Plan Your Experiment Design Now that you’ve thought about possible experiment ideas. We can think about how we actually make those experiments work. On the flight, there will not be anyone to press start on the experiment. We can use microcontrollers to automate them. Let’s learn how to take your experiment idea and put it to work in the sky.
First, we will learn about microcontrollers and helpful hardware components.
Next, we will use a hardware component menu to plan out an experiment design.

What is a Microcontroller?● Embedded programmable computers● Examples include:
○ Arduino■ Uno■ Mini■ Zero
○ Adafruit Circuit Playground○ BBC Micro:bit○ Sparkfun Redboard○ ESP32 Boards○ Itsy Bitsy○ Many more!
● Development boards are designed to quickly develop hardware prototypes!

What is Code?● Code is the language we use to give
instructions to microcontrollers (and computers in general)
● Computers only understand binary○ 0100011101000101011011
● Humans need language and code bridges this gap

A closer look● Microcontrollers like Adafruit Circuit
Playground or BBC Micro:Bit are learning boards with a lot of extra hardware built-in○ Buttons○ Lights○ Sensors
● These types of boards are good for learning to code, classroom demonstration, and “fast prototyping”

A closer look● Microcontrollers like Arduino or
Adafruit Metro provide input and output (I/O) with little or no additional hardware
● These types are generally used to build your own systems and prototypes

Microcontrollers are everywhere!These small embedded computers are increasingly common in everyday consumer products.● “Smart” Devices● “Internet of Things”● Digital Thermostats● Remote Controls● Garage Door Openers● Automated Devices● Electronic Toys● Electronic Games

Hardware and Software Ecosystems There are different hardware and software ecosystems for each microcontroller. When choosing a microcontroller it is important to be aware of what coding language it uses as well as what components are compatible with it.
Let’s take a look at what boards are compatible with what software (coding language).

What does this have to to do with Science?Because microcontrollers can be programmed to automate certain tasks, scientists and engineers use them to create instruments that automatically take measurements and record data… like in space, on the Moon, and on Mars!
