I would like to control a 360-degree continuous rotation servo using Blockly in Synthiam ARC, specifying the duration of movement instead of a specific angle. Which blocks should I use to achieve this? I assume I need to use the "Move Servo" block to identify the servo number. What other blocks should I use to set the duration and speed for the servo's movement? Should I also consider using the "Move Forward" block, which allows setting left speed, right speed, and duration in milliseconds?
