Topic: Writing port pins as output (Read 497 times) previous topic - next topic


I've looked around but have not found if you can use this code

Code: [Select]
int powOn = 3;

void setup () {
pinMode(powOn, OUTPUT);
void loop () {
     powOn = 1  // Is this usable

// or should it just be done this way
digitalWrite(powON, HIGH);   // is this the only usable way

I guess what I'm asking is can you just set a pin high by using a 1 or do you have to use digitalWrite for


powOn = 1  // Is this usable

All that does is to set thevalue of the variable to one, not the state of the pin. You need digitalWrite or direct port manipulation to do this.


Thanks It was looking like that's the only way so Now I no thanks
