Using C programming and this code as a base. Write a code that uses pulse modulation to generate a signal with a period of 1000 ms, and a 50% duty cycle for 5 seconds. This should cause the LED to flash on and off with equal time, once a second, for 5 seconds. If you enter a period of 1000 ms, and a 90% duty cycle for 5 seconds, it should cause the LED to flash on and off, once a second for 5 seconds, where it is on for 90% of the time. If you enter a period of 25 ms, and a 25% duty cycle for 5 seconds, it should cause the LED to appear to be on constantly at a quarter of its normal brightness. ** note this code is being run on a raspberry pi using geany.
