In this example we connect an ADS1115 analog-to-digital converters to a Raspberry Pi. Lets look at the ADS1115. The ADS1115 is a precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in an ultra-small, leadless, X2QFN-10 package, and a VSSOP-10 package. The ADS1115 incorporates a low-drift…
