 Next we need to define the `BLDCDriver3PWM` class with the PWM pin numbers and the driver enable pin.
 ```cpp
 // define BLDC driver

 Then in the `setup()` we configure first the voltage of the power supply if it is not `12` Volts and intialise the driver.

 This is hte code of the swing-up:
 ```cpp
-target_voltage = -sign(pendulum.getVelocity())*motor.voltage_power_supply*0.4;
+target_voltage = -_sign(pendulum.getVelocity())*motor.voltage_power_supply*0.4;
 ```
 What it does really is it checks which direction the pendulum is moving `sign(pendulum.getVelocity())` and sets the very high voltage value `motor.voltage_power_supply*0.4` in the opposite direction (`-`). 
 It means that the algorithm is going to try to accelerate the movement of the pendulum (because the pendulum acceleration is caused as the reaction of the motor acceleration, but inverse direction).
