In this fourth part of the Beyond Arduino series, you'll learn many techniques to produce more efficient and professional embedded applications. It's time to leave the toy programs behind.

You'll learn how to handle memory-attached hardware registers properly, how to perform bitwise manipulation of data, how to handle interrupts on your microcontroller development platform, and many other techniques which you aren't always aware of because of the immense body of elements that conceal the details in many beginner platforms, like the Arduino, for the sake of simplicity.

You'll also learn how to deal with very basic, typically 8-bit, microcontrollers that don't have a Floating Point Unit and still write code that gets the job done in the best way possible even with the limited resources available. 

After grasping this knowledge, we expect you to think differently when designing your embedded applications in the future. By adding these best practices to your bag of tricks, you'll get one step closer to making embedded applications like a professional, and hopefully you'll feel less like a beginner.
