Display ADC Value on I2C LCD using ESP8266 NodeMCU.
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#define analogPin A0 /* ESP8266 Analog Pin ADC0 = A0 */
int adcValue = 0; /* Variable to store Output of ADC */
LiquidCrystal_I2C lcd(0x3F, 16, 2);
void setup()
{
lcd.init();
lcd.backlight();
lcd.setCursor(0,0);
lcd.print("ADC Value = ");
}
void loop()
{
adcValue = analogRead(analogPin); /* Read the Analog Input value */
lcd.setCursor(0,0);
lcd.print("ADC Value = ");
lcd.setCursor(12, 0);
lcd.print(adcValue);
delay(1000);
