First, we need to calibrate your foil sensors.
The Terminal will display values from the RC time block based on which square of foil your hand is hovering above.
These values may have an extremely large range at first. In the game, you will use the map block, which will do the math and automatically scale and translate these values for you.
Let's try it out and see what happens!
The example shows values of -260 on the far right and 610 on the far left (yours will probably be different - everything from the size and thickness of the foil squares to the size of your hands, to the humidity in the air, will have an effect). You may need to experiment with these values to finetune the game's performance.

Record the most extreme values for either side. Now that you have these values, you are ready for the next step.
Give the game a try and see how it works. If it doesn't work quite right, recheck the circuit diagrams and schematics on the first page of this project to be sure your connections are correct.
