The reason I started this project is because I recently had a bad experience flying a quadcopter too far from me until I was not able to distinguish if the quad was facing me or not. It does not require much distance before a quadcopter looks like a tiny black dot in the sky. Basically, I lost orientation of the quad and I had to land way too far from my takeoff location.

Please note that csvplot source code is now moved to GitHub. Source code can be downloaded from the project’s GitHub page.

The following article is about my simplest library that I wrote for the arduino: SoftTimers. The SoftTimers arduino library allows one to properly time multiple events and know when each “timer” expires meaning that an action is required.
