Problem
An embedded system is used to generate a PWM signal through an overflow interrupt signal from timer/counter 0. This system uses the ATmega32 microcontroller running a clock frequency of 8MHz and a prescaler equals to 64. The output signal has a frequency of 5 Hz at pin 1 from port B. Construct the C code needed to design this embedded system. Include all the required calculations.
The response should include a reference list. Using double-space, Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
