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

1. Create a function that takes as an input a floating point number between 0 and 1. Based on the floating point value, the function needs to set the appropriate percent value in the OCR2B register. For example, if the input value is 0.6, then the count should be 60% of TOP. 2. Write a program that outputs a 2 kHz, 0 to 5 V saw-tooth PWM signal. Note that DDRx still has to be set to an output for the PWM port pin Tip: You may use the function you used in question 1. You can use either micros() to see how much time has passed from a previous call. You may also use delayMicroseconds() to force a specific delay. 1.
