Over the past couple years I have been compiling the Arduino learning links, reference pages, and resources, that I have found the most useful for my learning. I keep this list updated, and regularly add to it. The list is found at the bottom of my article titled "The Power of Arduino." Go there, scroll to the bottom, and you'll find the list.

It currently contains the following sections:

Intro:

I've been wondering how to put hyperlinks in blog comments for quite some time now, so I finally did a little research to find out how! Read on.

If you'd like to make your next comments at the bottom of an article a little more fancy, with hyperlinks, bold, or italics, for example, here's how!  Feel free to practice your new skills in the comments below this article too, as scratch space to test your syntax.

The following commands are accepted in Google Blogger comments:

Question I Just Received:
-from "Lakshman

"Hi Gabriel.
I am referring to your post http://electricrcaircraftguy.blogspot.sg/2014/10/restoring-over-discharged-LiPos.html#.VNXv9mSUcp0.

I accidentally discharged my battery to 2.8v/cell today due to a faulty lipo alarm. It did not go off at 3.6V while flying my tricopter and within a minute or so, the voltage dropped to 2.8v/cell. I recharged it back to 3.8v storage at 0.2A without any issues. This was before I read that article.

How do I quantify the amount of damage done to the battery pack? I usually stop flying at or before ~80% discharge. Will it be a lousier battery after this incident?

Thank you."

Here's what I had to say...

Though I first posted this article on my Instructables page, I decided to update it and repost it on my main website here in order to keep my articles more consolidated and easily maintained by myself.  From this point on, I will keep the most up-to-date version of this article right here, instead of on my Instructables page, so if you want the latest info, read here.  Don't forget to subscribe to receive an email whenever I post something new by clicking the subscribe link at the top-right of this page!  I will never use your email addresses for spam.

A LiPo that self-discharged, while in my plane, hanging overnight in a tree. :(

Intro:

LiPo batteries should never be discharged below 3.0V/cell, or they may be permanently damaged.  Many chargers don't even allow you to charge a LiPo battery that is below 2.5V/cell.  So, if you accidentally run your plane/car too long, you don't have your low voltage cutoff set properly in the ESC (Electronic Speed Controller), or you leave the power switch on, forget to unplug the LiPo, get your plane stuck overnight in a tree (the same tree, three separate times, for foolishly flying in areas too small because you are too excited to fly and it's almost dark), etc. etc., you may find yourself in a situation where you've discharged your LiPo down well below 3.0V/cell.  What do you do?

Many people toss the LiPos in the trash.  I don't.  I restore them.  Here's how.

20141031: major bug fix; added multi-button support with a new 5-button-reader example!
20140531: I just released this library to GitHub!

Summary:

I wanted a simple and universal, yet very powerful & reliable library to read a button or switch in such a way that I can easily implement toggled actions and momentary actions, know the true, debounced state of a button or switch at any given time, and specify whether I want an action to take place when the button is *pressed* or *released.* This library makes implementing all of these things easy for me, and I now use it on all of my projects that require reading a button or switch, so I wanted to share it with others. Hopefully you find it useful too. Check out the included examples.  

This code is an elaboration of, and library form of, the main Arduino-sponsored "Debounce" example found here.  Thanks to David A. Mellis, Limor Fried (LadyAda), and Mike Walters for writing that excellent and well-thought-out example code.

Download the eRCaGuy_ButtonReader Library here --> then go to "Download ZIP" at the bottom of the right-hand pane.  See the Readme file right here too if you need help installing Arduino libraries.
