A: An Arduino uno board has a 10-bit ADC attached to its analog input pins. Every analog input voltage is converted into a digital number bythe ADC which is attached to the board. If the analog pin is connected to a light-dependent resistor and a fixed resistor combination and theoutput voltage provided by the combination is 2.75V. If the Arduino board is working at a 5V supply, then find the 10-bit digital codecorresponding to the given input voltage. (Just write the 10-bit digital number)Output =
Solution
The Arduino Uno board uses a 10-bit ADC, which means it can represent the input voltage with a range of values from 0 to 1023 (2^10 - 1). The range of input voltages is from 0V to the supply voltage, which in this case is 5V.
The digital value corresponding to a given analog voltage can be calculated using the formula:
Digital Value = (Analog Voltage / Supply Voltage) * 1023
Substituting the given values into the formula:
Digital Value = (2.75V / 5V) * 1023 ≈ 563
So, the 10-bit digital code corresponding to the given input voltage of 2.75V is approximately 563.
