LRemote Control Classes

These control classes are provided to create UI controls to the canvas created by LRemote:

LRemoteLabel: a static text label
LRemoteButton: a rectangular button with a text label
LRemoteCircleButton: a round, circular button with a text label
LRemoteSlider: a slider with adjustable range and initial value
LRemoteSwitch: a on/off switch
LRemoteJoystick: an analog joystick control

To use these classes, declare them in the global context:

#include <LRemote.h>

LRemoteLabel label;
LRemoteButton button;
LRemoteSlider slider;
LRemoteSwitch switchButton;
LRemoteCircleButton bigButton;

void setup() {
}

And adjust the text label, position and size in setup() function, and then call LRemote.addControl() to add the control to the remote UI canvas.

void setup() {
  LRemote.setGrid(3, 5);
  
  // Add a push button
  button.setText("Press Me");
  button.setPos(1, 1);
  button.setSize(2, 1);
  button.setColor(RC_PINK);
  LRemote.addControl(button);
  
  LRemote.begin();
}
