There are some parts you need to 3D print yourself, 5 of them totally. You can find them in 3D-File/Stl folder. You can also modify these parts in 3D-File/Parts folder if you konw how to use solidworks.
In this project, I use Arduino Uno as my controller, and you also need some other parts as BOM table showing below. Feel free to replace some of them if you are familiar with arduino projects.
| Electronics | quantity | Image |
|---|---|---|
| Arduino Uno | 1 |  |
| Toggle Swtich | 1 |  |
| DC-005 Power Socket | 1 |  |
| HD-1160A Servo Motor | 2 |  |
First you need to wire your electronics referring to below diagram.
Note that you must apply 5V power to the circuit if you are wiring like me.
Then assemble 3D printing parts and wired electronics together.
You can use a longer servo stick instead of using 3D printing stick part like I did.
Finally, upload arduino code to your board and have fun!
