FIRST VERSION
Me Joystick Module is used to control the moving direction of cart and the interactive video game. It has an analog port and should be connected to the port with black ID on mBot.
In neutral position X-Axis and Y-Axis give number 0, but it oscilate between -2 and 2. When you moves stick to other position number is changing. The minimum is -490, the maximum is 490.
Be careful about the value 490. When you push joystick to maximum position the value is 486-490, because it is analog value.
