Simple Push Button for MakerBit/MakeCode

Push_Button_MB

// ******************************************************
// Push button with pull-up resistor | MakerBit example
// 
// To demonstrate using a micro:bit with the push-button
// module in the 37-Sensors kit by Elegoo.
// The module has a built-in pull-up resistor, so
// the signal pin is HIGH when the button is NOT pressed.
// Pressing the button grounds the signal pin to LOW.
