In this tutorial I will show you how to blink 1-12 leds. I have designed the code so that you can insert 1-12 leds but you can edit it so that you can insert 13 or more.

Step 1: Materials

For this project you will need:
Arduino board
1-12 leds (im using 10)
usb adapter
solderless breadboard

<p>I uploaded your code to my HSS (Halloween Scaring System)</p><p>Here are the results</p>
<p>thanks, it worked great</p>
When I was a kid and made blinking LED projects I used SSI TTL ICs, usually there was a 555 timer involved too. How times have changed ...
yeah, everythings alot more simple but the things you can do are amazing
