4 channel relay and google assistant with D1 mini

I need help with programming.

Blynk program:
#define BLYNK_PRINT Serial

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth = “GMUVXXUvUR98mdd3K0YPozbkrr5lMb58”;

// Your WiFi credentials.
// Set password to “” for open networks.
char ssid = “ASUS”;
char pass = “97983740”;

void setup()
{
// Debug console
Serial.begin(9600);

Blynk.begin(auth, ssid, pass);
// You can also specify server:
//Blynk.begin(auth, ssid, pass, “blynk-cloud.com”, 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
}

void loop()
{
Blynk.run();
}

RGB Program:
// Load Wi-Fi library
#include <ESP8266WiFi.h>

// Replace with your network credentials
const char* ssid = “pcnet-386”; // Input your wifi network name
const char* password = “3rdbencher3c”; // Input your wifi password

// Set web server port number to 80
WiFiServer server(80);

// Variable to store the HTTP request
String header;

// Auxiliar variables to store the current output state
String relay1State = “off”;
String relay2State = “off”;
String relay3State = “off”;

// Assign output variables to GPIO pins
const int relay1 = 14; // GPIO14 D5
const int relay2 = 12; // GPIO12 D6
const int relay3 = 13; // GPIO13 D7
void setup() {
Serial.begin(115200);
// Initialize the output variables as outputs
pinMode(relay1, OUTPUT);
pinMode(relay2, OUTPUT);
pinMode(relay3, OUTPUT);
// Set outputs to HIGH. relay active LOW
digitalWrite(relay1, HIGH);
digitalWrite(relay2, HIGH);
digitalWrite(relay3, HIGH);

// Connect to Wi-Fi network with SSID and password
Serial.print(“Connecting to “);
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(”.”);
}
// Print local IP address and start web server
Serial.println("");
Serial.println(“WiFi connected.”);
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
server.begin();
}

void loop() {
WiFiClient client = server.available(); // Listen for incoming clients

if (client) { // If a new client connects,
Serial.println(“New Client.”); // print a message out in the serial port
String currentLine = “”; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client’s connected
if (client.available()) { // if there’s bytes to read from the client,
char c = client.read(); // read a byte, then
Serial.write(c); // print it out the serial monitor
header += c;
if (c == ‘\n’) { // if the byte is a newline character
// if the current line is blank, you got two newline characters in a row.
// that’s the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what’s coming, then a blank line:
client.println(“HTTP/1.1 200 OK”);
client.println(“Content-type:text/html”);
client.println(“Connection: close”);
client.println();

// turns the GPIOs on and off
if (header.indexOf(“PUT /14/on”) >= 0)
{

This project aims to use google assistant to control RGB LED strips. Is the black wire supposed to be connected to V+ ?
I uploaded the above 2 codes to the D1 mini, but when testing, the 3 relays didn’t activate, send help thanks a lot.

Pleas first of all format the code as code see How to use this forum

than it becomes more readable and I might actually look at it when I'm not busy...

secondly: did you do any debugging besides of "relays don't activate"?
Do you know if it's a hardware or software error (e.g. have you checked wether or not the output pins get the correct reading)? Without having read the code in detail, you do some wifi shenanigans, have you checked if the device correctly connects to the wifi etc.?
