Now it is time to modify pwmled2. Your code will need toaccomplish the following:
• Set duty for PWM1 to 90%.
• Set duty for PWM2 to 10%.
• Set the sleep(1) function so it sleeps for 1 second.
• Set duty for PWM1 to 0%.
• Set duty for PWM2 to 90%.
• Create your code in a loop.
Note that it will be difficult to determine the PWM values fromthe LEDs due to the differences between the yellow and green LEDs.The yellow LED is much brighter than the green LED. The green LEDat 10% appears as though it is turned off. Also, the PWM_setDuty()function does not take percentages. Thus the functionPWM_setDuty(pwm1, 90) will not work. Instead you need to calculatethe value (90% of the period).
I WILL ONLY UPVOTE IF YOUR ANSWER IS RELEVENT ANDCORRECT.
