Now it is time to modify pwmled$2.$ Your code will need to accomplish the following:

Set duty for PWM$1$ to $90\%.$

Set duty for PWM$2$ to $10\%.$

Set the sleep$(1)$ function so it sleeps for $1$ second.

Set duty for PWM$1$ to $0\%.$

Set duty for PWM$2$ to $90\%.$

Create your code in a loop.

Note that it will be difficult to determine the PWM values from the LEDs due to the differences between the yellow and green LEDs. The yellow LED is much brighter than the green LED. The green LED at $10\%$ appears as though it is turned off. Also, the PWM$\_$setDuty$()$ function does not take percentages. Thus the function PWM$\_$setDuty $($pwm$1,90)$ will not work. Instead you need to calculate the value $(90\%$ of the period$).$
