I am new to aurdino.in arduino uno I want to interface lcd as well as keypad .thus all my digital pins including those for PWM are used up.on the other hand i need one PWM signal for another part of my project.kindly guide me.
Did you also used the analog pins? Just like PWM, analog in is just an extra functions besides digital I/O.
Hi, THESE LCD Displays use only 2 pins: Analog 4 and 5
