Question

一般用什么APP来通过WiFi控制arduino

Answer 1

项目需要的硬件如下： Arduino Uno Ethernet Shield LED灯 2个. 电阻 2个. 面包板（可选） 连接导线 路由器一个 项目要的连接管脚如下： LED 1 --> pin 6 to ground LED 2 --> pin 7 to ground 项目需要的软件如下： Eclipse IDE Arduino IDE 1.x.x LED 1 --> pin 6 to ground LED 2 --> pin 7 to ground 项目需要的软件如下： Eclipse IDE Arduino IDE 1.x.x Step 1: 在 Arduino上编程如下：#include "etherShield.h" #include "ETHER_28J60.h" int led2 = 7; int led1 = 6; static uint8_t mac[6] = {0xAA, 0xBB, 0xCC, 0xDD, 0xBB, 0xAA}; // this just needs to be unique for your network, // so unless you have more than one of these boards // connected, you should be fine with this value. static uint8_t ip[4] = {192, 168, 0, 15}; // the IP address for your board. Check your home hub // to find an IP address not in use and pick that // this or 10.0.0.15 are likely formats for an address // that will work. static uint16_t port = 80; // Use port 80 - the standard for HTTP ETHER_28J60 e; void setup() { e.setup(mac, ip, port); pinMode(led1, OUTPUT); pinMode(led2, OUTPUT); digitalWrite(led1, LOW); digitalWrite(led2, LOW); } void loop() { char* params; if (params = e.serviceRequest()) { if (strcmp(params, "?cmd=1") == 0) { digitalWrite(led1, HIGH); } if (strcmp(params, "?cmd=2") == 0) { digitalWrite(led1, LOW); } if (strcmp(params, "?cmd=3") == 0) { digitalWrite(led2, HIGH); } if (strcmp(params, "?cmd=4") == 0) { digitalWrite(led2, LOW); } e.respond(); } } Step 2: 制作安卓APP package com.androidarduino; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.DefaultHttpClient; import android.app.Activity; import android.os.Bundle; import android.os.StrictMode; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.Toast; public class MainActivity extends Activity implements OnClickListener{ @Override protected void onCreate(Bundle savedInstanceState) { StrictMode.ThreadPolicy policy = new StrictMode. ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); super.onCreate(savedInstanceState); setContentView(R.layout.main); View led1on = findViewById(R.id.led_1on); View led1off = findViewById(R.id.led_1off); View led2on = findViewById(R.id.led_2on); View led2off = findViewById(R.id.led_2off); led1on.setOnClickListener(this); led1off.setOnClickListener(this); led2on.setOnClickListener(this); led2off.setOnClickListener(this); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } public void commandArduino(String url){ try { HttpClient httpclient = new DefaultHttpClient(); httpclient.execute(new HttpGet(url)); } catch (Exception e) { } } public void onClick(View thisView) { switch(thisView.getId()){ case R.id.led_1on: commandArduino("192.168.0.15/?cmd=1"); Toast.makeText(getApplicationContext(), "led_1on",Toast.LENGTH_LONG).show(); break; case R.id.led_1off: commandArduino("192.168.0.15/?cmd=2"); Toast.makeText(getApplicationContext(), "led_1off",Toast.LENGTH_LONG).show(); break; case R.id.led_2on: commandArduino("192.168.0.15/?cmd=3"); Toast.makeText(getApplicationContext(), "led_2on",Toast.LENGTH_LONG).show(); break; case R.id.led_2off: commandArduino("192.168.0.15/?cmd=4"); Toast.makeText(getApplicationContext(), "led_2off",Toast.LENGTH_LONG).show(); break; } } }

Answer 2

可以自己设计一个app，用app inventor，然后加入arduino的组件就可以了
