LED Roulette Wearable Crochet

After power on, it starts a LED chase. Turn on one LED and wait a while, than turn it off and turn it on the next neighbor LED and so on. After the 10-th LED is off the cycle starts again. With time the chase will be slower, and it will stop at a random LED. After the winning LED is on it will make a LED blinking show, and start the roulette mode again.
