Connect the kidsuno mainboard and computer via a USB cable, and connect the button module to No.2 interface and the 270° servo to the G, V and D13 interface of the mainboard. The brown wire is connected to G, the red wire is connected to V and the orange wire is connected to D13.
Please refer to Project 02: Mixer
① Drag the instruction block 
in the Events module to the script area.
② Drag the instruction block 
in the Serial module to the script area and take the baud rate 9600 as an example.
③ Drag the instruction block
in the Pins module to the script area. Since the button module is connected to D6 of No.2 interface on the mainboard, then change the number 0 to 6 .
④ Drag the instruction block 
in the Control module to the script area.
⑤ Drag the instruction block
in the Serial module to the script area.
⑥ Drag the instruction block 
in the Pins module to the script area and put it into the block , then change the number 0 to 6.
⑦ Drag the instruction block 
in the Control module to the script area and change the number 1 to 0.2.
⑧ Complete Program
Click
to upload the complete program to the kidsuno mainboard and power up, then click 
in the serial monitor area to set the baud rate to 9600. The serial monitor will print the value read by the button module, when you press the button on the module, it will output a low level (0); when you release it, it will output a high level (1).
This is the variable module. Let’s look at it!
There are commonly used declare global numeric variable type integer name assigned to 0, variable and Set variable to 0 instruction squares:
When you need to use this variable, drag the block directly into the script area to edit it!
It is a conditional statement code executing if-then function: If the logical judgment statement in 
is satisfied, the code statement below then is executed.
It is a conditional loop statement, it will loop forever if the condition in is satisfied.
Set the 270° servo to 93°. When the button on the module is pressed, the long arm of the breaker will be raised; when released, it will be lowered. (press the button and then release it will complete a beat.)
