Using a for example a WS2812 5050 RGB LED this Discord bot shows how many of your friends are logged in to your Discord server. Excludes the channel AFK when counting users.

Tested and confirmed working with discord.py version 1.1.1.

• stdout (for testing)
• WS281x
• Blinkstick

Solder the LED strip to pin 18, +5V and GND respectively.

• Shows a red LED up top when the bot is online but noone is logged in.
• Flashes leds when a new user joins.
• Shows up to the maximum number of leds of the attached led strip.

Create two files in the boot partition, one empty called ssh and one called wpa_supplicant.conf with the following contents (edit to fit your network):

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="your_real_wifi_ssid"
    scan_ssid=1
    psk="your_real_password"
    key_mgmt=WPA-PSK
}

Clone the repo, obviously.

Choose the appropriate script depending on your output interface.

sudo chmod +x provision_<CHOOSE_VARIANT>.sh
sudo ./provision_<CHOOSE_VARIANT>.sh

Set up a Discord bot (Google for instructions if you don't know how). Add your Discord bot token to a text file called apikey.txt in the repo.

Set your preferred output module at line 13 in usercounter.py.

python3 usercounter.py &

or add an @reboot line to crontab (using the provided add_cronjob.sh):

@reboot sudo /usr/bin/python3 /home/pi/ledusercount/usercounter.py > /home/pi/cronjoblog 2>&1
