CH27-D - 360 Servo Function

The 360 Degree Servo Motor has a 3-wire connector on the end that can plug directly into the pins on the back of the Bit Board.

Make sure the Orange Wire is closest to the number 13 for the Pin 13 column.

Then the Brown Wire should be closest to the micro:bit (in the - row) and the Red Wire will be in the middle (the +5v row).

A 360 Degree Servo is also called a "Continuous Rotation Servo" because it can spin around continuously without the hard stops that a 270 Degree Servo has.

We're going to load the following code for our 360 Servo Function program: https://makecode.microbit.org/_9icMywi2F...

We've created three functions, goForward, goBackward, and stopMoving.

We're passing a parameter (theDelay) when we call the function which tells the function to run for a specified amount of time.

The result of using the functions is a simple and clearly labeled set of instructions in our main forever loop.

If this code looks familiar, it's basically what we use for our Bit Board Rover, which features two 360˚ servos used to move the Rover around.

Once the code is loaded it should start running immediately.

You can power the micro:bit via the USB cable you used to load the code, but now that we are using servos we recommend using a battery pack plugged into the Bit Board.

The Blue Pins on the Bit Board provide extra power (5 volts instead of 3 volts) by boosting the voltage coming from the battery pack. This helps improve servo performance, especially with multiple servos.

The servo will spin one direction for two seconds, then stop for one second, then spin the opposite direction for two seconds, and stop again for one second.
