![]() ![]() Not only that, actually the 2 pins of that I2C bus can still access so many other I2C devices on the exact same bus. This will reduce the GPIO pins requirement down to only 2 pins (the I2C pins SDA & SCL). The second most commonly preferred option is by using the I2C module with your LCD. ![]() However, in some projects, it can be a good option in case you don’t need the extra GPIO pins anyway. In the case of our ESP32, it can be really annoying to lose 6 GPIO pins for adding only 1 LCD module to the project. The only downside to using the bare 16×2 LCD display is that it requires 6 dedicated GPIO pins of your microcontroller. It’s a very cheap, easy to use, and reliable option to display strings of text/numbers to your system’s users. Get The ESP32 Full Course Kit (List of components)Īlphanumeric LCD 16×2 display units are the most common and easiest solutions to get some data out of your microcontroller to the world to visually see. ![]() Or just refer to the table for the exact components to be used in practical LABs for only this specific tutorial. You can either get the complete course kit for this series of tutorials using the link down below. Arduino IDE For ESP32 (Setup Guide) Hardware Components.Requirements For This Tutorial Prior Knowledge Without further ado, let’s get right into it! But it’s going to be a good starting point if you’re new to Alphanumeric LCDs in general or just want to use the generic Arduino LiquidCrystal display library. It can be useful in some projects, however, it’s not very common, due to the GPIO pins it does consume. In this tutorial, you’ll learn how to interface ESP32 with an LCD display 16×2 without I2C.
