Button

ไลบารีใช้ในการจัดการขา IO ของ Arduino ให้เป็น Switch Input

This library allows you to use GPIO pins of Arduino, ESP32, 
and ESP8266 (including touch pins for ESP32) as buttons or switches. It is easy to use.



Support the following Event-Driven
 -Press
 -Release
 -Click
 -DoubleClick
 -Hold (long press)
 -LongHold (more than LongPress)

//  Change Arduino editor font to "Courier New" for specify correct ESP32 image below.
//  1.Click the link at the line following File > Preferences > More preferences can be edited directly in the file.
//    This will open the .Arduino15 (or something like that) folder.
//  2.Exit the Arduino IDE
//  3.Open the file preferences.txt in a text editor.
//  4.Search for the line that starts with "editor.font".
//  5.Change the first word following the equals sign on that line to the "Courier New".
//    like this "editor.font=Courier New,plain,11"
//  6.Save the file.
//  7.Start the Arduino IDE. The editor should now be using the font you chose.
