Circuit python read analog pin
WebThe Raspberry Pi doesn’t have any ADC pins—it doesn’t include an analog-to-digital converter. So, you need to convert the analog signal to a digital signal using an analog-to-digital-converter like the MCP3008 chip. Being able to read analog signals is useful to read varying voltage levels from a potentiometer or sensors, for example. WebMar 9, 2024 · An analog to digital converter (ADC) is a circuit that converts a continuous voltage value (analog) to a binary value (digital) that can be understood by a digital device which could then be used for digital computation. The Raspberry Pi Pico is built using an RP2040 microcontroller.
