我正在尝试打开和关闭连接到 Tinterkit 继电器的 LED 灯泡。
借助官方的 Arduino Wifi shield,我正在使用连接到互联网的 Arduino UNO r3。
我已经做了一个简单的网站,有两个按钮可以向我的 Xively 帐户发送 1(开)或 0(关)。
我编写了一个代码来检测最后发布的频道值。该代码工作正常,我能够大约每 3 秒检测一次 1 或 0。问题是继电器不通勤。
拜托,我会很感激你的帮助来解决这个问题。
这是代码:
#include <SPI.h>
#include <WiFi.h>
#include <HttpClient.h>
#include <Xively.h>
#include <TinkerKit.h>
char ssid[] = "XXXXXX";
char pass[] = "XXXXXX";
int state;
int status = WL_IDLE_STATUS;
char myIntStream[]="LED";
char xivelyKey[] = "XXXXXX";
#define FEED_ID XXXXXX
TKMosFet relay(O0);
XivelyDatastream datastreams[] = {
XivelyDatastream(myIntStream, strlen(myIntStream), DATASTREAM_INT),
};
XivelyFeed feed(FEED_ID,datastreams,1);
WiFiClient client;
XivelyClient xivelyclient(client);
void printWifiStatus() {
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
}
void setup() {
Serial.begin(9600);
Serial.println("LED light bulb");
Serial.println();
while ( status != WL_CONNECTED) {
Serial.println("Connecting to internet ...");
status = WiFi.begin(ssid, pass);
Serial.println("");
delay(5000);
}
Serial.println("Connected to wifi");
printWifiStatus();
}
void loop() {
Serial.println();
Serial.print("Datastream is:");
Serial.println(datastreams[0]);
Serial.print("LED value = ");
state = datastreams[0].getInt();
Serial.print(state);
if(state == 0){
relay.off();
Serial.println(" => Light is on.");
}
else if(state == 1){
relay.on();
Serial.println(" => Light is off.");
}
xivelyclient.get(feed, xivelyKey);
}
