    hi ..I think your system needs only keypad and lcd.

    you can use 4×4 matrix keypad. and i think 16×2 LCD is enough for mentioned operations.

     

    You can get ckt for interfacing of 89c51  with lcd and keypad here itself in EG in LABS  tab.

    Coding of interfacing is also available here itself. Follow the link below

    Your main aim should be your logic for your application and that will be very interesting.

    arithmatic operations will be purly algorithum part… first i think you should start interfacing LCD and keypad as you don’t know that part…

    here i am sending you the LCD and keypad interfaicng tutorial links….

     

    LCD

    http://www.engineersgarage.com/microcontroller/8051projects/interface-lcd-at89c51-circuit

     

    Keypad

    http://www.engineersgarage.com/microcontroller/8051projects/interface-keypad-AT89C51-circuit

     

    as soon you cover these let know your algo we try to create a good algo first then we will go for the code…

     

    and Kaubstubh has post that link since it is a combination of LCD and keypad interfaicng with 8051…..

    hi all.

     

    i am also interested in this project.

    whaty i am trying is i save two variable and multi ply them, save the value in third variable.

    but the problem is controller multiply them in Binary and thats y i am getting wrong values.

     

    before sending the result to LCD , i must convet it to ASCII.

    bt i dnt have any idea abt that.

     

    can anyone help me in this.
