#19 Push Button Counter | Interface |

Welcome Learners to Learn4U,
In this video 🎥, we'll guide you through creating a Push Button Counter using an Arduino. This project is perfect for beginners and those looking to enhance their electronics and programming skills. Let's dive in!

Project Overview:
In this tutorial, we'll build a simple counter that increments each time a push button is pressed. The count will be displayed on an LED or an LCD screen, providing a visual indication of the number of presses.

Components Needed:
- Arduino UNO
- Push Button
- LED (optional)
- 10K ohm Resistor
- Breadboard
- Jumper Wires
- LCD Display (optional)
- USB Cable
- Arduino IDE

Circuit Diagram:
1. Connect the push button to digital pin 2 on the Arduino.
2. Connect one side of the push button to the 5V pin and the other side to a 10K ohm resistor, which is then connected to the ground.
3. (Optional) Connect an LED to digital pin 9 with a 150-ohm resistor.
4. (Optional) Connect the LCD display according to the standard 16x2 LCD pin configuration.

Code Explanation:
We'll write a simple Arduino sketch to read the button state and increment the counter each time the button is pressed. The code will also handle debouncing to ensure accurate counting.

Steps:
1. Setup the Circuit: Follow the circuit diagram to connect all components.
2. Upload the Code: Open the Arduino IDE, paste the provided code, and upload it to your Arduino board.
3. Test the Counter: Press the button and observe the count increment on the Serial Monitor or the LED blink.

Troubleshooting:
- Ensure all connections are secure.
- Check the button and resistor connections.
- Verify the code for any typos or errors.

Conclusion:
Congratulations! You've successfully built a Push Button Counter using Arduino. This project can be expanded by adding more features like an LCD display or multiple buttons for different functions.
