13.5. Hardware Connection#


Connect the motor to M1 and the two buttons to J1 port on Nezha-A master box. ../../_images/neza-a-case-10-03.png

13.6. Programming#


13.6.1. Prepare the programming#

Steps for preparation please refer to: Arduino 3 in 1 Breakout Board

Import the libraries and the subsidiary libraries of Nezha-A master box and then import the libraries of the two buttons:PlanetXButton-main.zip Download and import the self-defined library connections for Nezha-A master box: RJPins-main.zip

13.6.2. Sample Code:#

// 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, 100);   //Set the speed of the motor connecting to M1 at 50%
  }
  if (buttonJ1.isPressed(D)) {    //While button D is pressed
    nezhaA.brakeMotor(M1);
  }
}

13.6.3. Result#

After powering on, press button C to drive the motor and press button D to stop driving.
