Step 1

What is the resolution of the Analog to Digital Converter in your Arduino Board? The resolution of the Analog to Digital Converter (ADC) in the Arduino Uno board is 10 bits. This means that it can represent analog voltages with a resolution of 2^10, which is 1024 Show more…

Text: Microcontroller Q1. What is the resolution of the Analog to Digital Converter in your Arduino Board? Q2. Show your calculation of converting the decimal reading of LDR into Voltage. Q3. What happens if you swap the locations of the resistor and the LDR in the voltage divider setup?
