nd month. The system has an battery backup so that it can run over all the time even during the power failure. Totally there are 31 LED`s for indicating the date and 12 LED`s for indicating the Month and 7 LED`s to indicate the day. In our project we are using the popular 8 bit microcontroller AT89C2051. It is a 20 pin microcontroller. Here is a schematic drawing:
