[Dynamic Living-Room Lights] The Lights Teaser Video

ipv1

List of previous posts

 

The Teaser

The project documentation is taking forever and I will release it much more systematically. For now, here is a small video of one of the parts which is the audio controlled LED lights. I am using the ARDUINO RGB LED SHIELD, XMC1202ARDUINO RGB LED SHIELD, XMC1202 and an Arduino. I am using an analog filter and the details will be released in an upcoming post.

 

 

Cheers,

    Hi Inderpreet!

     

    Lets do a short non-recorded one next time maybe? webex if possible? But I'm not sure when to suggest in terms of time : ( During weekdays January-Feb is the busiest time of the year for me : (

    We missed both Shabaz sir and you at the hangout last night

    Yeah sorry I missed the time change, and I'm watching it now.

     

    Anyway another time ...

    it is probably the fade time or walk times, this is a setting that controls how long it takes to go from one colour to the other or one brilliance to another

     

    This is my initialization steps

    RGBLEDS.I2CWRITE2BYTES (ADDRESS, OFFTIME_RED, 0x38); // Set off-time of red channel to 0x38
      RGBLEDS.I2CWRITE2BYTES (ADDRESS, OFFTIME_GREEN, 0x39); // Set off-time of green channel to 0x39
      RGBLEDS.I2CWRITE2BYTES (ADDRESS, OFFTIME_BLUE, 0x38); // Set off-time of blue channel to 0x38
      RGBLEDS.I2CWRITE6BYTES (ADDRESS, CURRENT_RGB, 0x80, 0x80, 0x80); // Set current of red channel to 0x80 = 780mA
      RGBLEDS.I2CWRITE2BYTES (ADDRESS, FADERATE, 0x0005); // Fade Rate between intensities --> 0.0s
      RGBLEDS.I2CWRITE2BYTES (ADDRESS, WALKTIME, 0x0010); // walk time between colors = 0s
      RGBLEDS.I2CWRITE6BYTES (ADDRESS, INTENSITY_RGB, 0x0555, 0x0555, 0x0555); // low level White Light
      RGBLEDS.I2CWRITE2BYTES (ADDRESS, DIMMINGLEVEL, 0x0FFF); // Maximum dimming level means intensity settings are directly used

     

    if you set the value of the two bold lines to zero then it should change instantly

    Thanks mark sir,

     

    The circuit is appreciated.

     

    In this instance the target is to use the infineon shield because the same lighting is supposed to be controllered over Ethernet as well hence i had to do the whole Arduino thing.

     

    We missed both Shabaz sir and you at the hangout last night. I will try and schedule one at a more comfortable time the next.

     

    Cheers,

    Hi Shabaz sir,

    I think the problem is something with the led strip itself. The inductor needs to release the stored energy and in my vase there is a series resistor which increases the field collapse time. I might try and increase the i2c speed so that the response is quicker though.

     

    Thanks
