ESP8266 Generic + ADS1115 ADC Converter

Hi blynkers,

I am trying to do really small - size iot hardware with blynk. I am using esp8266 with I2C lcd display without problems.

For analog inputs i decided to combine this board with ADS1115. But i couln’t… Here is my code, SDA connected to 0, SCL connected to 2, ADS115 address pin connected to GND. Is that possible? Sould i switch to esp32 or something else?

#include <Wire.h>
#include <Adafruit_ADS1015.h>
Adafruit_ADS1115 ads(0x48);

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = "6fb9a46b4cb84e34831d3b98b8912c78";
char ssid[] = "y-leptop";
char pass[] = "24092409";

void setup(void)
  Blynk.begin(auth, ssid, pass);


void loop(void)

  int16_t adc0;  // we read from the ADC, we have a sixteen bit integer as a result

  adc0 = ads.readADC_SingleEnded(0);

  Blynk.virtualWrite(V0, adc0);

Thank you. This will be helpful

I properly formatted your posted code…

Blynk - FTFC

A suggestion. Keep loop simple. Just and Invoke all calls using timer.
