Electrical Engineering Assume we are using a microcontroller that is only compatiable with the C language. Given an input of some AC sinusoidal voltage wave, create a function to calculate the frequency of the input wave if the internal instruction clock is running at a frequency of 1 Mhz. Assume we have a function called "Volts()" with void parameter that returns the voltage that is read by the microcontroller at that specific time.
