Introduction: Taurus Platform and DragonBoard - Digital Actuator
Taurus is an open platform designed for makers and students to control your things by a dashboard that offered the ability to control most types of internet devices from things. The control panel can be composed of digital actuators that allow 2 states actions and can be used to turn on or off a certain device and have a 0 or 1 response; Analog actuators that can assume infinite values and be used to modify the operation of a device, such as the temperature of an air conditioner; And finally, sensors that store data sent by meters of various magnitudes in order to monitor the conditions of the environment in which the device is.
In this tutorial you will se how to connect Qualcomm DragonBoard to Taurus IoT Platform. We will control a LED connected to the board by a digital actuator component in Taurus.
Step 1: Creating Account in Taurus
- Open www.taurussystem.com
- Click at Login button, located at upper right of the screen
- Sign up
- Complete the fields with your name, e-mail and password. Dont forget to save the serial displayed, it is your API key for Taurus project.
Ok, now you have an account and can login into the platform!
Step 2: Creating Components in Taurus
After creating acount here is your dashboard,
Taurus has some Rest API's that create, update and consome data from the platform:
This API creates components in your dashboards, where:
xx = 10 for digital actuator
xx = 20 for sensor
xx = 30 for analog actuator
0 = initial value
SERIAL = API key got in account registration
for examples, create a digital actuator:
Step 3: Get Data From Digital Actuator
API for get data of a digital actuator:
yy : digital actuador id (01~99)
SERIAL: API key got in account registration
where "valor" property saves the state of the actuator.
You can see more about the Taurus's API in : Embarcados - Taurus, Brazilian IoT Platform
Step 4: Python Code in DragonBoard
Ok, lets see how to get the data from Taurus Platform and show it in a LED connected at the board.
First, download files:
- $ cd Dragonboard/Taurus
To configure board GPIO see: https://www.instructables.com/id/Qualcomm-DragonBoard-Configure-GPIO/
- $ sudo pip install requests
- $ sudo python main.py
Connect a LED to pin 23 of the board and go to the platform to turnon/off the LED.
Thank you, best regards.
We have a be nice policy.
