IR Communication

February 7, 2013

This tutorial explains how common IR communications works, as well as shows you how to set up a simple IR transmitter and receiver.
  • Nice write-up! Although, I think it’s the manganese dioxide cathode in the tantalum cap that is the truly evil part (polymer tantalums aren’t as bad).

    Also, not only does over voltage affect the breakdown, mechanical stress like heating during reflow can create weakness in the dielectric contributing to a breakdown. Proofing the capacitor is sometimes suggested (by applying voltage and limiting current) and can be done to “heal” the cap after reflow, but who wants to do that.

  • ??? E=hv

  • Ah, I see where I goofed it. Thanks for the catch. Fixed.

  • Very good point, I definitely should have mentioned something about balancing series caps.

    Although, FWIW, in this configuration, the highest voltage the series caps will ever see is 5V (barring any failure). The peak surge voltage is also 3V per cap. What would a failure look like in this configuration?

  • After 3 years of thinking about it, I think I have arrived at an answer.

    Does this work in a vacuum?

    Yes. PV uses energy from photons (aka light). Light does not need air to impart energy (see photoelectric/photovoltaic effect).

  • Only if you make an attempt to debug as well. :) Send me an email with what you tried and we can work together on it. aaron@sparkfun.com

  • waiting

    I have no idea.

    Don’t give up too quick. You might want to review some of the forum posts and do some debug work to see if you can figure it out. The fix might just be a few lines of code. I’ll try to take a look at it if I get a chance early next week.

  • I would love to help you out and want you to succeed, but I as well have deadlines for other projects that probably take precedent over a problem like this (considering this is a bug with a beta version of the Arduino IDE and has nothing to do with the MPL BOB).

    I would suggest either waiting for the IDE to come out of beta, attempt to fix the issue yourself and submit your results to Arduino, or move to another platform. Bottom-line, don’t use beta programs for mission/time critical projects.

  • That would be the inductor, part# CDRH2D18/HPNP-4R7NC.

  • So it looks like this is a problem with the beta version of the Arduino IDE supporting the Due, not the breakout board. There is some talk in the Arduino forums about i2c not being fully implemented on the Due. I can successfully test the MPL breakout on other platforms, but the Due fails. Bottom-line, the Arduino software you are using for the Due is in beta, so you can’t assume everything will work.

    EDIT: There might be a way to get it working by modifying the sketch (although I am not sure exactly what the problem is). Also, since the sketch works with all of the other Arduino boards, I assume this bug for the Due will be fixed in Due time.

No public wish lists :(
