Arduino Binary Counter

In my second project I look at creating a binary counter with LEDs to illustrate the counting process. The function bitRead() is very useful for this as it takes any integer value and reads it as a binary number. Each bit in the binary number is used to change the lights on or off.

Thanks for this,
I made a binary thermometer measuring up to 31 degrees, and was just about to type in 31 if statements and 31 functions, each showing which led's to light up, when I spotted your vid. Saved me lots of typing :)

That was a great project. Thanks for posting the video. I was trying to implement it by also using an array too, but I was going to do the math - as it is explained to us when we learned to convert a decimal number to binary - but that was getting a bit messy. I'm glad that I found your project and that you use functions readily available to do the conversion.

HI, thank you very much for the wonderful tutorial, can you please post the code you used as it is difficult to see on the screen and thus difficult for me to follow what you are talking about.
Thank you
