Story

Introduction:

In this tutorial, we will guide you through the process of creating a simple logic gate tester using an Arduino. We will set up an LCD display to show the results of the AND and NOT logic gates based on the input from two buttons. This project is a great way to learn about basic electronics, programming, and the workings of logic gates.

Components Needed

Arduino board (e.g., Arduino Uno)
16x2 LCD display
2 Push buttons
Breadboard and jumper wires
220-ohm resistors (for pull-down configuration)

Conclusion

This tutorial detailed the setup and coding of a basic logic gate tester using an Arduino and an LCD display. You can extend this project by adding more logic gates, such as OR, NAND, or NOR, and displaying their results on the same LCD. Experimenting further with this project will deepen your understanding of logic operations and Arduino programming. Happy coding!
