Santosh, Due to 8x8 Keyboard to be not an usual configuration, I can sugest you take some example code project with 4x4 + lcd and extend it. +++
For driving motor you can build discrete H-bridge (which is general way to control DC motor rotation direction) or use some integrated bridge like L298, LMD18201 or similar. For buttons see any microcontroller related tutorial, this is the most basic thing ever. As for lcd, if is has HD44780 compatible controller (which i'm almost sure it has) you

Hi All! I am trying to make a 0-15 volt regulated power supply with lcd display. I am using AT89S52, ADC0804 and JHD162A lcd Display. I am using Assemby code to program the microcontroller. Every thing is working fine. The ADC is sending the digital data output in binary value which I am converting to Decimal and then to ASCII digits to (...)
A text editor Project: I want it to read ASCII text (7 bit)from an general EEPROM of I?C bus. I'll be plugging a 24C08 with preloaded text, and it will read/write the text there. Then the MCU will simply transfer the text to a 2x16 (serial) lcd (that one we use mostly). I have a 8051 MCU P80C31 and also a 8052 MCU SM8952A. Which one can (...)
Dear All, If we want copy the data from CD to memory chip we need a PC and memory Card Reader , Is it possible without the computer and card reader?. My idea of this project is to read the information(audio or video or data) from the CD or DVD using DVD ROM and send the data to memory chip.( SD, Micro SD). also want to display information on to
plz help me out and tell me how this can be done..........
What information you need exactly? I can see that, you just checked IO status to display a character on lcd. But you may see lot many characters on display for a single key press.

Hi, I am using a 8051 based controller,and i would like to know about Humidity sensor and i want to interface with lcd and display the Humidity value, so can anyone give me idea or suggestions how to interface with this, awaiting ur kind reply. Thanks & Regards dayal
Not sure how the 8051 fits into this. Or did you mean that you have an lcd connected to the chip, and that you are communicating serially from the PC. If this is the case, it is a matter of modifying the driver you are using in the 8051, and monitoring the serial port. I assume you are trying to make a simple moving message display?. A (...)
