LEDctrl backend

Server application for LEDctrl app.

This Node.js project was designed to run on a Raspberry Pi alongside RPI-WS2812-Server to control a WS2812 led strip. In the repository is also a configuration for managing both applications with supervisor.

Things needed

• WS2812 led strip
• Raspberry Pi
• Power supply for the led strip (optional, depends on the amount of leds you want to control)

Setup

• Connect your led strip to the Raspberry Pi. See this article for more information
  Make sure the led strip is connected to GPIO pin 18
• Install RPI-WS2812-Server on your Pi in the home directory ~/rpi-ws2812-server
  See Installation
• Clone this repository into ~/LEDctrl-backend
• cd into the project folder
• Run npm install and npm run build
• Install supervisor with apt-get install supervisor
• Copy the config file supervisor/ledctrl.conf to /etc/supervisor/conf.d/
• Run supervisorctl reread and supervisorctl update
• supervisorctl status should display both applications as RUNNING
• Open the settings of the app on your phone and enter the settings
• Enter the ip or hostname of your Raspberry Pi in the corresponding field
• Congratulations! You should now be able to control the leds via the app
