const int pirPin2 = 5; // Digital pin connected to the second PIR sensor int pirState1 = digitalRead(pirPin1); // Read the state of the first sensor int pirState2 = digitalRead(pirPin2); // Read the ...

Also, a delay of 20000 milliseconds is given for the PIR sensor to warm up. This line marks the beginning of the loop() function. The loop() function is a core part of an Arduino sketch and runs ...

Dout is directly connected to pin number 14 (A0) of arduino uno. A 16x2 LCD is used ... After that, if PIR sensor senses any motion then program sends an command to open gate, stop gate, closing gate ...

in which I have shown the working of three sensors with a single Arduino. These include a PIR sensor (digital), flame-detecting sensor (digital), and flex measurement sensor (analogue). I have used ...
