I'll be using my favorite module, the ESP8266, as a controller and a KY-038 microphone sound sensor as the sensor. Wiring The KY-038 provides two outputs: one analog A0 to wire up to the ADC pin and measure through voltage changes, and one digital to wire up to a free GPIO pin to have a simple binary output. ADS1115 ADC Module Interfacing In this project we have two analog sensors (Light Dependent Resistor and Soil Moisture) to be interfaced with the ESP8266. But ESP8266 has only one 10-bit ADC which can read maximum voltage of 1V. So we are going to use an external ADC like ADS1115 for reading those sensors. The electrical scheme is very simple: using the ESP8266 in the configuration of the NodeMCU, we will power the USB. So here, the potentiometer has to be connected from one end to the negative, and the other from the positive. The medium, which is the cursor, stays on in ADC 0, because this ESP only has a port that reads analog values.
