| + | ====Raspberry Pi 3==== | ||
| + | The Raspberry Pi is a very small computer that has the characteristics of the computers people would use 15 years ago. | ||
| + | Raspberry Pi 3 characteristics: | ||
| + | * Broadcom BCM2837 SoC (4 ARM Cortex-A53); | ||
| + | * GB of RAM; | ||
| + | * integrated WiFi and BLE; | ||
| + | * HDMI port, an Ethernet port and four USB ports; | ||
| + | * several pins to use for electronics: | ||
| + | * two 5V pins; | ||
| + | * two 3.3V pins; | ||
| + | * 8 ground pins; | ||
| + | * 26 data pins; | ||
| + | * 1 PWM pin. | ||
| + | {{ :iot:labs:raspberry_pi3.png?500 |}} | ||
| + | The Raspberry Pi 3 has 26 GPIO soldered pins and 5 GPIO pins that you need to solder. These may be used to control electronics connected to the Raspberry Pi. Among the things that can be done are: | ||
| + | *light up LEDs; | ||
| + | *place buttons; | ||
| + | *use relays; | ||
| + | *control motors. | ||
| + | |||
| + | It is important to know how these pins can be accessed. For the Raspberry Pi, Wyliodrin uses the WiringPi pins layout described below. | ||

| + | |||
| + | ====Wyliodrin STUDIO==== | ||
| + | |||
| + | Wyliodrin STUDIO is a web-based platform for Internet of Things applications development. You are going to use this platform throughout the course for programming and controlling the Raspberry Pi. | ||
| + | |||
| + | In order to connect the Raspberry Pi to Wyliodrin STUDIO you will need an SD Card with minimum 4 GB (class 10 is recommended). You also need to assure the Raspberry Pi has a network connection or a serial connection to your computer (Ethernet or serial cable). | ||
| + | |||
| + | Setting up the board requires the following steps: | ||
| + | *Install Wyliodrin STUDIO; | ||
| + | *Download the Raspberry Pi SD Card Image; | ||
| + | *Write the image to an SD Card; | ||
| + | *Connect the board to your computer; | ||
| + | *Connect the board to Wyliodrin STUDIO | ||
| + | |||
| + | ===Install Wyliodrin STUDIO=== | ||
| + | Go to [[http://wyliodrin.studio|Wyliodrin STUDIO]]. There are two ways you can use WyliodrinSTUDIO, one is to download the application and the other one is to use it in the browser. | ||
| + | |||
| + | ===Set up the Raspberry Pi=== | ||
| + | In Wyliodrin STUDIO so to **Menu** and select **Documentation**. Choose Raspberry Pi and follow the steps.Connect the Raspberry Pi to the network via the Ethernet cable, then connect it to the platform. The default username is **pi** and the default password is **raspberry**. | ||
| + | |||
| + | Once the board is connected double click its name and give it a more suggestive name so you can recognize it. Then, go to **network manager** and set the WiFi credentials. | ||
| + | |||
| + | So you make sure nobody connects to your board, open the **Shell** tab and type **passwd**. Set another password for the user **pi**. | ||
| + | |||
| + | Disconnect the board from the Ethernet cable and now you will be able to connect to it via WiFi. | ||
| + | |||
| + | ====Exercises==== | ||
| + | - Create a new Python application that prints your name in the console. | ||
| + | - Load the **Music** example application, connect a speaker or headphones to the Raspberry Pi and make it sing. | ||
| + | - Install **Math.Pi** using the **package manager**. | ||
| + | - Create a Python application that prints your name every one second. | ||
| + | - Run the previously created application. Using the **task manager** identify the corresponding task and kill it. | ||
