With the Me 4 Button module produced by Makeblock, it is an easy-to-use button module that you can assign tasks to your projects or control your robots.
Me 4 Button module is an analog working module. When each button is pressed, you will get different values between 0-1023 from the OUT pin.
With its 6P6C RJ25 connector, it is fully compatible with Me BaseBoard, Me BaseShield and MakeBlock Orion.
With 3 pins (VCC-GND-OUT) on the right of the RJ25 connector, you can easily use it on Arduino and other software development platforms.
It must be connected to the PORT-6, PORT-7 or PORT-8 connectors of the MakeBlock Orion board.

Features:

• Fully compatible with Me BaseBoard, Me BaseSield, MakeBlock Orion cards with RJ25 connector
• Power and status indicator with LED
• Compatible with Arduino and other software development platforms
• 4 Buttons status control with one Analog output
• Easy wiring with RJ25 connector
• Operating voltage : 5VDC
• Size : 24 x 48 x 16 mm

Package Included:

• 1 x Makeblock Me 4 Button

Arduino Sample Code:

 # include
Me4Button btn(PORT_6);
uint8_t keyPressed = KEY_NULL;
uint8_t keyPressedPrevious = KEY_NULL;
void setup ()
{
serial . begin ( 9600 );
}
void loop ()
{
keyPressedPrevious = keyPressed ;
keyPressed = btn.pressed();
if (keyPressedPrevious != keyPressed )
{
if ( keyPressed == KEY_1)
{
serial . println ( "Button1 Pressed" );
}
if ( keyPressed == KEY_2)
{
serial . println ( "Button1 Pressed" );
}
if ( keyPressed == KEY_3)
{
serial . println ( "Button1 Pressed" );
}
if ( keyPressed == KEY_4)
{
serial . println ( "Button1 Pressed" );
}
if ( keyPressed == KEY_NULL)
{
serial . println ( "Buttons Not Pressed" );
}
}
}
