hi there after connecting all my alarm zones, led and buzzer, phone etc ... i have only one digital pin left.... Question can i use the analog pins to connect the leds ? instead of digitalwrite(ledpin1,high ) something like analogwrite(a1, high) ?
can this be done ? regards.
Hi I already read that page, i can only see this
Note The analog input pins can be used as digital pins, referred to as A0, A1, etc.
Note
The analog input pins can be used as digital pins, referred to as A0, A1, etc.
so if i do a pinMode(la0, OUTPUT); digitalWrite(a0, HIGH);
the a0 pin will have the behavior of a digital pin ?
thanks
You can call 'em 14/15/16/17/18/19 as well, A0 is digitalWrite(14, HIGH), A1 is 15, etc.
