Problem 5: Consider the following flowchart of a program that controls the brightness of an LED: START Decrease Brightness by 10% OR Stay at Minimum Brightness of 0% Press Button2 Press Button2 Press Any Button LED On LED On At 50% Brightness Desired Brightness Press Button1 Increase Brightness by 10% OR Press Button1 Stay at Maximum Brightness of 100% (a) Program the first two steps shown in the diagram above. When the Launchpad starts, a red LED is off. If either of the Launchpad buttons is pressed, the red LED turns on at 50% brightness. Use PWM (pulse width modulation) to control the brightness of the LED. The signal driving the LED should have a high enough frequency that the LED does not appear to flicker. (b) Add the remaining steps shown in the diagram above to the program you wrote in Part A. When button 1 is pressed, the brightness of the red LED increases by 10%. If the brightness of the LED is already 100%, pressing button 1 does not increase the LED brightness any further. When button 2 is pressed, the brightness of the LED decreases by 10%. If the brightness of the LED is already 0%, pressing button 2 does not decrease the LED brightness any further.
