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.

Installing an Arduino Bootloader

This tutorial will teach you what a bootloader is, why you would need to install/reinstall it, and go over the process of doing so.

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.
  • That is the price for a regular customer. If you had an educator account the price you would see when logged in is in the $700 range. In other words if you are not an educator you probably shouldn’t buy this. If you are an educator then the pricing makes sense.

  • Yes, it is 2 per order, you can place as many orders of 2 as you’d like. It is a shipping thing so no outgoing shipment can have more than 2. It is a pain and we are working on fixing it.

  • Basically when we’ve collected enough junk we box things up, announce it and grab some popcorn to watch the show. In the past we’ve sold out within 5 minutes, so it can be a bit of a mad house.

  • There have been a log of comments on the ESP8266 Thing about lack of FTDI. The problem with FTDI is the price. We sell the FTDI basic for $15, so in theory adding it on would basically double the price. You can always connect it permanently, but we figure most people won’t want to. I’d still check out the board. It’s not an Arduino/ATMega328 based board, but it is programmable in the Arduino IDE using the FTDI basic board (or similar USB to UART adapter).

  • They are in many ways 2 different markets. See mjkuwp’s comment, but one is designed to be a cloud programmable device. One of the main uses for this was manufactures to put these in devices so they could remotely update firmware. So definitely pricey if you want an ESP8266, but not so bad if you want an Electric Imp.

    I like the ESP8266. I’d vote for leaving off the ATMega328, having access to UART, 6GPIOS, and an ADC with a built in Lipo charger and port. All that for $15-$16 would be a pretty cool thing.

  • It looks like this is basically just 4 switches. Generally with a switch you have 2 connections and when the switch is pressed those 2 connections get shorted together (sometimes you will have a 3rd connection which is shorted when the switch is not pressed, this is usually called a NO or normally open contact). Usually when hooking a switch up to an Arduino you connect 1 end to GND and the other to an input pin. This allows you to check if that input pin is connected to ground. You also want to make sure that when it is not pressed that it shows up as high. Generally this is done with a pullup resistor (a resistor, usually around 10k, that is connected to VCC). The Arduino does provide internal pullup resistors on pins if you want to use them, just make sure they are turned on. You do not want to connect this directly to VCC! If you do when you press the switch you have just connected VCC directly to GND. If you have any other questions feel free to email techsupport@sparkfun.com

  • It is the new Labview Home Edition. If you want to find out more about it I’d recommend checking out the getting started guide. Follow the directions for the download and just skip the section where you enter the serial number. There is a free trial that lets you play with the software and if you decide to get it you can just add the serial number in once you get it.

  • I tend to point people in the project oriented answer. The SIK is good at giving you a brief overview, but rarely do people learn electronics because they are bored and are trying to fill up brain space. It is usually because they have something in mind. That something might be generic like “I’d like to learn to build robots” or more specific like “I want to build a weather station that posts information to my webpage”. In both instance I’d say start with a part or parts and start learning how to add them into what you already know. Whether that is motors and motor drivers, weather sensors, or wireless. Start looking and products, their descriptions, and the example Arduino code. Then ask lots of questions (in the comments, in forums, to friends, to our techsupport). Once you have the basics find something you want to do, it will help keep you motivated and give you a sense of accomplishment once you’ve finished.

  • That it is. Keep in mind that the Arduino bootloader is already on the chip so you can also just use the FTDI header to upload new code.

  • It depends on your power supply. Some are center positive and some are center negative. Your best bet is to grab a multimeter and see which part of the input is shorted to which of the output pins.
