Arduino LCD with keys simulation in proteus

Arduino LCD with keys simulation circuit diagram

In this article we will learn how to Interface Arduino with LCD and Keys simulation in proteus.
In the last post we will learn how to Interface Arduino with K-type Thermocouple Amplifier breakout circuit in proteus. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

Working…

An Arduino LCD with keys is a combination of an Arduino board, a Liquid Crystal Display (LCD), and a set of keypad buttons. This setup allows you to display information on the LCD screen and interact with it using the keypad buttons.
