You could start with 40 pins 8-bit microcontroller such as Microchip PIC16F887 or Atmel AVR ATmega8515 as you will need plenty of I/O ports for the calculator project

Thanks, and But can you please tell about which Microcontroller (some number or name of it), That would be more helpful to me.
Thanks for your reply once again.

Hey thanks rwb, it helped me a lot.
And can u help me in digital electronics ideas like Making a simple calculator using some ICs which just performs the basic operations? plz reply to me.
And one more time thanks for your two transistor line follower robot.

You have to use the geared DC motor for the LFR, since this circuit is designed to be as simple as possible therefore you need to follow the requirement especially for the geared DC motor. You could use any 5-6 volt DC geared motor available on the market such as shown on this following video http://www.youtube.com/watch?v=naYwCsMtHVU

Hey rwb Iam a new user for this site, I just viewed your video on Youtube and read your blog, I constructed a two transistor Line follower just like you have written on this page, but the problem is I didn’t get a Micro-motor, so I just fixed the High RPM Toy motor . Its not working, even if I increase the voltage from 4.5V to 9.0V. I need your help solving my problem with this, plz help me , plz tell me if there are any alternatives like Amplifying the current or the voltage ( with the circuit diagrams ) plz. Plz e-mail me with your solution to my e-mail id i.e; mikelmack.mack3@gmail.com
I am waiting for your reply. Bye , n thanks for the line follower, its awesome.

It should compile with no error and warning, make sure you select the correct Device (atmega168) and Frequency in the AVR Studio Configuration Options (Project -> Configuration Options). The following is the compile result using AVR Studio version 4.17 and WinAVR 20100110:

AVR Memory Usage ---------------- Device: atmega168


Program:    4338 bytes (26.5% Full)

(.text + .data + .bootloader)
Data:        288 bytes (28.1% Full)

(.data + .bss + .noinit)

Build succeeded with 0 Warnings...

If you used the New Haven LCD, then both 2×8 and 2×24 LCD use similar controller (SPLC780D) with the 2×16 LCD. Therefore the command for both 8/4-bit data mode will be the same as the 2×16 LCD. Make sure you re-examine the LCD pins, because these LCD (2×8,2×24) use different pins compared to the 2×16 LCD.
