Note: For all lab experiments you can either use the Arduino Uno R3 available in the Lab or bring your own Arduino. Lab computers will have all necessary software (Microchip Studio, AVRDUDE, Arduino Software.) You can also use your own laptop. For this lab, you cannot use any Arduino function. Experiment : Write a C program to generate a Pulse Width Modulation (PWM) signal on PB2 with the following characteristics: Frequency of the PWM: 3KHz. Duty cycle varies by 20% every five seconds, starting from 20%, e.g., it starts with duty cycle of 20% and stays at this level for five seconds, then duty cycle increases to 40% and stays at this level for five seconds, etc., until duty cycle reaches 100%. After five seconds at 100% duty cycle, it goes back to 20% duty cycle and the entire sequence repeats. You can make use of the delay function _dclaxms and/or delax uso).
