We all know that women are not only a minority in technical fields, but are often not encouraged to go into such fields. Here are a few ways to encourage and support the girls/women in our lives who are interested in technical fields.

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.
  • Nope, check out our FCC tutorial on how our stuff fits in with FCC guidelines. The short answer is as prototyping hardware it is not required to be certified. While most boards like this are built using the manufacture’s suggested circuit and should have no problems passing certification for a final product we do not go through the process to get our boards certified.

  • Check out the hookup guide, but it looks like you do not have to change resistors. Right now all of the jumpers have the middle pad connected to VDD and the other pads connected through a resistor making this effectively a pullup resistor circuit. In theory you can just pull them down, but you may want to cut the traces first. I’m guessing you just need to change the address of one of them. If you still have questions feel free to email our techsupport department and they should be able to walk you through it.

  • That is correct. All Pi boards have a microUSB port for power including the Zero. The Zero also has a OTG port to connect your peripherals. We’ll see about getting that updated.

  • We’ve had broken molds, fixed molds, suppliers machines have gone down, they’ve found more problems with the molds… We’ve had quite a few tentative dates and are still working to get these it. Right now we are still looking at tentatively March, but until we have them in the building we’re not promising anything.

  • The production for the mpr121 was indeed transferred. Doing so also increased the cost to the point where this board really wasn’t feasible to produce which is why we’ve retired it. I’d check out some of the other capacitive touch options available, but I don’t foresee anyone having breakouts based on this available for long.

  • We have no plans to sell the module alone, but we don’t do any programming of the module.

  • You will need to remove the blob of solder currently on the jumper (I usually double check with a multimeter or something to make sure it is fully disconnected). Then add a similar blob of solder connecting the middle pad to the 5V side. Basically the middle pad is connected to the VCC output on the board and the blob of solder is connecting that pad to either 3.3V or 5V.

  • That depends on what part of the Uno needs to be compatible. The Arduino Pro and Pro Mini use a different bootloader so they are not considered Uno compatible (and have slightly different hardware). But both boards use the ATMega328 and so should be compatible. There will always be a few differences including ATMega328s not being able to run at 16MHz at 3.3V (and still be in spec).

  • Depends on what you want to do, and while very helpful majors and degrees are not required for most positions. Feel free to check out out job postings if you want to apply.

  • Thanks, fixed
