There are no comments for now.

1. Analog Input means Arduino reads:
a) 0 or 1 only b) 0 to 1023 c) ON or OFF only
2. The Potentiometer helps us to:
a) Change the input value b) Make sound c) Give power to Arduino
3. The middle pin of the Potentiometer is connected to:
a) Arduino Analog Pin b) Arduino GND only c) LED short leg
4. What happens to the value when we turn the Potentiometer?
a) Change b) Stay the same c) Turn off Arduino
5. Which pin do we use to read the Potentiometer value?
a) Analog input pin b) GND pin c) VIN pin
6. The command used to read the Potentiometer value is:
a) digital Read b) analog Read c) digital Write
7. The Potentiometer can give Arduino:
a) Many different values b) Only 0 and 1 c) No values
8. A student connected the Potentiometer signal pin to A0, but the code reads A1. What will happen?
a) The reading may be wrong b) The LED will become brighter automatically c) Arduino will stop working
9. Why do we use a variable like Pot Value in the code?
a) To store the value read from the Potentiometer b) To protect the LED c) To give power to Arduino
10. In the code, if Pot Value > 500 but the LED is set to LOW, what will happen?
a) The LED will turn ON b) The LED will turn OFF c) The LED will blink automatically
