Information on using a Raspberry Pi as a Beeminder traffic light

• Pi Traffic Light for the Raspberry Pi
• Raspberry Pi 4 Model B/1GB
• Power supply
• Mini SD card to install Raspbian OS on
• For setup: monitor, keyboard, mouse
• Monitor adapter, if needed, such as this VGA one

• Install Raspbian on mini SD card
• Log into device using a monitor and keyboard
• Enable SSH in the Raspbian system preferences (source)
• Open Terminal
• Type ifconfig and find IP address of device on your network (source)
• On a different computer on the network, enter ssh pi@[your pi's IP] and provide password (default is raspberry) (source)
• Install Mu (may already be installed): sudo apt-get install mu-editor

• Set Git username: git config --global user.name "John Doe"
• Set Git email: git config --global user.email [email protected]
• Check your changes: git config --list

Source

• SSH into Pi
• sudo raspi-config
• Navigate to boot options, and set to "Console Autologin - Text console, automatically logged in as 'pi' user"
• Hit right arrow key until 'Finish' is highlighted, and press enter, opting to reboot the Pi when asked
• Reconnect via SSH once Pi has rebooted
• Install remote desktop server on Pi via SSH: sudo apt-get install xrdp
• Open (or install as needed) Microsoft Remote Desktop
• Configure new connection, using Pi's IP as computer name, and pi as username

Mount the traffic light component on GPIO pins 9, 10, and 11. If you're using the Pi 4 model B (pin diagram), it should look like this, with 7 pins to the left of the lights:

• SSH into Pi
• cd to desired location
• git clone https://github.com/narthur/beeminder-traffic-light.git
• cd into beeminder-traffic-light directory
• python3 -m pip install --user -r requirements.txt
• cp config-example.yaml config.yaml
• Edit config.yaml with your username and auth token
• python3 main.py

Your Pi's IP may change periodically unless you assign a static IP to it.

• Boot the Pi using a keyboard and monitor connected directly to it.
• Open terminal.
• Type ifconfig and find IP address of device on your network (source)

Run these commands on the pi, either directly or via an SSH connection.
