Description Of Pin
Register Select : RS pin is used to select the register.
RW selects either read or write mode.
Enable: E enables the LCD module.
Data Pins: Pin7 to Pin14 are data Pins.
Logic High (1) – Activates Data register.
Logic Low (0) – Activates Instruction register.
Logic High (1) – Activates Read mode.
Logic Low (0) – Activates Write mode.
Vss: It is the Ground Pin of the module.
Vdd : It is the supply pin of the module.
VEE : Pin3 is used for controlling the brightness of the LCD. Normal setting of this pin is between 0.4V to 0.9V.A 10 k pot is connected to adjust the brightness of the screen.
