Thank You, Dear Maker!

If you are reading this QUICK START GUIDE you have probably purchased our BigClown IoT Kit. If not, go shopping to do so :)

Once again THANK YOU for being our supporter, we really appreciate this.

BigClown is not just about the hardware but it comes with full documentation, tutorials, software tools and most importantly - it comes with the extensive technical support. So don't hesitate to use one of these channels In case you run in troubles or if anything is not clear to you:

Be Inspired

It's always hard to build something without an inspiration. We motivate our makers to share their work with others and you can get ideas for your projects by subscribing to our Clownsletter.

Get Ready

In our world it means to prepare a center of your IoT system - the Hub.

In QUICK START GUIDE we will use your computer as a Hub.

Just follow these steps:

  1. In delivered box or suitcase find a Radio Dongle and plug it to any USB port of your notebook or PC.

  2. Download the latest BigClown Playground

  3. Run the BigClown Playground, go to the Device tab, choose the Radio Dongle serial port and click Connect

  4. Radio kits delivered together with your Radio Dongle are already programmed and paired, please check that out in the image below.

Build devices

By building devices we mean putting modules and enclosure together, optionally flashing a new firmware and pairing devices with a Radio Dongle.

QUICK START GUIDE recommends to follow this steps:

  1. Build delivered kits or build devices from modules (check the video guides how to do so). Do not put batteries to the battery modules yet and be careful how to connect Mini Battery Module from the right side.

  2. As mentioned, delivered kits are already programmed with a right firmware. If you would like to change it to another firmware in the Core Module, please follow this firmware flash chapter.

  3. As mentioned, kits delivered together with Radio Dongle are already paired and should be visible in Playground's Device tab. In case you need to pair new devices, please follow these radio pairing instructions.

  4. Switch to Playground's Messages tab and put batteries to your kit, you should see incoming messages. Every kit sends different messages. Here the Button kit sends temperature, voltage, event-count (everytime you press the button) and other messages.

  5. Put modules to the 3D-printed enclosure and fix it with O-rings.

Add function

Now it's time to give your system a logic and connect it with desired platforms.

In QUICK START GUIDE we will create a simple dashboard with a temperature gauge. Again, just follow these steps:

  1. Switch to the Messages, you should see incoming messages from the previous step. Copy the bold text (called topic) that ends with temperature to the clipboard. Make sure you copy just text and no space before or after the text. Your topic could be different based on your kit name. You can also copy any other topic that your module supports from the MQTT topics list.

  2. Switch to the Function tab and from the color blocks on the left side drag and drop mqtt block and gauge block to the flow in the middle of the screen. The color blocks are called nodes. You can use the filter nodes text box to find the right block. Connect the two created nodes together.

  3. Double click on the gauge node. Change Label, Units and Range to your needs. Then click Done.

  4. Double click on the mqtt node and paste the previously copied topic from the clipboard. Make sure there are not any spaces before and after the copied text. Then click Done and Deploy button. You have to click on the Deploy everytime you make changes in your flow.

  5. Go to Playground's Dashboard tab and you should see a gauge with the temperature of the selected device. The temperature can take a while to appear. You can breathe on the module or reconnect batteries for immediate update.
