Step 2: Explain the code:

//Check if the magnet close to hall sensor 

 void draw() {
   statePin=arduino.digitalRead(hallPin);
   if ( statePin==Arduino.HIGH) {
     image(stoneMandrel1, 0, 0);
   } else if (statePin==Arduino.LOW) {
     image(stoneMandrel2, 0, 0);
   }
 }

Step 3: Compile the code and download it.

Step 4: After running, a target will display on screen. When the magnet close to hall sensor, then observe the result.

Result

After run the program, following picture will display:
