Вот моя конфигурация выводов для моего ультразвукового c датчика с Arduino
1. VCC pin to +5v on the Arduino board.
2. Trigger to digital pin 7 on your Arduino board.
3. Echo to digital pin 6 on your Arduino board.
4. GND with GND on Arduino.
Вот мой код, который я выполняю
#include <ESP8266WiFi.h>
#include <FirebaseArduino.h>
// Set these to run example.
#define FIREBASE_HOST "......" //cannot share for privacy purpose
#define FIREBASE_AUTH "......" //cannot share for privacy purpose
#define WIFI_SSID "SSID"
#define WIFI_PASSWORD "PASSWORD"
const int pingPin = 7;
const int echoPin = 6;
String myString;
void setup() {
Serial.begin(9600);
// connect to wifi.
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("connecting");
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(500);
}
Serial.println();
Serial.print("connected: ");
Serial.println(WiFi.localIP());

Код предназначен для получения информации от моего датчика расстояния * ультразвука c и последующего ее отображения в базе данных Firebase в реальном времени с помощью модуля WiFi esp8266. Пожалуйста, укажи мне, что я делаю неправильно, и мне нужна дополнительная информация, дай мне знать
