|
False
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -The Pi does not include a hardware analog-to-digital converter, but an external ADC (such as the MCP3008) can be used, along with some SPI code in Python to read external analog devices.
Detailed explanation-2: -The Raspberry Pi’s GPIO pins are digital pins, so you can only set outputs to high or low, or read inputs as high or low. However, using an ADC chip (Analogue-to-Digital converter), you can read the value of analogue input devices such as potentiometers.
Detailed explanation-3: -The ADC Pi Zero is an 8 channel 17 bit analogue to digital converter designed to work with the Raspberry Pi Zero. The ADC Pi Zero is based on two Microchip MCP3424 A/D converters each containing 4 analogue inputs.
