thing-it-device-microcontroller
[thing-it-node] Device Plugin for Microcontrollers (Arduino Uno and others) as well as GPIO access for Single-board Computers like Raspberry Pi or C.H.I.P.
This allows you to
- control the Microcontroller configuration over the Internet,
- define complex services, event processing, storyboards and Jobs combining the Microcontroller and its connected Devices, Actors and Sensors with other Devices, Sensors and Actors.
by means of thing-it-node and thing-it.com.
Installation
After you have
- set up your [thing-it] Node Box and
- configured or copied a [thing-it] Mesh with a TI SensorTag,
connect your microcontroller to your [thing-it] Node Box via a USB cable.
User Interface
The appearance of the UI of the Microcontroller Plugin on the [thing-it] Mobile Client depends on the configured Actors and Sensors
Actors
LED
RGB LED
Addressable LED (WS2812B)
The Pixel Actor only works with Arduino as Microcontroller and requires a custom version of the Arduino Firmata. Installation instructions can be found here.

Sensors
Light Sensor
Note: Light sensor uses i2c interface. For Microcontroller Typ: Raspberry PI this must be activated first via sudo raspi-config -> interfaces
Connection:
| Raspberry Pi pin (function) | TSL2564/BH1750 |
|---|---|
| 6/9/14/20/25/30/34 (GND) | GND |
| 1/17 (3.3V) | VCC |
| 5 (SCL) | SCL |
| 3 (SDA) | SDA |
Air Quality Sensor
Note: AirQuality sensor uses i2c interface. For Microcontroller Typ: Raspberry PI this must be activated first via sudo raspi-config -> interfaces
Connection:
| Raspberry Pi pin (function) | AirQuality |
|---|---|
| 6/9/14/20/25/30/34 (GND) | GND |
| 1/17 (3.3V) | VCC |
| 5 (SCL) | SCL |
| 3 (SDA) | SDA |
Once I2C is enabled, we need to slow the speed way down due to constraints of this particular sensor.
via
sudo nano /boot/config.txt
add this line to the file
dtparam=i2c_baudrate=10000
safe and reboot
