Guide V1.0 Arduino IDE (Integrated Development Environment) Introduction The Arduino Software (IDE) is easy-to-use for beginners, yet flexible enough for advanced users to take advantage of as well. For teachers, it's conveniently based on the Processing programming environment, so students learning to program in that environment will be familiar with how the Arduino IDE works.
Guide V1.0 Choose the components to install and click “next” button. Choose the installation directory. The process will extract and install all the required files to execute properly the Arduino Software (IDE) Step 2: Get an Uno R3 and USB cable In this tutorial, you're using an Uno R3. You also need a standard USB cable (A plug to B plug): the kind you would connect to a USB printer, for example. Email: keen@elecrow.com Web: www.elecrow.
Guide V1.0 Step 3: Connect the board The USB connection with the PC is necessary to program the board and not just to power it up. The Uno and Mega automatically draw power from either the USB or an external power supply. Connect the board to your computer using the USB cable. The green power LED (labelled PWR) should go on. Step 4: Open Lesson 1: LED blink Open the LED blink example sketch: CD > For Arduino>Demo Code>Lesson1-LED_bink>led_blink. Email: keen@elecrow.com Web: www.elecrow.

Guide V1.0 Selecting an Arduino/Genuino Uno. Email: keen@elecrow.com Web: www.elecrow.
Guide V1.0 Step 6: Select your serial port Select the serial device of the board from the Tools | Serial Port menu. This is likely to be COM3 or higher (COM1 andCOM2 are usually reserved for hardware serial ports). To find out, you can disconnect your board and re-open the menu; the entry that disappears should be the Arduino board. Reconnect the board and select that serial port. Step 7: Upload the program Now, simply click the "Upload" button in the environment.
Guide V1.0 Step 8: Result A few seconds after the upload finishes, you should see the pin 13 (L) LED on the board start to blink (in orange). If it does, congratulations! You've gotten Arduino up-andrunning. Arduino interface introduction A B C D E F Email: keen@elecrow.com Web: www.elecrow.
