Hi to all,
I've created sketch last year to monitor my aquarium.
A lot of sensors and 2 relais configured and working all fine as programmed in my sketch.
On a Arduino Yun in my sketch I use pin 22 and 23 as output for a relais. They are the A5 and A6 pin on the Analoge In header.
Where did I found this pins 22 & 23 ??? I cannot find them anymore in any pin layout schema ?
#define Rel1Pin 22
#define Rel2Pin 23
pinMode(Rel1Pin, OUTPUT);
pinMode(Rel2Pin, OUTPUT);
digitalWrite(Rel1Pin, HIGH);
digitalWrite(Rel2Pin, HIGH);
