If statement and Rc button/Receiver

I'm having trouble making the if statement (first line of the void loop) to work. When I upload the program it renders it as true constantly. I am using a button and receiver to send an input to digital pin 3 but it seems it doesn't matter if I hook up the receiver or not. Any help would be greatly appreciated.

#include <MeccaBrain.h>
#include <Wire.h>
#include <Adafruit_MotorShield.h>


Adafruit_MotorShield AFMS = Adafruit_MotorShield();
Adafruit_DCMotor *leftLeg = AFMS.getMotor(2 );
Adafruit_DCMotor *rightLeg = AFMS.getMotor(1);

void setup() {

  pinMode(3, INPUT);

  AFMS.begin();
  leftLeg->setSpeed(150);
  leftLeg->run(RELEASE);
  rightLeg->setSpeed(150);
  rightLeg->run(RELEASE);
  
  pinMode(chainPin1, OUTPUT);
  pinMode(chainPin2, OUTPUT);
  pinMode(chainPin3, OUTPUT);
 
  Serial.begin(9600);

  
  
  

  //"Discover" all the modules (make them blue-colored instead of green-colored)
  //for some unknown reason, I have to repeat it from time to time
  for (int i = 0; i < 50; i++)
  {
    chain1.communicate();
    chain2.communicate();
    chain3.communicate();
  }
  //delay to be sure that all modules are ready
  //if some module is "not discovered" than it will remain green and later this module will behave strangely
  delay(2000);
}

void loop() {
  if (digitalRead(3) == HIGH)
  {
    leftLeg->run(BACKWARD);
    rightLeg->run(BACKWARD);
    delay(5000);
    leftLeg->run(RELEASE);
    rightLeg->run(RELEASE);
    delay(1000);
    setJoint(RIGHT_ARM_PITCH, 150);
    delay(500);
    setJoint(RIGHT_ARM_ROLL, 220);
    delay(500);
    setJoint(RIGHT_ARM_ELBOW, 190);
    delay(4000);
    setJoint(RIGHT_ARM_PITCH, 0);
    delay(500);
    setJoint(RIGHT_ARM_ROLL, 160);
    delay(500);
    setJoint(RIGHT_ARM_ELBOW, 130);
    delay(2000);
    leftLeg->run(FORWARD);
    rightLeg->run(BACKWARD);
    delay(2500);
    leftLeg->run(RELEASE);
    rightLeg->run(RELEASE); 
    delay(1000);
    leftLeg->run(FORWARD);
    rightLeg->run(FORWARD);
    delay(5000);
    leftLeg->run(RELEASE);
    rightLeg->run(RELEASE);
    delay(1000);
    delay(10000); 
  }
  else
  {
    
  }
}
