![]() ![]() ![]() The instructions and data are fed to the LCD module, though these data pins. Pin7 to Pin14 (DB0-DB7): These are data pins.A high to the low signal at this pin will permit the module. Pin-6 (E-enable): This pin is meant for permitting the LCD module.Logic HIGH at this pin actuates read mode and logic LOW at this pin actuates write mode. Pin-5 (R/W- Read/Write modes): This pin is used for choosing between Read & Write modes.If we make the RS -pin low and feed an i/p to the data lines, then this will be treated as a command. If we make the RS -pin HIGH and feed an i/p to the DB0 to DB7 (data lines), this i/p will be treated as data to show on the LCD screen. Pin-4 (RS- Register select pin): The JHD162A has 2-registers such as data register and command regisThe logic high at RS-pin chooses data register and logic low at RS-pin chooses command register.The voltage at the VEE-pin describes the difference. Pin-3 (VEE): Contrast adjustment pin, Logic this is done by connecting the terminals of a 10K potentiometer to Vcc and GND, then connecting the slider pin to the VEE-pin.Pin-2 (Vcc): Power (+5V supply) to LCD module.Pin-1 (Vss): GND pin of the LCD module. ![]() The term and the functions of every pin of the LCD module are discussed below. This specific project determines LCD interfacing with Arduino board. This module makes a system separate which can take i/p and display the equivalent output. LCD module can be formed with two or more types of driver ICs together with the LCD screen which is normally found in embedded systems. Hence special types of LCD drivers are implemented to drive the display. This display works with voltage pulses only with specific timing and also voltage levels. These displays even though look simple, but it is really hard to make it work. LCD display modules are usually found in all types of embedded devices. ![]() The advantages of the LCD display include size, low cost, power efficiency, etc. The term LCD stands for “Liquid Crystal Display” is made use of different types of devices like from small display devices to large display devices like calculator, TVs, etc. ![]()
