Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V or 3.3V) into integer values between 0 and 1023, the Adafruit ADS1115 extends it to a 16 bit analog to digital converter (2.0V to 5.5V) which is better for the low voltage inputs given by a geophone in order to read vibrations. The ADS1115 is connected to Analog pin 36 and is defined as GPI36 or ADC_0. When running the comparator sketch I get accurate readings from the geophone ( which is directly connected to the ADS1115. The only issue I am having is getting the Heltec LoRa32(V2) to only send data when the geophone detects vibrations.
