为什么gpio输出没有触发继电器？

问答对人有帮助，内容完整，我也想知道答案 0 嗨 Peeps，有人可以通过这个失败的简单草图来了解一下吗，看看你是否能明白为什么我的 gpio 输出没有触发我的继电器？我想了好几天都想弄明白！干杯! 史蒂夫代码：全选/* * based on- * Rui Santos project * Complete Project Details http://randomnerdtutorials.com / #include #include #include "fauxmoESP.h" #define WIFI_SSID "wifipass" #define WIFI_PASS "password" #define REMOTE_BTN_1 4 //up (D2) #define REMOTE_BTN_2 14//down (D5) #define REMOTE_BTN_3 12 //select (D6) #define REMOTE_BTN_4 5//stop (D1) #define UP "blinds Up" #define Down "blinds Down" #define Light_Block "Blinds light Block" fauxmoESP fauxmo; void setup() { // Init serial port and clean garbage Serial.begin(115200); Serial.println(); // Wi-Fi connection wifiSetup(); // Set Buttons pinMode(REMOTE_BTN_1, OUTPUT); //up digitalWrite(REMOTE_BTN_1, HIGH); pinMode(REMOTE_BTN_2, OUTPUT); //down digitalWrite(REMOTE_BTN_2, LOW); pinMode(REMOTE_BTN_3, OUTPUT); //select digitalWrite(REMOTE_BTN_3, HIGH); pinMode(REMOTE_BTN_4, OUTPUT); //stop digitalWrite(REMOTE_BTN_4, HIGH); fauxmo.createServer(true); // not needed, this is the default value fauxmo.setPort(80); // This is required for gen3 devices fauxmo.enable(true); // You can use different ways to invoke alexa to modify the devices state: // "Alexa, turn lamp two on" fauxmo.addDevice(UP); fauxmo.addDevice(Down); fauxmo.addDevice(Light_Block); fauxmo.onSetState([](unsigned char device_id, const char device_name, bool state, unsigned char value) { //command recieved // Callback when a command from Alexa is received.
