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.

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.
