Rewrite the code above so that the variable is substituted for the value 150 and the motors are spinning in the opposite directions. b) Create a second variable motorSpeed2. Using motorSpeed and motorSpeed2, modify the code so that the motor B spinning at twice the speed of motor A in the same direction.

Transcribed Image Text:8. Answer the following the questions based on the code snippet below:
void loop () {
// Set motor A speed and direction
analogWrite (enA, 150); // Speed control (0-255)
digitalWrite (inl, HIGH);
digitalWrite (in2, LOW);
// Set motor B speed and direction
analogWrite (enB, 150); // Speed control (0-255)
digitalWrite (in3, HIGH);
digitalWrite (in4, LOW);
}
a) Create a variable called motorSpeed that will store the speed of the dc motors. Rewrite the code
above so that the variable is substituted for the value 150 and the motors are spinning in the
opposite directions.
b) Create a second variable motorSpeed 2. Using motorSpeed and motorSpeed2, modify the code so
that the motor B spinning at twice the speed of motor A in the same direction.
