Complete the code in a way that LED blinks every 2 seconds.2. Change the startTimer method to accept a double value called timerFrequency, which representsthe frequency of the timer. Change the startTimer function so that it uses the value of this parameterto calculate and set the correct values for the OCRx and TCCRx registers.3. Use the potentiometer sensor connect to pin A4 to enable users to configure the timer frequency.
