text ( "--", 370, 150);
text ( "0-", 370, 200);
//show current num
text ( resistance+unit, 0, 10);

Step 3：Uploading the code and compiling it successfully.

Step 4： Putting the resistor ready to measure between the yellow and the black lines on the graph, watching resistance on Processing.

==Result==

The graph will display the current resistance.
