Hi Guys,
I’m new to Arduino and require some advise on my project.
I’m currently working on a project which require me to control varies type of motor etc(Servo, Stepper & DC motor) via web browser. But currently i had an issue that i’m only able to control 1 type a motor at a time. Once i input all 3 types of codes together, it seem not working. Im using Arduino UNO, Arduino Ethernet shield & Adafruit motor shieldV2.3 on this project. I need some advise. my source code are attached below.
#include <SPI.h>
#include <Ethernet.h>
#include <Servo.h> //Servo Motor Library
//Include Adafruit DCmotor lib
#include <Wire.h>
#include <Adafruit_MotorShield.h>
#include "utility/Adafruit_PWMServoDriver.h"
//Assign Motor types variable
// Create the motor shield object with the default I2C address
Adafruit_MotorShield AFMS = Adafruit_MotorShield();
// Or, create it with a different I2C address (say for stacking)
// Adafruit_MotorShield AFMS = Adafruit_MotorShield(0x61);
// Select which 'port' M1, M2, M3 or M4. In this case, M3
Adafruit_DCMotor *myMotor = AFMS.getMotor(1); //DC motor on M3 port
// You can also make another motor on port M2
//Adafruit_DCMotor *myOtherMotor = AFMS.getMotor(2);
// Connect a stepper motor with 200 steps per revolution (1.8 degree)
// to motor port #2 (M3 and M4)
Adafruit_StepperMotor *myMotorStepper = AFMS.getStepper(200, 2);//Stepper use M3 & M4
//Servo motor
Servo myservo; // create servo object to control a servo
// twelve servo objects can be created on most boards
int pos = 0; // variable to store the servo position
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0x05 }; //physical mac address
byte ip[] = {
192, 168, 1, 178 }; // ip in lan (that's what you need to use in your browser. ("192.168.1.178")
byte gateway[] = {
192, 168, 1, 1 }; // internet access via router
byte subnet[] = {
255, 255, 255, 0 }; //subnet mask
EthernetServer server(80); //server port
String readString="";
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip, gateway, subnet);
server.begin();
Serial.print("server is at ");
Serial.println(Ethernet.localIP());
//Include DCmotor setup
AFMS.begin(); // create with the default frequency 1.6KHz
//AFMS.begin(1000); // OR with a different frequency, say 1KHz
// Set the speed to start, from 0 (off) to 255 (max speed)
myMotor->setSpeed(40);
//myMotor->run(FORWARD);
//turn on motor
myMotor->run(RELEASE);
myMotorStepper->setSpeed(30);//Stepper Speed
myservo.attach(9); // attaches the servo on pin 9 to the servo object, Adafruit on Servo 2
}
//Main loop
void loop() {
// Create a client connection
EthernetClient client = server.available();
