Inspiration

We wanted to to use something useful for communication. We had a bunch of Raspberry Pis, LEDs, and wires, and we wanted to make the Pis communicate somehow.

What it does

We have two Raspberry Pis, wired together on one breadboard using GPIO pins. One Pi runs a Python script that takes an input String and converts it into Morse code, and then outputs the Morse code with a blinking LED light. The other Raspberry Pi is wired to a photoresistor that detects when the LED blinks on and off. It then converts the detected changes back into English.

How I built it

We wired up the Pis to a breadboard, installed Raspbian, and wrote the Python.

Challenges I ran into

The algorithm behind converting the detected LED blinks into Morse into English was especially tedious.

Accomplishments that I'm proud of

We wired two Pis to a breadboard and didn't blow up any LEDs!

What I learned

Python is a lot like Java.

What's next for TelegramPi

We go further into the history of the communication industry, creating the PiNy Express.
