button liga/desliga

Hello, I do not understand almost anything about Arduino programming, but I’m trying to do the project where I’ll use the power button to turn them on when they are connected with a continuous signal, but I need the system to see only as a pulse and not as a continuous signal. I’ll turn the key on, it’ll only give me a pulse instead of a continuous signal on the digital inputs.

I have this project and would like to modify it to work as mentioned:

#include “MegaJoy.h”

void setup(){
setupPins();
setupMegaJoy();
}

void loop(){
// Always be getting fresh data
megaJoyControllerData_t controllerData = getControllerData();
setControllerData(controllerData);
}

void setupPins(void){
// Set all the digital pins as inputs
// with the pull-up enabled, except for the
// two serial line pins
for (int i = 2; i <= 54; i++){
pinMode(i, INPUT);
digitalWrite(i, HIGH);
}
}

megaJoyControllerData_t getControllerData(void){

// Set up a place for our controller data
// Use the getBlankDataForController() function, since
// just declaring a fresh dataForController_t tends
// to get you one filled with junk from other, random
// values that were in those memory locations before
megaJoyControllerData_t controllerData = getBlankDataForMegaController();
// Since our buttons are all held high and
// pulled low when pressed, we use the “!”
// operator to invert the readings from the pins
for (int i = 2; i < 54; i++){
controllerData.buttonArray[(i - 2) / 8] |= (!digitalRead(i)) << ((i - 2) % 8);
}

// Set the analog sticks
// Since analogRead(pin) returns a 10 bit value,
// we need to perform a bit shift operation to
// lose the 2 least significant bits and get an
// 8 bit number that we can use
controllerData.analogAxisArray[0] = 0;
controllerData.analogAxisArray[1] = 0;
controllerData.analogAxisArray[2] = 0;
controllerData.analogAxisArray[3] = 0;
controllerData.analogAxisArray[4] = 0;
controllerData.analogAxisArray[5] = 0;
controllerData.analogAxisArray[6] = 0;
controllerData.analogAxisArray[7] = 0;
controllerData.analogAxisArray[8] = 0;
controllerData.analogAxisArray[9] = 0;
controllerData.analogAxisArray[10] = 0;
controllerData.analogAxisArray[11] = 0;

// And return the data!
return controllerData;
}

Have a look at IDE>file/examples/digital/state change detection

Also, using code tags eliminates things like smilies in your post.
