ArduBlock code using an analog input and three digital outputs :

This ArduBlock code

Digital outputs are connected to P2 :

void setup(){
  pinMode( 11 , OUTPUT);
  pinMode( 8 , OUTPUT);
  pinMode( 10 , OUTPUT);
  pinMode( 12 , OUTPUT);
  pinMode( 13 , OUTPUT);
  pinMode( 9 , OUTPUT);
  pinMode( 19 , OUTPUT);
  pinMode( 18 , OUTPUT);
}

void loop(){
  if (( ( analogRead(A0) ) > ( 128 ) )) {
    digitalWrite( 19 , HIGH );
    if (( ( analogRead(A0) ) > ( 256 ) )) {
      digitalWrite( 18 , HIGH );
      if (( ( analogRead(A0) ) > ( 384 ) )) {
        digitalWrite( 8 , HIGH );
        if (( ( analogRead(A0) ) > ( 512 ) )) {
          digitalWrite( 9 , HIGH );
          if (( ( analogRead(A0) ) > ( 640 ) )) {
