This project is based off of the Adafruit NextBus transit clock (found here: https://learn.adafruit.com/nextbus-transit-clock-for-raspberry-pi/overview). We have repurposed the hardware and code to show realtime slack updates and more!
-
You will need to buy and set up the following hardware list:
- Raspberry Pi 2 or Raspberry Pi 3
- We used a Raspberry pi 2 on a Raspbian distro
- Will need to have network connectivity (wired or wireless)
- Should be powered on its own power supply
- Will need an SSH server set up
- Adafruit Matrix-HAT
- We use this "HAT" to sit on top of the raspberry pi and interface with the LED Matrices seamlessly. This hardware makes life easy.
- The power supply below will connect to this to power the LEDs
- LED Matrix Panels (We used two 32x32 6mm pitch LED Matrix Panels for this project.
- 5V 10A Power Supply (This is going to be plugged into the Matrix-HAT. Should be enough power for up to 4 LED Matrices)
- Slack admin access
- Raspberry Pi 2 or Raspberry Pi 3
-
I used the nextbus transit tutorial to set up and test the Matrix Panels and hardware. Please follow the tutorial here: Adafruit NextBus Transit Clock Hardware Setup

Once you have the hardware set up and tested, we can move onto getting our software up and running.
- Clone this repo
- Create your slack bot on the slack admin panel and copy the API Token to your clipboard.
- Add the API token to
SLACK_TOKENin the slack.py file - Run
sudo python slack.pyon the Raspberry Pi - Add your bot to any channels you want it listening on, and watch the LED matrix panels display the activity!
