Description: BlinkM is a “Smart LED”, a networkable and programmable full-color RGB LED for hobbyists, industrial designers, prototypers, and experimenters. It is designed to allow the easy addition of dynamic indicators, displays, and lighting to existing or new projects. If you’ve used up all your microcontroller PWM channels controlling RGB LEDs and still want more, BlinkM is for you. BlinkM uses a high quality, high power RGB LED and a small AVR microcontroller to allow a user to digitally control an RGB LED over a simple I2C interface. Multiple BlinkMs can be stranded together on an I2C bus allowing for some amazing light displays.

BlinkMs are also programmable! With ThingMs sequencer software, you can create a mix of colors with different time slices, upload that sequence to the Blink, and then let it rip.

Features:

  • 8000mcd 140º full-color RGB LED with 24-bit color control
  • Specify colors by 24-bit RGB or HSB
  • Fade between colors with variable timing and fade speeds
  • Randomized color selection, with ranges and based on previous color
  • 18 built-in light scripts (sequences)
  • Create and save light scripts of up to 49 commands long
  • Stand-alone operation: No microcontroller needed for light script playback
  • Can plug directly into Arduino, no wiring or other components needed!
  • Two-wire (aka “I2C”) interface
  • Up to 127 BlinkMs on a single two-wire network
  • Responds to “general call” broadcast for simultaneous commanding
  • Reconfigurable network address
  • Firmware upgradable
  • 5-volt standard TTL inputs
  • Low power consumption

  • The software is junk. not in synch, cant upload. Stack errors galore. Mod the code to get it to work, and it wont communicate at all.
    The soldered joints are full of dried flux, they didnt take the time to even clean the boards. Two cold joints on a BlinkM and 4 on the BlinkM Blaster
    Returning these pieces of crap. YES I even followed their quickstart guide. ALL HYPE
    big thumbs down.

  • Lectric, I am sorry you experienced problems with our products. Please send a note to blinkm@thingm.com and we will replace your BlinkM and MaxM Blaster.
    For the software errors, please see our forum on Get Satisfaction:
    http://www.getsatisfaction.com/thingm/products/thingm_blinkm
    If the problems you had are not addressed there, please post them there or email us at blinkm@thingm.com and we will look into it immediately.

  • Please ignore my previous comment - was getting a bit frustrated after three hours of looking for a solution - have now worked out that both of the files for the communicator were not in the same folder. Hope this helps any others Noobs out there. David.

    • Glad to hear you figured it out! Sorry for the frustration on that. If you do have any other questions moving forward, you can always email techsupport@ and they’ll be able to help you out quickly.

  • Hi One & All, can anyone tell me what to do with these. I have just received two and downloaded the latest arduino software and the BlinkM sequencer but am getting lots of compiling errors - as below. Do I need a different library of files for WIRE or something. I can only find vague references from a year ago or so to similar issues, and would have thought these would connect easily??? Thanks David.

  • I made a RGB LED dog harness with these: http://www.youtube.com/watch?v=6aXk2gZiHwo

  • Just received mine. The site has been down though. I can’t get sample code or a datasheet.

  • Can these be programmed with a ftdi cable? I’d like to get one cable that can do both Arduino and Blinkm programming. If so which one would be best?
    Thanks in Advance

  • What frequency does the PWM flash at? Will I see “horizontal blinds” in captured images using a simple CCD at partial brightness?

    • BlinkM’s PWM rate is 120Hz. You will probably see artifacts unless you can control your shutter speed.

  • Is the source code for the BlinkM available, or is it closed source?

  • What is the name of the package type of the LED? Do we have a datasheet on it?

    • It’s a piranha RGB LED. It’s not from a manufacturer that publishes data sheets, but if you search Ebay for “piranha RGB LED” you will find many like it, and the auctions have a lot of the same information you’d find in a formal data sheet.

  • I will say that you need to power up the BlinkM and the device your using at the same time or it will not talk at all. I could not figure this out at all but a forum post help me get on the right track. hint Only thing I can say is a beef is to be very careful to watch how you power off your BlinkM/device or you will brick it. I think I did this by mistake to one of them since the Mini does not have an 5v out. Read the PDF fully before hooking it up. Software worked great on my Pro Mini and board does not have flux issues or cold joints like said before.
    Talking with my brother about the Max he said he does not see any issues with his device other than it’s real freak'n bright. :)

  • A while a go I made this simple lamp using a blinkM module. Easy and cool.
