/PowerpointController

PowerPoint Remote using MIT app inventor and Arduino

Primary LanguageC++

Powerpoint Controller

The entire idea based on:
If you do not want to stand in front of the laptop during the presentation so you decdied to use a Powerpoint controller to switch between the slides.

The problem:

There is no such a device in your school or in your university :(

The solution:

Let make one

Project structure

Components & supplies :

  1. Arduino Uno
  2. HC-05 Board
  3. Jumper cables

Softwares & web application :

  1. MIT app inventor
  2. Arduino IDE
  3. PyCharm

Let develop the App

I used MIT app inventor, it is a web application integrated development environment originally provided by Google, and now maintained by the Massachusetts Institute of Technology.

You only need a Google accoount to develop the App

To show and to check if the connection is successful or not:

Sending Data if the connection is successful:

Let receive data from the App to the Arduino:

the circuit:

the code:


char datafromUser=0;
void setup(){
Serial.begin(9600);
}
void loop(){
if(Serial.available() > 0){
    datafromUser=Serial.read();
    Serial.println(datafromUser);
    }
}

Let process the received data in python

First of all, we need to install to python libraries

pip install pyserial

and then

pip install PyAutoGUI

the code:

import serial
import pyautogui
ser = serial.Serial('COM5',9600)
ser.flushInput()
while True:
        ser_data = ser.readline()
        data = chr(ser_data[0])
        print(data)
        if data == "R":
                pyautogui.press('right')
        if data == "L":
                pyautogui.press('left')

Happy Hack :)
