4 inch 4 digit LED display

This microcontroller based counter can be used in industrial unit as a manual (button) based or automatic sensor based counting application. The displays are four inches high standard industrial user size.

At the hearth of this circuit is ATmega8 28 PIN microcontroller IC that can be programmed in C language for various types of application. The MCU is clocked from its internal 8MHz RC oscillator, thus does NOT require any external crystal. The microcontroller is connected to ULN2003 IC and few transistors that helps in driving large size 12 volt LED digit displays. The control board has a 10 PIN FRC cable that is used to download programs using a AVR programmer.

Few i/o ports of the microcontroller are available on the male headers. They are listed below.

  • PC0 (Increment Signal)
  • PC1 (Decrement Signal)
  • PC2 (Reset Signal)
  • PC3
  • SDA
  • SDL

 

Main board is powered by a 12V transformer and the board has onboard rectifier diodes and filter capacitor to convert this to DC current required for the display. Additionally the board also has 7805 voltage regulator to generate stable 5v supply required for the microcontroller.
