One of the basic interfacing requirements for the hobbyists or electronics enthusiasts is I/P (keypad) and O/P (LCD display)  for proyotype applications. This shield uses minimum number I/O’s that is 4 bits for LCD data and 2 control signal lines for the same. A single analog pin (Pin A0) is multiplexed to read 5 input key switches (Navigation keys). Each key has been pulled up to a different voltage level, so a different voltage will be generated every time a user selects a key. This voltage could be read by the analog pin A0 on the board. Hence saves the no of I/O pins.  The backlight of the LCD could be controlled by setting PWM (Pin D10) by adding a few lines of code.

One of the basic interfacing requirements for the hobbyists or electronics enthusiasts is I/P (keypad) and O/P (LCD display)  for proyotype applications. This shield uses minimum number I/O’s that is 2 bits(D0 and D1) for LCD data . 5 input key switches (Navigation keys), when it's activated serial data will be sent to pin  D0 by internal 2 line LCD controller. Each key has been pulled up to a different voltage level, so a different voltage will be generated every time a user selects a key. This voltage could be read by the analog pin of internal 2 line LCD controller on the board. Hence saves the no of I/O pins.  The backlight of the LCD could be controlled by setting PWM (Pin D10) by adding a few lines of code.

LCD stands for Liquid Crystal Dispaly. It can be used to display anything. They are of many types. The ones we commonly use for embedded systems, robotics, etc are of two types – character LCD and graphical LCD. The 16x2 LCD Characters have their own limitations; they can only display characters of certain dimensions. The Graphical LCDs are thus used to display customized characters and images. The Graphical LCDs find use in many applications; they are used in video games, mobile phones, lifts etc. as display units.

PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously.
