This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
This may be a loosely worded message but, I can't give more information. I am getting a e-props-correct.4: error. And some how I just can't solve it. Any ideas to fix the problem?
