RasPi-Telegram

Proof of concept bot written by Patrick Szalewicz from Hochschule Bremen for his presentation. This bot uses the Telegram API as well as a Raspberry Pi Zero W to illustrate how IOT devices are working.

Features

LED blinking! What time is it? Roll the dice!

Special feature: Blink LED at startup if network is present or not.

In my example I used four LEDs wired as following:

• Red = GPIO 21
• Yellow = GPIO 5
• Green = GPIO 10
• White = GPIO 27

Please change the values in the scripts if you use other GPIO pins.

Installation

This bot requires the following programs:

• python
• telepot
• git
• gpio (should be already installed on Raspbian)
• nano (or any other text editor, like vim)

every command should be issued using the 'sudo' command. It's easier to do the following once.

$ sudo su

Install the dependencies before you install the bot:

$ apt install python git nano
$ pip install telepot

installing the bot:

$ git clone https://github.com/fachinformatiker/RasPi-Telegram
$ cd RasPi-Telegram
$ cp opt/* /opt/
$ cd /opt
$ chmod +x *

insert your token inside the bot file: bot = telepot.Bot('INSERT YOUR BOT TOKEN HERE!')

$ nano bot.py

autorun at startup:

$ crontab -e

and insert the two lines from the crontab.txt file.
