Presentation Driver

Abstract

This is a remote command use for change slide in Presentations. Use arduino for send a command in serial-mode to a receiver program. The receiver program, emulate arrow key press and change slide.

Mission

This project is created for IoT meetup Milano

PoT - Tocca con mano quello che scrivi

It's a basic example to use arduino with serial

Electrical Scheme

In docs there is an Electrical scheme for build a device Use Fritzing for open and look how connect all components

Components

• Arduino uno
• 1 Led Diode Red
• 1 Led Diode Blue
• 2 10K Resistor
• 1 220Ohm Resistor
• 1 100Ohm Resistor
• 2 Switch

Usage

We can use three different receiver

• Busy waiting in Python
• Async in Python
• Async in Node.js

Installation

Python

Create virtualenv and install packages with command

pip install -r Requirements_Mac.txt

Node

Move in Node.js folder and write this command in shell

npm i

Arduino

• Connect Arduino via USB and load PresentationDriver.ino
• Restart Arduino

Dependences

Python

• Use Python 3.6 for asyncio
• PyAutoGui
• PySeral

Node.js

• Robojs

• SerialPort ##Use Connect Arduino on usb ####Python Launch:

  python presentation_driver.py --list In this way get all serial port in monitor Copy name of arduino port and launch

  python presentation_driver.py -p portName

For asyncio

python presentation_driver_async.py -p portName

Node.js

Launch:

node app.js --list

In this way get all serial port in monitor Copy name of arduino port and launch

node app.js -p portName
