How can I move 4 servos with the gamepad?

Alright, that is easy:

If you are using jut the tokymaker, the code would be like this:

If you are using the motor shield, then the code is slightly different:

Then you have to connect the tokymaker with the Bluetooth icon (check the first steps tutorial in tokylabs.com/learn18) and click play button.

Finally, click on the gamepad icon at the top-right corner.

Hope this is clear enough!
