Basic Character LCD Hookup Guide
Printing data to a serial terminal is a great way to see data from a microcontroller. But, what if you want to make your project mobile and see sensor values away from your computer? Liquid crystal displays (LCDs) are a great way to output a string of words or sensor data to a display for visual feedback. In this tutorial, we'll learn about LCDs and how to print a strings of words to a basic character LCD.
To follow along with this tutorial, you will need the following materials. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
While not necessary, we'll be using a breadboard holder to hold the circuit together.
Depending on your LCD's specifications, the input voltage may be 3.3V or 5V. For the LCDs listed below, the input voltage for the LCD must be 3.3V. The logic levels will be the same as the input voltage.
You will need a soldering iron, solder, and general soldering accessories.
If you aren’t familiar with the following concepts, we recommend checking out these tutorials before continuing.
