Microsoft MakeCode Blocks Editor Code

The program shown to the right was created using the Microsoft MakeCode

Blocks Editor for the BBC micro:bit. It demonstrates the control of stepper

motors, normal motors and servos, all of which can be connected to the

All-in-one Robotics Board.

When Button A on the BBC micro:bit is pressed, a stepper motor connected to

motor outputs 1 and 2 will turn in the forward direction 180°; ordinary motors

connected to motor outputs 3 and 4 will turn in opposite directions (Motor 3 at

10% speed, and Motor 4 at 100%); a servo connected to servo output 1 will turn

to the 180° position if it is a standard servo, or will turn full speed in one

direction if it is a continuous rotation servo; and finally, a servo connected to

servo output 8 will turn to the 0° position, or will turn full speed in the opposite

direction to Servo 1.

When Button B on the BBC micro:bit is pressed, Stepper 1 will turn 100 steps in

the opposite direction to Button A (the stepper motor block allows turning to be

set in either a certain number of degrees or steps; the default number of steps is

200, but this can be changed using the block shown in the ‘On Start’ section);

Motor 3 will be turned off; Motor 4 will turn in the opposite direction to Button

A at 50% speed; and finally, servos connected to servo outputs 3 and 6 will be

set to the 90° position.

When Buttons A and B on the BBC micro:bit are pressed together all motor and

servo outputs on the All-in-one Robotics Board will be switched off.

In the same way as the stepper motor steps value can be changed, if the

Robotics Board I2C chip address has been changed, a new address can be

selected in the package – see the ‘robotics.ts’ file in the MakeCode package for

instructions.

Note: These programs use the Kitronik Robotics Board package available on

Microsoft MakeCode (the green blocks shown here).
