A remote made for making presentations easier by enabling all the members to have access to change the slide and control the flow of the presentation in real time.

The primary functionality of this application is divided into two modules:

• A remote control that transfers the signal to the receiver
• The receiver receives the commands and executes them on the host computer

When you interact with the remote, a document is added to the database (firestore)

# Send info to receiver
def add_doc(self, action):
	self.db.collection("remote").document("current").collection("clicks").add({
		"action": action
	})

Which is then picked up by the receiver, which is always listening for these events. The receiver then simulates the necessary keystroke on the host system.

# Action was performed by the remote
def onSnapshot(snapshot, doc, time):
	send_input(doc[0].document.to_dict()["action"])

And this is all there is to it

You will have to setup a few things before you can get this working

• Setup python and have the dependencies installed
• Setup your firebase project and place the admin sdk credentials as credentials.json file in the same directory
• Optionally converting this application into a binary for easier sharing and usage

Checkout my blog for a full setup guide

If you want a ready-made executable make sure to checkout the releases but it will require the credentials.json file everywhere you run the executable hence I suggest you build an executable specifically for you which includes the credentials in the code. A full walkthrough is available on my blog

• Go to the previous slide
• Go to the next slide

• Start/Stop Presentation functionality
• A third dashboard module which can:
  • Create user accounts and bind them to the MAC address
  • Create user roles
  • Limit access to features as per the user / user role
