Write the code using embedded C for an arduino uno. Please comment all lines in code and explain

4. Determine the appropriate bit settings for ADCSRA, ADCSRB, ADMUX,and DIDRO to read an analog input using the following specific details use a pre-scale division of 16, use the internal 5 V VREF use right justification, use ADC channel 5. 5. Create a function that initializes the ADC sub-system based on the values determined in In Problem 4. 4.
