ST7565 LCD Interfacing with MSP430 microcontroller

Displaying content on a normal alphanumeric display is very limited ,we have to be limited with the font size and we can't draw any graphics also. but convention Graphics lcd are really very expensive so here is the solution, you can use ST7565 monochrome  LCD to display your large font text and graphics . the reason behind using this LCD is ,it is really very cheap and can be powered with 3 volts supply. so it is really good for battery powered application.

Project Description 

       however you can use almost any microcontroller to display content on this LCD, may be that micro controller is PIC , AVR or MSP430 , but in this demonstration we will be using Microchip MSP430G2211 Microcontroller from Texas Instrument .

Atmel AVR ATMega16 Interfacing WIth 16x2 char LCD

    An alphanumeric low cost LCD Display is very essential for may small and big projects to Display various type of information. Hitachi HD44780  Chipset based 16x2 char LCD is Really very cheap and easily available in the local market.

Project Description:-

  In this project we are going to learn various things about this chip set and displaying text on this LCD. The HD44780 16x2 char LCD screen Use 4 bit parallel interface with backlight.

This Primary Objective in this project are:-

1.  Displaying  "Hello Word!! LCD " message on the scree.
2.   Interfacing The LCD to the Microcontroller Using  4 Bit Mode.
3.  Generating and Displaying Custom Char on the LCD Screen. click here for custom char

IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller


        This little project will demonstrate how you can use your old NEC IR protocol based TV,DVD or VCR remote control to control you home appliances like fan bulb or virtually anything.

Consumer IR protocols    
    There are a number of consumer Infrared protocols out there and they have been used for every single purpose possible i guess, like PDA laptops and other consumer appliances. RC-5 & RC-6 by Phillips , RCA are few examples of consumer IR protocols.

       In this demonstration we will stick the to NEC protocol by NEC corporation,
