Hi everyone. Today I will smoothly control
the speed of the EV3 motor in Scratch using arrow keys or the second
motor. And what will be driven? The motor speed can be set by the “Motor A set power block”. In this block we can enter the power in percent. In the place of the entered value we can substitute the variable. Now, by changing this value, we can change the motor power. In the first example, let’s set the power with the arrow keys. We can set the power with another motor.
