Introduction:

  • Eleventh assignment is making output device, Here i am designing Seven segment Display,In the display I am connecting seven segment as Output device.Seven segment will count the numbers from Zero to Nine. Each segment of the Seven segment is programmed accordingly. There are 8 segment i.e a,b,c,d,e,f,g and DP=Decimal point I am not using in this case.

  • First we need to design the circuit in eagle.Following schematic shows the seven segment display, we have imported the seven segment display and The Attiny44 IC

    • Figure.1

          

  • In the circuit diagram we have used 1) seven segment display 2)6 AVRISP pin connector following figure.2 shows the board file of the seven segment and i have used one jumper

    • Figure.2

          

  • then we need to hide the layers from board file so we can export the .png file in the monochrome and with resolution 500dpi.following figure shows Exported .png file for Roalnd Modela

    • Figure.3

          

  • I took outline and cut the board on modela.

    • Figure.4

          

  • Following imageshows the board from modela

    • Figure.5

          

  • following image shows the soldered board and programmed with AVR studio and also used sinaprog to uplode program on Attiny44
