This is my first go with the Arduino and my first post here on the forum! I have quite a bit to learn about electronics. The nice thing is that the Arduino feels like legos for electronics. I find that it is very easy and inviting to learn as well as fun and rewarding.
I ordered a starter kit and was able to assemble a small binary counter given the items I had. I'd like to turn this into a binary clock, perhaps with an alarm.
Presently it counts to 31 as I only have 5 LEDS and buzzes when it hits 31. You can control the speed with the potentiometer.

Criticism are welcome! I am here to learn. :)
