Youtube- Speed Variable on Scratch
Create a new variable (to represent the speed of the sprite). Initialize that speed at 0 at the beginning of the algorithm. Use the speed variable in the move statement.... Incorporating variable frequency drives into applications such as fans, pumps, and cooling towers can reduce energy use up to 50 percent at partial loads by matching motor speed to the changing load and system requirements.
Be aware of VFD running in low speed/frequency

How To Use A Speed Variable In Scratch
Variables are introduced as simple numbers which can be made available to the whole application or kept private for a particular sprite. The speed of a sprite might be a private variable whereas the score in a game might be available to all sprites.
- Many boards can also make use of the Scratch variable broadcasts, whereby a suitably named variable is created and its value is broadcast when it changes. For example, for a PiGlow board it makes sense to have variables named for each LED or ring of LEDs, and …
- How to Program Velocity in Scratch. A common method used to program velocity is by maintaining its value as a variable and using that to change the sprite's position:
- With the use of a variable speed fan, there is no need for the system to kick on in the same way, and thus, homeowners are free of the racket and noise. Humidity Control Running in longer cycles, a variable speed fan has the ability to better control humidity during the warm summer months.
