Welcome to Mini Microbit Handle repository

Handle Control Tinybit car
1.Preparation

1-1.Learn how to use  micro:bit handle

1-2.Learn how to communicate between the Tiny-bit robot car and the micro:bit handle

The handle is shown below. The communication between the Tiny-bit robot car and the micro:bit handle is the communication between two micro:bit boards. They use the wireless networking communication method.

Programming method:

Mode 1 online programming: First, we need to connect the micro:bit to the computer by USB cable. The computer will pop up a USB flash drive and click on the URL in the USB flash drive: http://microbit.org/ to enter the programming interface. Add the Yahboom package: https://github.com/lzty634158/Tiny-bit and https://github.com/lzty634158/GHBit to program.

Mode 2 offline programming: We need to open the offline programming software. After the installation is complete, enter the programming interface, click【New Project】, add Yahboom package: https://github.com/lzty634158/Tiny-bit and https://github.com/lzty634158/GHBit, you can program.

2.Learning goal

2-1. Learn about using Radio graphically programming blocks

2-2. Learn about using GHBit graphically programming blocks

2-3.Learn how to use micro:bit handle control Tiny bit robot car

3.Tiny bit code

The following is the location of the building blocks required for this programming.

The summary program is shown below:

5.Handle code：rocker control

The following is the location of the building blocks required for this handle code programming.

The summary program of handle rocker control is shown below:

The summary program of handle gravity control is shown below:

5.Download code

First, we need to download the microbit-Tiny-bit-code.hex to the micro:bit board on the Tiny-bit robot car.

Then, we need to download the handle control program (microbit-Handle_rocker_control.hex/microbit-Handle-gravity-control.hex) to the micro:bit board on the handle.

6.Experimental phenomena

After the download is complete, open the power  of the car. We can see that the microbit dot matix display a “T” pattern. Open the power of the handle. We can see a heart pattern on the handle and then display an “X”, as shown below. 

Next, we can control robot car by handle.

The corresponding function of the rocker control is as shown below:

The corresponding function of the gravity control is as shown below:
