In this installment, we cover what microcontrollers and microprocessors are, and when one might be favorable over the other, the basic features of an Arduino Uno, and basic programming workflow. The purpose of this is to show a designer the options available to them so that they can better assess how they might solve an engineering problem using electronics.

Next time, we look at how to finalize a payload with a printed circuit board designed in eagle and options for building a sturdy enclosure.

In this installment, we start developing a simple design by testing parts that satisfy a design. Along the way we demonstrate the use of a few types of digital interfaces that many sensors use, though there are many more out there. The sensors you use will depend on what experiment you're trying to do, basic recording of a flight, some experiment trigger at a particular altitude, and live video transmission would have different requirements from each other. Each one still usually has a strict weight limit, so efficiency is a must.

Next time, we put the pieces together and test it, and compare it to data from a real flight to see if these parts would do a good job.

In this video, we have a simplified third person look at how a launch works along with checking out some bits of footage from real launches. Next time, we'll dive into tools commonly used for development and some tools that I personally use to make things a little less of a headache. Then we'll get into how one of these payloads can be designed and built.
