Changing mode using switch button

Projects Programming

hi I'm making a combination of useless box and shy box, so there's two modes and to change between the two modes, I want to use a switch button. How to write the code?

In setup, declare a pin as pinMode(x, INPUT_PULLUP);
In loop, check the pin and respond accordingly
if(digitalRead(x)
mode(1);
else
mode2();

where can I put the code?

Hello
You can use the Arduino IDE for example.

Preferably, inside the Arduino :stuck_out_tongue:

If there are only going to be two modes, and the code is fairly basic then this kind of setup could work well:

(Note - as in the Wokwi, only two of the switch poles are used, an outer pole to ground and the middle pole to a digital pin).

#define SWITCH_PIN 13

void setup() {
  pinMode(SWITCH_PIN, INPUT_PULLUP);
  Serial.begin(115200);
}

void loop() {
  digitalRead(SWITCH_PIN) ? doModeOneStuff() : doModeTwoStuff();
}

void doModeOneStuff() {
  Serial.println("Doing Mode One Stuff");
}
void doModeTwoStuff() {
  Serial.println("Doing Mode Two Stuff");
}

Of course you might need to swap the order around inside the digitalRead(SWITCH_PIN) ? doModeOneStuff() : doModeTwoStuff(); line. And all of the Serial lines can be removed when you are finished debugging with them.
