The following table gives you an overview of all components and parts that I used for this tutorial. I highly suggest the modules with I2C because the connection to the board is very easy and there are only 2 instead of 6 pins used. Most LCD displays have either 2 rows with 16 characters per row or 4 rows with 20 characters per row. If you are for example only sending data from sensors to a database on a Raspberry Pi, than you are able to view the output remote from your PC by connecting to the database.īut there are use cases like an indoor weather station, where you want to see the output like the current temperature directly and not when you are on you PC. But there is a time when your system will go live. This is great and a big time saver when you are doing prototyping. Most of the time we use the serial plotter of the Arduino IDE to visualize our solutions or output of a sketch. As bonus I show you how you can create custom characters like a heart on the screen super fast and easy. ![]() In this tutorial you learn how to connect your microcontroller with a LCD display and how to make your first sketch to display whatever you want on the LCD screen.
