CameraLED

Pure python library to control Camera LED for RaspberryPi 3
It is compatible with both python2 and python3

Background

I bought an ArduCAM with motorized IR Cut Filter.
The IR Cur filter is connected to the camera LED, so by controlling the LED you can control the IR filter.
They provide a precompiled library to control the LED but it wasn't working for me.
So i decided to write my own pure python library to control the camera LED (and IR filter) on Raspberry 3.
My library does exactly what their precompiled library does.

Prerequisites

You have to disable the automatic management of camera led in /boot/config.txt.

$ sudo echo "disable_camera_led=1" >> /boot/config.txt
$ sudo reboot

Installation

$ wget https://raw.githubusercontent.com/BigNerd95/CameraLED/master/CameraLED.py 
$ chmod 755 CameraLED.py

Usage

You need to be root (or at least be able to use sudo).

Standalone

You can use my library as a standalone command:

$ sudo ./CameraLED.py 
Usage: ./CameraLED.py (state|toggle|on|off)

$ sudo ./CameraLED.py state
State: 0

$ sudo ./CameraLED.py toggle
State: 1

$ sudo ./CameraLED.py toggle
State: 0

$ sudo ./CameraLED.py on    
State: 1

$ sudo ./CameraLED.py off
State: 0

Python library

You can use my library in your Camera projects

from CameraLED import CameraLED
led = CameraLED() # CameraLED(134)
led.on()
led.off()
led.toggle()
led.state()

Photos

LED OFF = NO IR filter = Night vision

LED ON = IR filter = Daily vision
