Question about LED matrix in general - how odes it work ??? Answered
Hi ... I had a look at this instructable www.instructables.com/id/LED-matrix-using-shift-registers/ and there is this picture with the schematic how to create the matrix www.instructables.com/files/deriv/FSW/VO3F/FHAVXXA0/FSWVO3FFHAVXXA0.MEDIUM.jpg
My question is how does it work, because I can't understand it. I'll give an example :
Imagine, you turn on 4 leds : LED1, LED8, LED57, LED64. And my question is, how are you going to turn OFF just ONE LED without affecting other LED's ???
When I'm looking at the schematic and I'm trying to TURN OFF LED 1 ... well if I turn off the ROW1 then I automatically switch off the LED8 as well...or NOT ???
Am I missing something or am I right ???
