SECOND VERSION
Use joystick to control computer game.
To control the speed of robot we have to transform the analog values from interval (-490,490,) to digital from interval (-250,250).
We should use proportional and the linear function y = ax + b.
S4A is a Scratch modification that allows for simple programming of the Arduino open source hardware platform. It provides new blocks for managing sensors and actuators connected to Arduino. There is also a sensors report board similar to the PicoBoard one.
