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.

Button

Servo

LCD

Photocell

Potentiometer

Relay

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
