I’m also on the EEVBlog forum as MrAureliusR. Just discovered SparkFun – what a handy website! The breakout boards in particular are extremely handy. Will be ordering many things soon!

  • Remember that the 5V line going to the strip is not going through the Arduino, it’s simply drawing it from the same source as the Arduino (either USB or the power jack) so the individual pin limits have nothing to do with powering the LEDs themselves.

  • No, the LEDs on here are WS2812, therefore you don’t need to drive them with PWM – they take care of all that internally. You simply send serial data down the string and they change colour and brightness automatically.

  • Check out what I got this round! https://youtu.be/jScJv2zzrxQ

  • GRRR I freaking missed it AGAIN… man, this is so bullshit, people waiting until the exact second it’s posted and then hitting F5 till they get it. These should be given away as prizes for actually building something cool, instead of whoever happens to be on their computer in the what, 2 minutes they lasted this time??? I wish I could swear here…

  • I just got a notification that this was available, and the box isn’t even showing up on the right?? WTF?

  • You do realize there’s a schematic link right above?

  • Ugh, good point. The example pics make the assembly look horrid. Any comments, SFE?

  • So what’s going on? After I replied to the email requesting my Twitter handle, I completed five challenges, tweeted them all to @Sparkfun before the deadline, but haven’t heard anything yet. Still tallying?

  • For those curious, I’ve found the best way to get good, repeatable results with this sensor is to set the transistor up as an open collector, with a 10k pull-up. (This means tie the emitter to ground, and measure the output at the collector). Then have a 1k high-side resistor on the IR led, and the difference between white and black reflectors is immense. White brings the signal almost to ground when it’s close, and black hardly budges at all. If you have any questions, feel free to reply.

  • What happened to the ½" ones? In my experience 3/8" is too small and 1" too big in the majority of situations. ½" was perfect!

If I had just a little bit more moolah, my lab would be THIS MUC…
