A continuous servo is a type of motor that can spin around in full circles, either clockwise or counterclockwise, without stopping.
Unlike regular servos that move to a specific angle and stop, continuous servos keep rotating as long as they receive a signal.
What is the advantage of using a continuous servo over a standard servo?
Uses for Continuous Servos
Robots
For driving wheels and moving the robot around.
Conveyor Belts
To keep the belt moving continuously.
Remote-Controlled Vehicles
To control the wheels or propellers.
Rotating Displays
For turning objects continuously in a display case.
Continuous servos are great when you need something to keep spinning instead of just moving to a set position.
Continuous servos are often used in robotics to control the speed and of a robot.
Continuous Servos can be controlled using MicroBit Make code using the 'servo' extension, except that you use the continous servo blocks instead.
One advantage of continuous servos is that they can be easily controlled with a microcontroller or board.
Connecting a Servo to the microbit
You need to make sure that you select the same pin as you plugged into the microbit. For example orange control wire of the servo below is plugged into pin 0 on the breakout board.
To control a continuous servo with a micro:bit, you need to connect it to one of the .
1. Flash the code
First plug in the USB cable to send the code to the Microbit.
2. Power the Servo
Then plug the USB into the breakout board to power the servo.
If you have 2 USB cables you can avoid swapping cables by plugging both into your computer at the same time.
To stop the servo, you need to send a signal by using the 'stop servo' block.
