Understanding ADCs and Using the ADS1115 with Raspberry Pi (opens in new tab)

Understanding ADCs and Using the ADS1115 with Raspberry Pi Learn how analog signals become digital data, and how to connect the ADS1115 ADC to a Raspberry Pi for high-precision sensor measurements. Introduction One of the first surprises many Raspberry Pi users encounter is that the Pi has no built-in Analog-to-Digital Converter (ADC). This means that while the Raspberry Pi excels at digital communication, it cannot directly read analog sensors such as: Potentiometers Light sensors (LDRs) Gas...
