Difficulty in Arduino programming on LED -


im working on arduino proramming have 1 led off on next one.. 16 leds tgt , im using shift register mc74hc595an aka 595 register. im finding difficult code them myself still learning how programme arduino. having code or work out on code share me please? form of appreciated! thank you!

here code did doesnt seem working.

    const int button0pin = 15;     const int button1pin = 1;     const int button2pin = 2;     const int button3pin = 3;     const int button4pin = 4;     const int button5pin = 5;     const int button6pin = 6;     const int button7pin = 7;        void setup() {       // put setup code here, run once:     pinmode(button0pin, output);     pinmode(button1pin, output);     pinmode(button2pin, output);     pinmode(button3pin, output);     pinmode(button4pin, output);     pinmode(button5pin, output);     pinmode(button6pin, output);     pinmode(button7pin, output);     pinmode(14, input);      serial.begin(9600);      }      void loop() {       // put main code here, run repeatedly:        digitalwrite(button0pin, 0);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     delay(5000);      digitalwrite(button0pin, 0);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 1);     delay(5000);      digitalwrite(button0pin, 0);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 1);     digitalwrite(button2pin, 0);     delay(5000);      digitalwrite(button0pin, 0);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 1);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     delay(5000);      digitalwrite(button0pin, 0);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 1);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     delay(5000);      digitalwrite(button0pin, 0);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 1);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     delay(5000);      digitalwrite(button0pin, 0);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 1);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     delay(5000);      digitalwrite(button0pin, 0);     digitalwrite(button1pin, 1);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     delay(5000);      digitalwrite(button0pin, 1);     digitalwrite(button1pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     digitalwrite(button2pin, 0);     delay(5000);     }

so, clear here, initializing pin 14 receive input, never use in main loop check if getting input.

to make life easier, consider naming pins shorter names. instead of "button0pin" how "b0"?

also, may want try using loop instead of doing (writing out separate blocks of code, each output of 1 pin @ different spot)

you can read arduino reference guides (i read every time i'm programming) here: https://www.arduino.cc/en/reference/homepage

and link: https://electronics.stackexchange.com/questions/17975/arduino-uno-light-leds-right-to-left-and-then-reversed may similar loop you're needing.

hope helped, @ least little bit.

Google AdWords and AdSense - A Dynamic Small Business Marketing Duo

Unless you have been living under a rock for the last year or so, you probably know that Google has become the king of the search engine hill. There are many reasons for this but number one in my opinion is that above all else they put value on content. Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners. Here is an example - those ads in the box on the right of the page are delivered by Google and are matched to the content
