This tutorial covers the basics required to work with "Wio Node" and its sensors (Groves). With help of this tutorial one should easily setup his Wio Node with Digital RGB LED Strip and make it glow without a need to code.
The very first step is to install “Wio” application from SeeedStudio.
While I was preparing this document, I made use of an Android mobile device. Hence, I chose to install the application from Google Play Store. Please take necessary help from the below screenshots and proceed.
In search field enter Wio / Wio Link to search for application.
Select “Wio” from “SeeedStudio.com”. The very first one on list.
Select “Install” and proceed to the next steps.
Accept to allow application access.
Please allow some time for mobile device to install the application.
With this, we complete Step 1 - Installation of Wio App on Android Smart Phone.
On completion of Wio Application Installation, access the application by selecting “OPEN”. Provide user credentials and logon to the application. End user has options to make use of Google+ (or) Facebook to login.
Select “ADD YOUR FIRST DEVICE” and proceed.
At this stage, connect either Wio Link (or) Wio Node physically to a PC/Laptop/Mobile Battery charger. For this tutorial, I chose to go ahead and connect Wio Node
As I connected “Wio Node” to my Laptop, I selected the same icon from the listed of devices.
As suggested in the screen hold down the “FUNC” (function) button. Please take necessary help from the below image to identify “FUNC” button. I suggest users to have a magnifying glass for better readability of text on Wio Node.
Allow to share the location of device.
Connect to your choice of Wireless router from list of routers that get displayed in this screen.
Provide password if the router is configured with one for Internet access.
Select the listed Wio Device. “Wio_095897” in this case.
The application interface provides a chance to name the Wio Device. I chose to name it “AmruthWN01”
The device successfully gets included showing it to be available “ONLINE”.
On selection of listed device, other connecting devices (Input/Output/GPIO/Analog) are listed on the top ribbon.
To continue with the experiment, I chose to connect “WS2812 LED Strip 60”.
The device (WS2812 LED Strip 60) has to be selected and dragged on to the space provided. Select “Updated Firmware” to continue.
On successful completion of firmware update, select “View API” from “Menu”. At this stage, do not forget to connect the LED strip to the correct port on Wio Node.
Navigate down the API screen and check its functionality. I chose to check the functionality of LED strip glow by providing parameters “Total LED Count: 20” and “RGB Hexadecimal String: AA55CC” in “Test Request” section. Select “POST” after providing the parameters and observe the LED strip glow.
With this, we complete this very simple project.
