Control low power 3v LED fairy lights / Christmas tree lights from a Raspberry Pi
Allows patten to be changed from a hardware button, and now also a web interface.
This code requires 3 low power LED fairly light strings/strips that run at around 3v. Or to simply test or develop with this code 3 LEDs would work.
The hardware list and circuit diagrams are both below
v2.0.1
- Control multiple light strings of fairy light connected to the GPIO pins.
- Threading of LED control.
- Patterns/effect - All on, Rotate, Twinkle (slow/medium/fast), Sparkle (slow/mediuam/fast), All off.
- Software PWM to allow fading in and out of light.
- Hardware button for on off / cycle through patterns
- Logging - rotating log to /var/logs/pi-fairy-light-control/pi-f-l-control.log
- Web interface to control light patterns (http://hostname:5000/)
- none
- More differnt patterns and effects
- Smart Home Integration
- Apple HomeKit intergration (can be controled on local network, prefered)
- Alexa Skill for ccontrol from Echo devices (needs an endpoint viable in the internet, would want to run in IoT LAN or DMZ)
- Philips Hue with a Zigby Hat/dongle. (Should then intergrate to Alexa/Apple/Google etc)
- Run as Daemon
- Install scripts
- BPM detaction options
- Photorisistor to control light strings at differnt light levels.
wget https://github.com/fr3qu3ncy/pi-fairy-light-control/archive/v2.0.1.tar.gz
tar -zxvf v2.0.1.tar.gz
rm v2.0.1.tar.gz
sudo apt-get update
sudo apt-get -y install python3-rpi.gpio
sudo apt-get -y install python-pip
python3 -m pip install --upgrade pip
sudo pip3 install flask
cd pi-fairy-light-control-2.0.1/
python3 pi-f-l-control.py
You can run under python2.7 if you wish.
When you start the code python3 pi-f-l-control.py the LED lights will all be off, or lit in their last static state.
Pressing the button will cycle through the available patterns in the following order:
- All On
- Rotate
- Twinkle Fast
- Twinkle Medium
- Twinkle Slow
- Sparkle Fast
- Sparkle Medium
- Sparkle Slow
- All Off
New in v2.0.0 and above there is a web interface to control the pattern running, and display the curently running pattern.
In a web browser, go to http://hostname:5000/ replacing hostname with the hostname of your Raspberry Pi
To add the web interface as a web app to an iPhone or other iOS device, click the share button at the bottom, and select Add to Home Screen
- LED - Fairy Lights x3 - Low voltage 3.3v fairly lights.
- I used these battery powered lights from Amazon UK. I cut of the battery pack, and crimped on Dupoint conenctors.
- S - Push button
- Any push button switch
- R 1-3 - 330 Ohms resistors x3
- R 4 - 1K Ohm resister x1 - Ptotect GPIO pin incase accidently set to output.
- R 5 - 10K Ohms resistor x1 - Pull up the state of the GPIO pin.
- Raspberry Pi
- Breadboard
- Dupoint connection cables (various)
