Question

How many analog pins are there on an Arduino Uno board?
1) 5
2) 6
3) 7
4) 8

Answer 1

The Arduino Uno has 6 analog input pins, labeled A0 through A5, used for reading analog voltages and converting them to digital values.

Step-by-step explanation:

The Arduino Uno board is equipped with 6 analog input pins. These analog pins are labeled A0 through A5 and can be used to read analog voltages. The Arduino Uno uses these pins to convert input voltages ranging from 0 to 5 volts into digital values between 0 and 1023, which allows the microcontroller to process analog signals from various sensors.
