Control your mac keynote app with an arduino.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Things Needed :
Arduino (I'm using uno but any should do).
USB cable for the arduino.
IR receive diode.
Universal IR remote.
jumper cables for the IR decoder.
Step 2: Connect the IR Decoder to the Arduino
connect the IR decoder pins to the arduino as :
left -> pin 2
middle -> GND
right -> +5V
Step 3: Find a Nice Looking Enclosure (optional)
I used a cardboard box just to make the project good looking without the showing the arduino and the wires.
Step 4: Download the App
go to my website, head to apps page and download the keynote controller app.
this app lets you control your keynotes with the serial port , for example if the app received "forward" from the serial port it's connected to it will move to the next frame in the keynote
the app supports the following commands:
"start"-> starts the keynote presentation
"stop" -> stops the keynote presentation
"forward" -> moves to the next slide
"backward"-> moves to the previous slide
Step 5: Decode and Save the Remote Signals
use this code to receive the signals from your remote to assign commands to them later.
Step 6: Arduino Code
use the previously read commands in the switch of this program to send commands to the app.
Step 7: Connect the App to the Arduino
open the app and choose the serial port which the arduino is connected to then set the baud rate to 9600 (for the previous sketch) then click connect.
