A small and simple Arduino library to handle physical buttons using internal pull-up resistors, making wiring and reading easier.

• Easy-to-use, minimal interface.
• Automatically uses INPUT_PULLUP (no need for external resistors).
• isPressed() method to check button state.
• Great for projects with multiple buttons.

1. Download the repository as a ZIP file or clone it to your Arduino libraries folder

git clone https://github.com/hanzeelvilla/MyButtonIO.git

2. Place the MyButtonIO folder into your Arduino libraries directory (typically Documents/Arduino/libraries on most systems).
3. Restart the Arduino IDE if it was open during installation.

To use the library in your Arduino sketch, include the MyButtonIO.h header file.

#include "MyButtonIO.h"

Create a MyButtonIO object by passing the GPIO pin number where your button is connected

MyButtonIO myBtn(12); // Button connected to pin 12

Before checking the button state, initialize it in the setup() function. This sets the pin mode to INPUT_PULLUP automatically

void setup() {
  myBtn.init();
}

Use the isPressed() method inside the loop() to check if the button is being pressed. It returns true when the button is pressed (LOW)

void loop() {
  if (myBtn.isPressed()) {
    Serial.println("Button Pressed!");
  }
}
