Arduino code from video:
void setup() {
// put your setup code here, to run once:
pinMode(3,INPUT);
pinMode(6,INPUT_PULLUP);
pinMode(5,INPUT);
pinMode(4,INPUT);
pinMode(2,INPUT);
Serial.begin(57600);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.print("This is the pull-up input D6 ");
Serial.println(digitalRead(6));
Serial.print("D5 input has no pull-up ");
Serial.println(digitalRead(5));
Serial.print("D4 input has no pull-up ");
Serial.println(digitalRead(4));
Serial.print("D3 input has no pull-up ");
Serial.println(digitalRead(3));
Serial.print("D2 input has no pull-up ");
Serial.println(digitalRead(2));
Serial.println();
delay(1500);
}
