Propeller LED Display (AT89S52)

Posted February 4, 2014 by Chris

"People often use ARDUINO platforms and other microcontrollers (pic, avr) for making a propeller LED display and it is a bit costly to have them. I am trying to make one using AT89S52 microcontroller. I’m using a 11.0592MHz crystal and a 7805 for power supply. LEDs are connected to the PORT0 of the MCU, 8 leds are used for displaying letters….the wheel is attached to 6mm shaft and 1000RPM metal gare motor."
