Manual switch with arduino

is it possible to use this kind of switch's in arduino for toggle on and off some functions?/
if soo how does the schematic and coding work for this.

Yes

how does the schematic and coding works for this?

How did you manage to sneak such a brief reply past the forum software?

5

because he can do it :grinning:

Yes, however you should use pull-up or pull-down resistors aswell.
Also keep in mind, if necessary, to implement some debouncing.

Presumably, it is a switch; it is either open or closed.

8

Assuming that the switch has 2 contacts that open and close then just connect one to Arduino GND and the other to an Arduino pin with a pinMode() of INPUT_PULLUP just like any other switch and use digitalRead() to determine whether the switch is open or closed

I could tell you but you know what the consequences for you would be..

Actually I have no idea. It just worked

somthing like this?

#define button 2
int buttonpress = OPEN;
void setup() {
  
Serial.begin(9600);
pinMode(button,INPUT_PULLUP);
}

void loop() {
  buttonpoll = digitalRead(button);
  if ( buttonpress == OPEN ){
    Serial.print("off");
   if( buttonpoll == CLOSED ){
    Serial.print("on");
     
     }
  }
}
12

What did the compiler say?

13

i was expecting this..lol...instead of open or close i tried 0 and 1
but it just power off the arduino if i close the switch on once i open the switch its powers on back

14

Yes, but that could get confusing if "closed" means digitalRead returns 0.

15

with use of 1 and 0 as int values... its just power off the arduino board..

It sounds like you have wired the switch wrongly. Post a diagram of your circuit

That looks OK if you are using pin 4 in the code (unlike the code in post #11). For now, remove the switch from the circuit and use a patch wire to connect/disconnect pin 4 from GND which is, after all, what the switch is doing

Please post the full sketch that you are using

Would this work?

#define button 4
int buttonpress = 0;
void setup() {
  
Serial.begin(9600);
pinMode(button,INPUT_PULLUP);
}

void loop() {
  buttonpoll = digitalRead(button);
  if ( buttonpress == 0 ){
    Serial.print("off");
   if( buttonpoll == 1 ){
    Serial.print("on");
     
     }
  }
}

A simple "else" is all that's required
