Arduino Uno R3 Displaying RC Receiver PWM Signal Output

Connecting RC Receiver channel signal output to Arduino Uno R3 D3, compiling, uploading the sketch and displaying the pwm value in Serial Monitor.

Sketch

#define pwmIn 3 // connect RC receiver signal output to Arduino Uno D3

int signal;

void setup() {
   pinMode(pwmIn,INPUT);
   Serial.begin(115200);
}

void loop() {
   signal = pulseIn(pwmIn,HIGH);
   Serial.println(signal);
   delay(10);
}
