scrolling LED display. Here 64 leds which are connected to an Matrix display. The Anodes are drived through an Driver IC UDN2981 and the cathodes are drived through ULN2803. The Atmega8515 is used in this project to control the display. The microcontroller is programmed with Bascom AVR. Circuit […]

This project gives you a simple temperature controlled fan. If the difference between real temperature and the user temperature is high then the fan will run at full speed and if the difference is low then the fan will rotate at slow speed. The speed of the fan varies with the temperature. The user can
