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.
  • I'd love to hear more about how you did that. I'd like to update a few boards as well.

  • We are looking at different options, but haven't settled on anything yet, but we are definitely looking into it.

  • Thank you for your feedback, we are constantly working to get better shipping prices and improve customer experience. As for the 1-5 vs the 3-11, those are 2 different methods as defined by FedEx, we've just chosen to not list them by name but by time frame which makes more sense to people, but I understand how it can be confusing. I will pass along your concerns and thanks again for your feedback.

  • To our knowledge no one has tried it (although if they had they might not have told us). We just wanted to be extra careful.

  • It's been on my radar to write. I'll look into it.

  • It is just a bunch of PTH holes that are not connected to anything. You will have to wire them to the Arduino yourself (probably running a wire from the proto area to the extra row of shield headers). Check out the hookup guide for more information as there is a whole section that goes over the proto area.

  • Based on the outline and the polarity markings on the bottom of the board, this header is designed to be used from the bottom of the board.

  • One of the main reasons was microcontrollers may or may not have pullups and we wanted to make sure our I2C boards will plug and play. Whether or not your microcontroller has pullups or not you should be able to plug in the board and just get started, you only tend to start running into problems when you have quite a few (in which case the new trace solder jumpers are the easiest option for change). In other words what Englandsaurus said as well as wanting these to be as easy as possible to start with.

  • Hmm, I have drill sizes and wire gauge, but not that, I'll definitely consider that for a 'respin'.

  • I did consider doing 10<sup>-6</sup> instead of 10^6. I agree it is generally easier to use I didn't want to make the exponent too small on the ruler since that is the number you actually want to see. I actually don't think I've ever heard of ELI the ICE man, not sure how I missed it. I'll definitely consider the others if we do a revision though.
