IoT Control Panel

Functionality:

IoT control panel that use firebase as the database the control led and motion sensor from beaglebone. The output of the motion sensor will be Classified into long(>=3seconds) and short(<3 seconds) motion. The program will then translate long and short (Dash and dit) into it's corresponding alphabet based on morse code.

Version Log:

v1 Update log:

• Basic functionality on translating morse code in to english alphabet from A-Z.
• Basic interface for the client
• User can enter data through motion sensor
• Motion detected will be printed in the server console
• Server can determine incoming signal is a long or short motion
• The long or short signal will also be printed on the client side
• Output message based on the combination of input received by the motion sensor.
• Start new morse code after 3 seconds of no motion
• Start a new word after 7 seconds of no motion

v2 Update log:

• Added numeric morse code
• Added punctuation morse code
• Allowed client side to start and end the transmission
• Added SK prosign to end the transmission

File Overview:

File	Function
/app.js/	For the server to run motion sensor and led
/firebaseWebApi.js	For client to send command and receive result.

Hardware structure

• Microcontroller : BeagleBone Black with Debian V8.7
• Power supply: Micro USB connected to computer
• Sensors: Motion sensor
• Cables: 5 male to female jumper wires
• Output : led light

Libraries

• Node.js(pre-installed)
• Bonescript(pre-installed)

• Firebase-tools

Pin Set UP

LED light

• Connect the negative pin to the DGND (P8 02 )
• Connect the positive pin to the GPIO (P8 08)

Motion Sensor

• Connect the out pin to GPIO (P8 07)
• Connect ground pin to DGND (P8 01)
• Connect VCC pin to sys_5 (P9 08)

Limitation:

• You need a working internet connection for it to work

Known bugs:

• Depending on internet connection there might be a delay in transmitting the morse code

How to set up

Set up the beaglebone. This includes installing drivers for respective OS.

Once connected. Ssh to the beaglebone by running

$	ssh [email protected]

Clone this repository into a directory in beaglebone black

Install all the dependencies by running this code on terminal

$	npm install

Run server.js. This will start the motion sensor

$   node app.js

Run firebase server. It will create a server listening to port 3001

$   firebase serve -o 192.168.7.2 -p 5000

Navigate to your server in your browser
