The H-bridge (steps: 0)

I am going to go ahead and get this tutorial started, though it will likely be a work in progress.

The H-bridge is an interesting concept that is the digital equivalent to a set of train tracks switching to make a train go a different direction when needed. The H-bridge is a set of 4 switches (simple switches), aligned so that when turned on in opposite pairs they will produce different results, like changing the direction of a DC motor. You can go quite deep into this theory...

Pulse Width Modulation (steps: 1)

This tutorial will attempt to simply a commonly used digital output method that might be a bit confusing, PWM. Firstly we must understand that pulse width modulation is a type of digital signal so it can only be either 0v when LOW or 5v when HIGH (on an Arduino). The tricky part is that the digital signal is switching from LOW to HIGH really quickly, usually too fast for you to notice - the result however is that of an Analog output signal and can appear to be anywhere between 0v and 5v. T...

Beginning Electronics (steps: 1)

*Under Construction*

Before we get into electronics, we should start with electricity. Why should you learn about electricity? Because it is dangerous and it can hurt you but also awesome... so you should find out what you shouldn't do before you go exploring the wonderful world of electronics. I will try to devise a set of 10 steps that you can (safely) follow to get you started exploring in the right direction.

Electricity is simply heat that has been har...
