I am working on an proj, and nt an expert in programming.,
here is my problem i am facing,
-> need to individually control 120 LEDs
-> for which thought of using shift register 74HC595, bt d thing is i am nt able to understand d sample prog given in tutorial,
need help understanding more abt shiftOut, bitWrite, lowByte , highByte.
-> if possible, help me out in program for controlling d 120 LEDs., d sequence in which d LED needs to gt HIGH depends on d alphabet dey send in through serial monitor and d LEDs to be lit up are hard-coded in d code; a comparison is done wit d character sent via serial monitor and d hard-coded sequence is used for illuminating d LEDs...
and if thro serial monitor 'A' is sent den, will do a comparison and send d value pertaining to byte A, and corresponding LEDs will b illuminated., d reason y 120 is it will b accepting a string nt just a character...
What is the point of providing an efficient method if I quote:
am nt able to understand d sample prog given in tutorial
I suggest you hook up a single register, some led's, and resistors, and stick to that hardware set up until you can make sense of the shiftOut function and the tutorial/sample reference.
Reading the datasheet may help, you-tube videos are in abundance.
wow wow., i am not a expert and all., a newbie., just wanted to learn few stuffs., and asked for help..
i read through the tutorials and reference pages and face problems while using shift-register., it would be helpful if i could get a solution to my problem.
