Qus : The analogRead method in Arduino UNO returns value range
QusArduino UNO में analogRead() फंक्शन की वैल्यू कहा से कहा तक होती है
A. 0-255 B. 0-511
C. 0-1023 D. 0-4095
Solution
C. 0-1023
Explanation
The analogRead method in an Arduino UNO returns a value in the range of 0 to 1023. This range corresponds to the analog input voltage between 0 and 5 volts, giving a resolution of approximately 4.9 millivolts per unit (5V/1024 units).
