WebbArduino - Home WebbC: for analog input pins 0-5. D: for digital pins 0-7. So, all you need to do for a given digital pin, is to find which port (B, C, D) and which number is associated to that pin. Then, knowing that information, there’s a way to directly change the pin’s state in your Arduino code. Let’s see how to do that.

WebbOn Arduino, defining a pin function becomes a lot easier and more readable: int led1 = 13; // LED connected to digital pin 13, port B, pin 5 void setup() { // make the pin for led1 an output pinMode(led1, OUTPUT); // do other outputs as well... void f() { // flash led 1 digitalWrite(led1, LOW); delay(50); Webb22 okt. 2024 · The Arduino framework provides the pinMode function for this.
