• Quando terei acesso às palestras e às tarefas?

  Ao se inscrever para um Certificado, você terá acesso a todos os vídeos, testes e tarefas de programação (se aplicável). Tarefas avaliadas pelos colegas apenas podem ser enviadas e avaliadas após o início da sessão. Caso escolha explorar o curso sem adquiri-lo, talvez você não consiga acessar certas tarefas.

• O que recebo ao adquirir o Certificado?

  Quando você adquire o Certificado, ganha acesso a todo o material do curso, incluindo avaliações com nota atribuída. Após concluir o curso, seu Certificado eletrônico será adicionado à sua página de Participações e você poderá imprimi-lo ou adicioná-lo ao seu perfil no LinkedIn. Se quiser apenas ler e assistir o conteúdo do curso, você poderá frequentá-lo como ouvinte sem custo.

• Qual é a política de reembolso?

• Existe algum auxílio financeiro disponível?

• What hardware is required to complete the course?

  The programming assignments require you to have a Raspberry Pi device - any model of Raspberry Pi with a 40 pin header. The course also uses the SenseHAT extension board, whilst it is preferable to have a SenseHat there is a simulator provided if you can't get a SenseHAT.

  You will need internet connectivity to download software, connect to the platform, develop and deploy your IoT solution.

  Your Rasberry Pi will need the latest Rasbian Jessie OS. This OS will be on a Micro SD Card. The recommended size of the SD card is 8GB but 4GB will do. Note that the learner kit comes with a preconfigured SD card.

  In order to setup the Micro SD card, you will need a computer with either a windows, apple or Linux OS. Since most computer do not have a micro SD port, you will need a Micro SD adapter or USB Micro SD card adapter. Your computer will also be used when working on the platform.

  To work on your Raspberry Pi, you will need an HDMI monitor or TV to work as the display for the Raspberry Pi (DVI monitor will also work). To connect the monitor to the Raspberry Pi you will need an HDMI cable (or a DVI to HDMI cable).

  Your Raspberry Pi needs a way to connect to the internet; either an Ethernet cable for connecting to the Router, or a USB WiFi dongle if you have wireless connectivity. Note that the Raspberry Pi 3 includes built-in WiFi

  A USB Keyboard and mouse.

  Your Raspberry Pi will also needs a 5V micro USB power supply i(This may be a phone charger for example)

  The element14 IoT Learner kit contains the Raspberry Pi, the pre-flashed SD card, a case and power supply : https://www.element14.com/community/docs/DOC-82034/l/element14-iot-learner-kit

• What prerequisite skills do I need to complete the course?

  This is an entry level course, but does assume you have basic programming skills. The assignments set use both Python and JavaScript programming languages, so some basic skill in these languages is required.

• What additional resources do I need for this course?

  The Server side code for the assignments will use the IBM Bluemix cloud platform, so you will need to sign up for a free account on that platform.

  When your 30-day trial expires, you can enter a credit card to keep using Bluemix. Bluemix has a set amount of free resources available to users who have registered with their credit card. If you stay within these free resources limits you will not incur any charges. This is a good idea if you are planning to take longer than 30 days to complete the course, or if you have an existing trial account that that is about to expire and you need longer time on the platform to complete the course.

• Where can I access the SenseHat simulator?

  If you don't have a Sense HAT, there is an additional Node-Red node that you can install that acts as the Sense HAT simulator. The simulator nodes have to be installed from the command line, into your node-red directory.

  On your Raspberry Pi, type these commands to install the node for simulation, and then restart node red:

  cd

  cd. node-red/

  npm install node-red-node-pi-sense-hat-simulator

  node-red-stop

  node-red-start

  The additional nodes will appear in your node-red pallet.

  The installed nodes act exactly the same as the real Sense HAT nodes in terms of the messages that you receive and the data you need to send to the nodes. But rather than talking to the real hardware, they just simulate that hardware.

  To allow you to control what the sensor's data is, there's also a web interface where you can control the environmental sensors. So you can set the value you want published.

  There's an output node for the simulated Sense HAT, and again, that will show you in the web interface what the state of the LED panel is. And that will match exactly what you'd see if you had a real Sense HAT.

  So when you do the assignment, if you have a real Sense HAT, you can use the real Sense HAT nodes.

  If you don't have a Sense HAT, you simply have to switch in the simulated node, and then use the web interface to help you test the various conditions for your application.

• I am in the middle of taking the course, and my IBM Bluemix trial has expired. What do I do now?

  If you have started a course that depends on the IBM Bluemix, and your trial has expired, you can continue taking the course on the same environment by providing your credit card information. To avoid being charged, close any application instances you are not using and pay attention to the usage of your environment details.

  Alternative, you can export any projects you are working on. Then, you can register for a new trial using a different email account, not used on IBM Bluemix before. Finally, import the projects to the new account.

  When exporting your projects, for Node-RED use the process used when submitting assignments (export flow form the old project, then import to the new project via clipboard). For Node.js you can redeploy the code to Bluemix using your new account credentials.

  If you have customized your GIT repository, or registered devices, migrating to a new environment will require you to redo those steps to reflect in the new environment.

• I am about to start the course, my IBM Bluemix trial has expired, how do I proceed with this course?

  If you already have an IBM Bluemix account, but your trial period has expired, you can always create a new account with a different email address.
