“Most of our Arduino projects require a way to present us with information about their state, and very often an LED can be enough to indicate if a condition is true or false.
But, it is not uncommon that we need to display a lot more than just a Boolean state so we opt-in for using a more advanced solution in the form of a display.
In this Instructable, we will look into the Liquid Crystal Displays (or LCDs for short) and how we can connect them in our projects to display the information that we need.
