How to Use a Breadboard

May 14, 2013

Welcome to the wonderful world of breadboards. Here we will learn what a breadboard is and how to use one to build your very first circuit.
  • Can you please clarify which image you’re referencing? Thanks.

  • You can cover the Touch Pot with numerous plates and enclosures. Just be sure to re-calibrate afterwards to get the best results.

  • Sorry to hear about your 9V incident. The modules shipping on this are still the RN52-I/RM I believe.

  • lol, I suppose you could make it smaller if you wanted. The purpose of the milled-out L shapes is to help with parasitic heat from a system. If you had this sensor soldered to a board that ran warmer than the environment you’re trying to measure, it will give you inaccurate data. Not having a copper pour and reducing the surface area of the PCB helps to keep the readings from the sensor closer to accurate.

  • Hi, we’ve recently been adding the dimensions in our Eagle design files. This revision went through before that became the standard, however, you can open any of our board files in Eagle and use the measure tool to get any of the dimensions you need. I took a screen shot of the WAV Trigger after I added the dimensions for your convenience. Thanks. The units are in inches.

  • The Streaming Tunes section of the Hookup Guide contains that information.

  • Hi, sorry for the inconvenience. I’ve reordered the pages so that the demo sketch comes first, then the hello world/learning how to program page. If you downloaded the SparkFun MicroView Library for Arduino, then you should have the sketch in the examples folder (titled MicroViewDemo). I added a note in the tutorial about how to get this sketch back on the MicroView. You can also get the sketch directly from here.

  • Hi, I just tried the Phant example and it is working for me. Make sure your field labels match the labels used in the PostToPhant function exactly. Use phant.add(<field>, <value>) to add data to each field. Phant requires you to update each and every field before posting.

    Also, make sure you have replaced the private and public keys near the top of the sketch with your keys.

  • The Photon definitely runs on the warm side and causes parasitic heat throughout the PCB. We tried to eliminate as much of this as possible by routing out around the sensors. However, the readings still tend to be higher than actual, especially in an enclosure. You can compensate for the extra heat in the code.

  • The latest Photon Firmware has lots of fixes in it. You can find it here, along with instructions on how to push the update yourself. Or the Particle will be pushing out the new firmware in an auto update in the very near future.
