PIR sensor with and without arduino
Hello guys here you can see how interface PIR sensor with and without arduino board. use of this sensor is very easy , by connecting some wires as shown in diagram you can use this sensor. here is circuit diagram :- After connection as per diagram you need to upload this simple code :- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- #define pir 10 #define op 13 int val; void setup() { pinMode(pir, INPUT); pinMode(op, OUTPUT); } void loop() { val = digitalRead(pir); if(val == HIGH) { digitalWrite(op, HIGH); } else { digitalWrite(op, LOW); } } -----------------------------------------------------------------------------------------------------------------------...
