What is Physical Computing?
Physical Computing, or Pcomp for short, refers to the practice of using a computer to interfacing with the natural physical world. The process can include receiving data from the natural world and/or creating an output outside of the computer that effects the world. We will learn how to use microcontrollers as an intermediary between the physical world and your computer.
Intro to Arduino, Welcome to the club
The Arduino is a wonderful prototyping platform for a number of reasons. The Arduino uses an open source hardware business model. What this means is that they give away for free exactly how to make their product and they also allow you to take those plans and make their product and sell it, I believe as long as you do the same. This breeds an environment where everyone shares and everyone succeeds together growing together as the collective knowledge grows. This means that there are tons of code lying around the web waiting for you to search for them and throw them onto your arduino, making simple work of simple projects. This also means that many people have designed add-ons to the original platform that interface easily and add a great deal of functionality. So welcome to the club, have fun and enjoy the life.
Intro to Arduino, Welcome to the club
There are many things you can do with the Arduino platform. Here are few of my favorites:
Botanicalls - allows plants to call their owners to tell them they need water or nutrients
SIMbaLink - smart solar harvesting
Intersects the Plane - robotic light sculpture
How to Install Arduino
The people at Arduino have put together a wonderful intro to the arduino for any of the major platforms. Check out the link and follow along to install get started when you get back to your house.
Arduino web resources
There are a ton of web resources available for the Arduino. Here are a few of my go to places to look for help:
The Arduino website includes an entire run down of the arduino language.
The website also includes a ton on how to get started including examples, foundations, and links to other resources.
Along with the code that comes with Arduino, you can use code people have created to work with Arduino. These are called libraries and they can be found here. Most libraries will have links to more information on how to use the code they provide.
While you might think that you have a unique idea, this is almost certainly not the case. Check the forums at Arduino (old forum) to see if anyone has already solved the problem you are trying to figure out.

What are our materials
Here is a run down of the parts in the kit:
1 Arduino Uno
1 breadboard
1 USB cable (A to B)
2 momentary(or biased) switches
2 potentiometers
1 photoresistor
5 red LEDs
3 superbrite LEDs
5 100 ohm resistors
5 1000 ohm resistors
5 10000 ohm resistors
1 bundle of jumper wires
Lets make something blink!
For startes we are going to use the basic Arduino introduction sketch, the blinking LED. Now while this is a basic sketch, it is an amazing experience, I remember my first blinking LED well. Lets jump to the Arduino site to take a look at the sketch.
The difference between input and output
This is pretty simple, inputs are values and processes associated with things coming into the Arduino, while an output is a value that is sent out from the Arduino. Human inputs are our five senses and our outputs are using our body in any way to effect the outside world for example talking.
I have been a herpes carrier for 2 years and I tried every possible means of curing but all of no useful until I saw a health promotion on a herbalist from West Africa who prepares herbal medicines to cure all sorts of diseases including #HSV and many others sickness but look at me today am very much happy and healthy, I'm telling you today don't lose hope keep trying God is with you, If you needs Dr.Chala help contact him on his email dr.chalaherbalhome@gmail.com or you can visit his website on http://drchalaherbalhome.godaddysites.com or https://mywa.link/dr.chalaherbalhome
