Acum am luat primele 2 articole de acolo si am facut mici teste, folosind intrarea analogica A0 ca una analogica sau ca una.. digitala, adica D14... ce primeste placa Arduino fiind evidentiat de LED-ul conectat la pinul D13 si/sau pe ecranul de monitorizare seriala...
Primul sketch folosit de mine este:
// http://blog.roman-mueller.ch/index.php/2013/01/26/hc-sr501-passive-infrared-sensor-with-arduino/
#define pir A0
#define led 13
void setup() {
pinMode(pir, INPUT);
pinMode(led, OUTPUT);
}
void loop() {
digitalWrite(led, digitalRead(pir));
delay(100);
}
// http://robotic-controls.com/learn/sensors/pir-sensor-hc-sr501
int pirPin = 14; //is A0 :P
int val;
void setup() {
Serial.begin(9600);
}
void loop() {
val = digitalRead(pirPin); //read state of the PIR
if (val == LOW) {
Serial.println("No motion"); //if the value read is low, there was no motion
}
else {
Serial.println("Motion!"); //if the value read was high, there was motion
}
delay(1000);
}

int pirPin = 14; //is A0
int val;
#define led 13
void setup() {
Serial.begin(9600);
pinMode(led, OUTPUT);
}
void loop() {
val = digitalRead(pirPin); //read state of the PIR
if (val == LOW) {
Serial.println("No motion"); //if the value read is low, there was no motion
digitalWrite(led, digitalRead(pirPin));
}
else {
Serial.println("Motion!"); //if the value read was high, there was motion
digitalWrite(led, digitalRead(pirPin));
}
delay(1000);
}
