### Prepare the programming

Steps for preparation please refer to: [Arduino 3 in 1 Breakout Board](https://www.elecfreaks.com/learn-en/Arduino-3-in-1-box/Arduino-3-in-1-box.html)

Import the libraries and the subsidiary libraries of [Nezha-A master box](https://www.elecfreaks.com/arduino-3-in-1-master-control-box.html) and then import the libraries of the [two buttons](https://www.elecfreaks.com/planetx-button.html):  [PlanetXButton-main.zip](https://github.com/elecfreaks/PlanetXButton/archive/refs/heads/main.zip)
Download and import the self-defined library connections for [Nezha-A master box](https://www.elecfreaks.com/arduino-3-in-1-master-control-box.html): [RJPins-main.zip](https://github.com/elecfreaks/RJPins/archive/refs/heads/main.zip)

### Sample Projects:

```
// Language ArduinoC
#include <RJPins.h>
#include <NezhaA.h>
#include <PlanetXButton.h>

PlanetXButton buttonJ1(J1);    //Create an instance of PlanetXButton category
NezhaA nezhaA;    //Create an instance of NezhaA category

void setup() {
  nezhaA.begin();    //Initiliaze the buzzer, motor, servo and light
}

void loop() {
  if (buttonJ1.isPressed(C)) {    //While button C is pressed
    nezhaA.setMotorSpeed(M1, 50);   // Set the speed of the motor connecting to M1 at 50%
    delay((2) * 1000);    //Pause 2000ms
    nezhaA.brakeMotor(M1);    //Stop the motor connecting to M1
    nezhaA.setMotorSpeed(M2, 100);   //Set the speed of the motor connecting to M2 at 100%
    delay((1) * 1000);
    nezhaA.brakeMotor(M2);    //设Stop the motor connecting to M2
  }
  if (buttonJ1.isPressed(D)) {    //While button D is pressed
    nezhaA.setMotorSpeed(M1, -50);
    delay((2) * 1000);
    nezhaA.brakeMotor(M1);
    nezhaA.setMotorSpeed(M2, -100);
    delay((1) * 1000);
    nezhaA.brakeMotor(M2);
  }
}
```
### Result
After powering on, press button C and the car drives forward for 2 seconds and the raise its folklift; press button D and the car reverses for 2 seconds, then it puts the folklift down.
