(sorry for my english, I use a translator)
Hello everyone. I have a question about the code because I have the web server code shown below and I don't know how to change the code to control 2 or 3 pins with one button?
Previously I used BLYNK and I changed the code so that I could turn on 3 pins with one button:
BLYNK_WRITE(V0){
int value = param.asInt();
value ? digitalWrite(D1, HIGH) : digitalWrite(D1, LOW);
value ? digitalWrite(D0, HIGH) : digitalWrite(D0, LOW); //zwykla
value ? digitalWrite(D5, HIGH) : digitalWrite(D5, LOW); //zwykla
}
However, in this case I don't know how to do it because honestly I have no idea about it.
I tried copying and pasting some lines after the comma, but it ended with an error in the code. Maybe you write such codes with your eyes closed, but unfortunately I can't...
with control via several pins, I need LEDs because I can't connect e.g. 5-7 LEDs because they don't have that much power. so I have to split it into several pins. Therefore, I need to change the code so that when the button is turned on, it will turn on 2 or 3 (or maybe more) pins:
and this is the code we wanted to modify:
//192.168.4.1
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <EEPROM.h>
/* Put your SSID & Password */
const char* ssid = "Name"; // Enter SSID here
const char* password = "Password"; //Enter Password here

load1 = EEPROM.read(1);

Serial.print(load2); Serial.print(" ");
Serial.print(load3); Serial.print(" ");
Serial.println(load4);
digitalWrite(Relay1, load1);
digitalWrite(Relay2, load2);
digitalWrite(Relay3, load3);
digitalWrite(Relay4, load4);
WiFi.softAP(ssid, password);
IPAddress apip = WiFi.softAPIP();
Serial.print("visit: \n");
Serial.println(apip);

I don't know whether to risk it.
