A small presentation regarding how the Blynk project works, made for an Individual Project for the Pervasive Systems exam at the Univerisity of Rome "La Sapienza"

1. Blynk
Davide Meacci, La Sapienza
Pervasive Systems Individual Project:

2. Davide Meacci, La Sapienza
Blynk is a Platform with iOS and
Android apps to control Arduino,
Raspberry Pi and the likes over the
Internet.
What is Blynk?

3. It's a digital dashboard
where you can build a
graphic interface for
your project by simply
dragging and dropping
widgets.

4. But most importantly...
Davide Meacci, La Sapienza
It is really simple!
To set up all the required environment
(Server, Client and Board)
5 minutes are more than enough.

5. Now, a lil’ bit of

12. Main Operations
Davide Meacci, La Sapienza
- Interact with Pins (Digital and
Analog)
- Send and Receive data from
Hardware
How?
Blynk allows us to:

13. … with Widgets!

- Data Mapping
- Split/Merge

15. Controllers
Davide Meacci, La Sapienza
- Button
- Slider
- Timer
- Joystick

16. Displays
Davide Meacci, La Sapienza
- Display
- LED
- Graph
- LCD
- Gauge

17. Notifications and Other
Davide Meacci, La Sapienza

- Email
- Bridge

18. Is it possible to run a
local server?
Davide Meacci, La Sapienza
The answer, of course, is YES.
1. download the Web-server from the Website
2. start the server locally
3. set up Router to enable port-forwarding
4. Set the server from the Blynk App
