What is the Arduino platform?
The DIY Revolution
We live in a unique time where we have access to resources that allow us to create our own solutions and inventions. The DIY revolution is composed of hobbyists, tinkerers and inventors who would rather craft their own projects than let someone do it for them.
A Computer for the Physical World
The Arduino in your hand (or on your desk) is your development platform. It is capable of taking inputs (such as the push of a button or a reading from a light sensor) and interpreting that information to control various outputs (like a blinking LED light or an electric motor).
That’s where the term “physical computing” is born - this board is capable of taking the world of electronics and relating it to the physical world in a real and tangible way. Trust us - this will all make more sense soon.
The Uno is a great choice for your first Arduino. It’s got everything you need to get started, and nothing you don’t. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a USB connection, a power jack, a reset button and more. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. Check out our What is an Arduino? tutorial, to learn more about Arduino.
Connect your Arduino Uno R3 to your Computer
Use the USB cable provided in the SIK kit to connect the Arduino Uno to one of your computer’s USB inputs.
Download the Arduino IDE
In order to get your Arduino Uno R3 up and running, you’ll need to download the newest version of the Arduino software first from www.arduino.cc (it’s free and open source!). This software, known as the Arduino IDE, will allow you to program the board to do exactly what you want. It’s like a word processor for writing programs. With an internet-capable computer, open up your favorite browser and go to Arduino download page.
Check out our Installing Arduino IDE tutorial, to see in detail on how to install the Arduino IDE on your computer.
Getting Started in the Arduino IDE
Now, it’s finally time to open up the Arduino software. You’ll be presented with a window that looks a little something like this:
- Verify: Compiles and approves your code. It will catch errors in syntax (like missing semi-colons or parenthesis).
- Upload: Sends your code to the RedBoard. When you click it, you should see the lights on your board blink rapidly.
- New: This buttons opens up a new code window tab.
- Open: This button will let you open up an existing sketch.
- Save: This saves the currently active sketch.
- Serial Monitor: This will open a window that displays any serial information your RedBoard is transmitting. It is very useful for debugging.
- Sketch Name: This shows the name of the sketch you are currently working on.
- Code Area: This is the area where you compose the code for your sketch.
- Message Area: This is where the IDE tells you if there were any errors in your code.
- Text Console: The text console shows complete error messages. When debugging, the text console is very useful.
- Board and Serial Port: Shows you what board and the serial port selections
Before we can start jumping into the experiments, there are a couple adjustments we need to make.
Select your board: Arduino Uno
This step is required to tell the Arduino IDE which of the many Arduino boards we have. Go up to the Tools menu. Then hover over Board and make sure Arduino Uno is selected.
Select a Serial Port
Next up we need to tell the Arduino IDE which of our computer’s serial ports the Arduino Uno R3 is connected to. For this, again go up to Tools, then hover over Port (Serial Port in older Arduino versions) and select your Arduino Uno R3’s serial port.
Window Users: This is likely to be com3 or higher (COM1 and COM2 are usually reserved for hardware serial ports). To find out, you can disconnect your Arduino Uno R3 and re-open the menu; the entry that disappears should be the Arduino Uno R3. Reconnect the board and select that serial port.
Arduino IDE version 1.6.1 serial ports is under “Port.” In older versions it is under “Serial Port”
Mac Users: Select the serial device of the Arduino Uno R3 from the Tools, then hover over Port. (You will be hovering over Serial Port if you have older versions of the Arduino IDE) On the Mac, this should be something with /dev/tty.usbmodem or /dev/tty.usbserial in it.
Arduino IDE version 1.6.1 serial ports is under “Port.”
Linux Users: Please visit the Arduino Learning Linux section, to learn more about Arduino on Linux.
