Re: Single LED resistor calculator

Practically I've used 100k, 1/2W resistor with a LED. Current flow is too small, but it's suitable when you use LED for indication.

Re: Make LED matrix array using a single microcontroller

Think about it as this. You TV refreshes the display 25 times per second. With two fields, it is like 50 fields per second. With a microcontroller, How fast you think you can refresh these LED displays ? That's how this scanning method work. Though it can be logically thought as drawing to one disp...
