The project consists of controlling a servomotor using ** Only a Blynk BUTTON ** that connected to the ESP8266 NODEMCU activates the Servomotor from 0 to 180 degrees and after 5 seconds returning from 180 to 0 degrees.
It is the first time you use the ESP8266, and it cannot be used to apply automatic closing after 5 seconds of pressing the button.
What should I do so that my current programming works with a single button and the servo automatically returns after 5 seconds.
This is my current program.
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <Servo.h>
char auth[] = "qxVlIzxoGj9E7yVkfIWpQdMYuT7FX-ZS";
char ssid[] = "ARRIS-1E42";
char pass[] = "99CA7C7B3720ACAC";
Servo servo;
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
servo.attach(D4);
}
BLYNK_WRITE(V1){
servo.write(0);
}
BLYNK_WRITE(V2){
servo.write(180);
}
void loop()
{
Blynk.run();
}
