Description
With bass wood as its structural material, we specially design an excavator learning kit.
This kit integrates three servos, two touch sensors and a joystick, which are compatible with micro:bit boards and ESP32 Easy Coding Boards. We write codes via Makecode and KidsBlock to achieve multiple creative and interesting functions.
With this kit, you can master basic sensor knowledge and have an excellent opportunity to learn programming. It is also a perfect combination of learning and entertainment which stimulates your creativity and talent.
Features
Simple assembly: For convenience, the assembly is easy and simple so that you may complete installations quickly.
Experience of excavator: You work with the machine and learn related knowledge during the experience.
Combined with programming: It integrates excavator with programming, providing you with a novel and creative programming experience.
Multiple programming: Makecode and KidsBlock programming are available, which meet the diversified programming needs and expand the range of learning.
Assembly
ATTENTION: If you are a beginner, please learn the Micro bit Basic Projects first. The angle of the servo need to be set before assembling. You may not know how to do it without the basic projects.
1. Mount battery holder and the expansion board
2. Assemble excavator side
3. Assemble excavator wheel and front baffle
4. Mount joystick and touch sensors
5. Assemble top board, base servo and base board
Set the servo angle to 90°
The angle must be set before mounting following parts. Or else the servo may be damaged.
Connect the servo to the expansion board.

ESP32 development board code file:
If you do not know how to upload code to the board, click to learn the basic projects.
After uploading the code, the servo rotates from 0 degree to 180 degree and to 90 degree. You can press the service button on the development board to have a clear look. If your servo gets no response, please check whether the wiring is correct or whether the expansion board is powered by the batteries.
6. Assemble arm and arm servo
Set the servo angle to 180°
The angle must be set before mounting following parts. Or else the servo may be damaged.
Connect the servo to the expansion board.
Download the code folder of the relevant development board.

Tutorials
1. Basic Projects
Basic projects include development board introduction, programming methods, the ways of burning codes and the usage of sensors and modules. You will have a clear understanding on the board functions.
If you are a beginner, please firstly read the introduction and using methods of development board (Micro:bit /ESP32Easy Coding Board) to learn how to program on software and how to upload code.
2. Excavator Projects
Do operations according to the tutorials of the two development boards.
