im new to arduino and thinking to create a LED project.
im creating a LED project and i want to control 12 LED's. so i use two 7HC595 but problem i face is how can i only control 12 outputs ?
and i want to create multiple blink patterns with 12 LED, please be kind enough to provide blink patterns that i can modify and create different partners.
i have found many shift-out programs but i do not understand how to limit it to 12 outputs and create multiple blink patterns.
