Description
Running out of output pins on your PIC microcontroller? This course gives you the exact tools to overcome that bottleneck.
Whether you're working on LED matrices, control panels, or embedded automation systems, you'll need to control more outputs than your microcontroller natively supports. In this course, you'll learn how to expand PIC output pins using hardware like 74HC595 shift registers and multiplexers, plus how to write optimized C code for smooth, synchronized control.
This course focuses on real-world implementation-from circuit design to firmware logic-giving you the flexibility to build bigger, more capable PIC-based systems without changing microcontrollers.

FAQ
Q: Do I need to use the 74HC595 only?
A: We use it as a core example, but you can apply the same principles to other serial-to-parallel ICs.
Q: Will this work with any PIC microcontroller?
A: Yes, though the course focuses on the PIC16F series. The logic works across most mid-range PICs.
Q: Is hardware mandatory?
A: It's highly recommended for hands-on practice, but simulations can be used to follow along.
Q: What if I need help?
A: You'll have access to Q&A support and a course community for troubleshooting.
Q: Do I get a certificate?
A: Yes, a Certificate of Completion is issued once you finish the course.
