Change the speed of the motor using the up and down arrow keys.
You can select a LEGO-WeDo-compatible device from the dropdown menu:
- If you have only one motor, use the "motor" option, which will set the motor's power regardless of where it is connected on the WeDo hub.
- If you have two motors which you want to control separately, you can use "motor A" with one and "motor B" with the other.
- "lights" sets the lights' power regardless of where they are connected on the WeDo hub.
- "everything" sets the power for all the connected motors and lights.
To use set power, you need WeDo motor(s) or lights connected to your computer via a LEGO WeDo hub.
