First project, powering an IC
In your circuit diagram is the first voltage regulator a 5V version and the second a 3.3V. 

If you use a 7809 (9V) for the first and a 7805 (5V) for the second voltage regulator it should work fine. But have in mind the power consumption of the LED strip that the 7809 can handle it.

I don't know the PWM circuit with the 74AC14. If he post it it should work. But in your circuit you use 1N4001 diodes which is not necessary. They can handle higher current compare with the 1N914. Use the 1N914 or 1N4148 it is equivalent. Datasheet
