Music fortress

1. Learning objectives

In this course, we mainly learn how to use MakeCode graphical programming to make the Mobile shooter "sing" and "dance" at the same time, that is, the motor, servo, buzzer, and RGB light work at the same time.

2. Building blocks

For the building blocks steps, please refer to the installation drawings of [Assembly Course]-[Mobile shooter] in the materials or the building blocks installation album.

3. Motor wiring

The motor wiring on the left side of the car is inserted into the M1 interface of the Super:bit expansion board, and the black wire is close to the battery side;

The motor wiring on the right side of the car is inserted into the M3 interface of the Super:bit expansion board, and the black wire is close to the battery side;

The building blocks servo wiring is inserted into the S1 interface of the Super:bit expansion board, and the orange servo wiring is inserted into the yellow pin of S1.

As shown below:

! Notes:

When taking a course related to the building block servo for the first time, we need to remove the large gear installed on the servo and upload the program of this course to the micro:bit; then turn on the power switch of the Super:bit expansion board and wait for the building block servo to turn to the initial position; then, we can turn off the power, adjust the angle of the car projection rod to be parallel to the ground, and then install the servo gear. (If you have used the Mobile shooter and servo-related programs before, you can skip this step)

4. Programming

Method 1 Online programming:

First, connect micro:bit to the computer via a USB data cable. The computer will pop up a U disk. Click the URL in the U disk: https://makecode.microbit.org/ to enter the programming interface. Then, add the Yahboom smart software package https://github.com/YahboomTechnology/SuperBitLibV2 to start programming.

Method 2 Offline programming:

Open the offline programming software MakeCode and enter the programming interface. Click [New] and add the Yahboom smart software package https://github.com/YahboomTechnology/SuperBitLibV2 to start programming.

4.1 Adding extension packs

4.2 Building blocks used

The locations of the building blocks required for this programming are shown in the figure below.

4.3 Combining blocks

The summary program is shown in the figure below.

You can also directly open the microbit-Music-fortress.hex file provided in this experiment and drag it into the browser that opens the URL, and the program diagram of this project source code will be automatically opened

5. Experimental phenomenon

After the program is successfully downloaded, the micro:bit dot matrix will display a smiley face, as shown in the figure below. Turn on the power switch, the Mobile shooter will play the music "Ode", and will move forward-->backward-->left-->right-->left-->right, the RGB light will switch to different colors, and the projection rod will constantly change position.

If you need to restart, please press the reset button on the back of the micro:bit motherboard.
