PIR controlled LED matrix display

Posted on Saturday, May 28th, 2011 in AVR, LEDs, sensors by the machinegeek

Sometimes it’s handy to have a message display when persons enter a specific area. Having the message appear only when someone approaches brings more attention it, and can be useful for holiday displays, directions or warnings. In this project by Jer from Volts and Bytes, an Atmega8 is used to activate a Sure Electronics 0832 LED matrix display when motion is detected by the attached PIR sensor.

The C source and supporting files are available in this zip file.
