Tutorial: How to use Mini ADC Converter ADS1115

The Mini ADC Converter ADS1115 is an ideal device for makers who want to acquire precise analog data. With 4 channels, it can measure up to four sensors simultaneously, making this module perfect for both environmental monitoring projects and industrial applications.

What you need

• Arduino Uno or compatible
• USB cable
• Analog sensors (e.g., LM35)
• AAA batteries

Steps

1. Connect the ADC converter ADS1115 to the Arduino I2C interface using the cables.
2. Check that the module’s power supply voltage is adequate (check the datasheet).
3. Install the Adafruit_ADS1015 library for Arduino from the library manager.
4. Configure the channel and sensitivity of the ADC in the code.
5. Read data from the ADC converter ADS1115 using the readADCSingleEnded() method.
6. Display the read values in serial or on an LCD display.
7. Test the accuracy of the data with connected analog sensors.
8. Modify the code to adapt it to your project requirements.

Example code

I2Cdevlib.h
Adafruit_ADS1015 ads;
void setup() {
  Serial.begin(9600);
  if (!ads.begin()) {
    while (1); // blocco il programma se non riesce a connettersi.
  }
}
void loop() {
  int value = ads.readADCSingleEnded(0, ADS1015_REG_CONFIG_CQUE_NONE); // leggi canale 0
  Serial.println(value);
}

Mini project

Create a weather monitoring system that records temperature and humidity in real-time. Use the ADC converter to acquire data from the LM35 (temperature) and DHT11 (humidity) sensors.

Common mistakes

• Fail to install the necessary library correctly.
