  • LilyTwinkle

    The LilyTwinkle is a tiny little LilyPad board designed to add some twinkle to your project. Even though it's as small as some of the LilyPad sensors, this board actually has an ATtiny microcontroller on it so it's actually pretty smart! Simply sew on 4 LEDs and connect a battery and the LEDs will twinkle-fade (a lot like fireflies... or lightning bugs, if that's what you call them). LilyTwinkle is a quick and easy way to add twinkling lights to a project without any programming or a bulky Main Board.

    If you're an advanced user and want to re-program the LilyTwinkle, the ICSP programming connectors are broken out on the back.

  • LilyPad Arduino SimpleSnap

    The LilyPad SimpleSnap is a new, easy way to create e-textiles projects with LilyPad that are modular and can be disassembled or broken down, it's also a great way to prototype! The SimpleSnap board is similar to the LilyPad Simple board, and has the same functionality except for two major differences: A built-in rechargeable Lithium Polymer battery and female snap connectors. By adding fabric snaps to the board, LilyPad's made it possible to connect this board to the SimpleSnap Protoboard or simply an arrangement of sew-on fabric snaps so that the board is removable from your project for washing or so that multiple projects can share a board! It is important, though, that you do not wash the SimpleSnap because the battery can be damaged.

    The on-board Lithium Polymer battery can be charged simply by attaching an FTDI breakout (the same board used for programming) and just like the Simple, the SimpleSnap can be programmed in Arduino!

    LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!

  • RedBot Buzzer

    This buzzer is an add-on for your RedBot that gives your robot the ability to make awesome beep-boop noises or alerts when something interesting (or terrible) happens. The buzzer works by making use of two I/O pins on a controller board to create different noises based on the different frequency of I/O toggling. If you are using this buzzer on a RedBot, simply plug it in to one of the many 3-pin I/O ports and get your robot to make some noise.

    The buzzer has a 3-pin header which connects directly to the RedBot Mainboard or via male to female jumper wires. Use the included RedBot library to detect sound alarms and make some noise.

  • Vernier Interface Shield

    This is the Vernier Interface Shield, a simple add-on to give your Arduino the capability to interface with Vernier sensors. Attached to this interface shield are four British Telecom sockets (2 Analog, 2 Digital) which all Vernier sensors use as connectors. Like any other shield, simply attach it to an Arduino development platform. This shield was developed to be used with the Arduino Uno platform but will still work with other Uno equivalents like the Leonardo or SparkFun RedBoard.

    Vernier Software and Technology has been a leader in data collection and analysis for educators world-wide. They were amongst the first companies to design and promote the use of computers, sensors, and data collection in K-12 classroom laboratory experiments.

  • Magnetic Snap 18mm

    A snap is fun, but a magnetic snap adds a whole new layer of possibilities. This are relatively large 18mm diameter snaps (all three pieces come as shown). They couple together very strongly (must be pried apart), rotate freely on the axis, and are electrically conductive. We've seen snaps like these soldered onto PCBs and batteries to form a strong, but quick disconnect mechanism. Overall connection resistance is less than 200 miliOhm. Snaps will couple when closer than 10mm.

  • LilyPad Buzzer

    This is a small buzzer for the LilyPad system. Use 2 I/O pins on the LilyPad main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud.

    Please note: This is an inductive buzzer meaning that is will act as a short to ground if you are not actively driving it. We recommend you put both I/O pins to low (0V) when the buzzer is not used. Also, it's come to our attention that washing these buzzers will damage them. Until we've figured out a solution to this, avoid washing any portion of your project that contains one of these buzzers.

  • CMUcam v4

    Retired product, with no replacement. Limited to stock on hand.

    Computer vision is seriously cool technology but it takes a lot of processing power, it'd be nice to give your next microprocessor project the power to identify motion and color, but something like an Arduino would struggle to keep up. What you can do is have a dedicated processor do the heavy-lifting and then pipe that data to the Arduino, and that's exactly what the CMUcam4 does. The CMUcam4 is a fully programmable embedded computer vision sensor. The main processor is the Parallax P8X32A (Propeller Chip) connected to an OmniVision 9665 CMOS camera sensor module.

    The CMUcam4 can be used to track colors or collect basic image statistics. The best performance can be achieved when there are highly contrasting and intense colors. For instance, it can easily track a red ball on a white background, but it would be hard to differentiate between different shades of brown in changing light. Tracking colorful objects can be used to localize landmarks, follow lines, or chase moving beacons. Using color statistics, it is possible for the CMUcam4 to monitor a scene, detect a specific color, or do primitive motion detection. If the CMUcam4 detects a drastic color change, then chances are something in the scene changed. Using “line mode”, the CMUcam4 can generate low resolution binary images of colorful objects. This can be used to do more sophisticated image processing that includes line following with branch detection, or even simple shape recognition. These more advanced operations require custom algorithms to post process the binary images sent from the CMUcam4. As is the case with a normal digital camera, this type of processing might require a computer or at least a fast microcontroller.
