。Description。The SparkFun Continuous Rotation(CR)Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state， the CR Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the CR Servo Trigger， you simply connect a hobby servo and a switch， then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servo in your projects without having to do any programming!。When we introduced the original Servo Trigger， we mentioned that it could be reprogrammed to be more useful with continuous rotation servo motors. But reprogramming the firmware is somewhat tedious， and users asked for a Servo Trigger preprogrammed with the continuous rotation logic. With this little board you will be provided an easy way to deploy continuous rotation servos into your projects!。The heart of the CR Servo Trigger is an Atmel ATtiny84 microcontroller， running a small program that implements the servo control features designed for continuous rotation servos. On board each of these CR Servo Triggers you will find three potentiometers："A" sets the position the servo sits in while the switch is open， "B" sets the position the servo moves to when the switch is closed， and "T" sets the time it takes to get from A to B and back.。Compared with a servo motor， the CR Servo Trigger board draws very little current， roughly 5mA at 5V. Be sure to note that if you're using the CR Servo Trigger to control your motor， the absolute maximum supply voltage that should be applied is 5.5 VDC. Additionally， the SparkFun CR Servo Trigger is designed to make it easy to daisy chain boards - you can simply connect the VCC and GND pads on adjacent boards to each other.。Note：This idea originally came from our friend in the Oakland area， CTP. If you see him， please give him a high-five for us.。SparkFun CR Servo Trigger Hookup Guide。Features。Recommended Voltage：5VDC。Max Voltage：5.5VDC。Current Draw：5mA。Control Continuous Rotation Servos。Three Control Settings。A - sets the position the servo sits in while the switch is open。B - sets the position the servo moves to when the switch is closed。C - sets the time it takes to get from A to B and back。Easy Control with Potentiometers。Configurable Input Polarity。Configurable Response Mode。Compatible with Analog Servos。ISP Header Pins Available for Reprogram

The two large， exposed pads function as probes for the sensor， together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be， resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.。To get the SparkFun Soil Moisture Sensor functioning， all you will need is to connect the VCC and GND pins to your Arduino-based device(or compatible development board). You will receive a SIG out， which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist environment. To combat this， we've had the PCB coated in gold finishing(ENIG， or Electroless Nickel Immersion Gold).。Note：Check the Hookup Guide below for assembly and weatherproofing instructions， as well as a simple example project that you can put together yourself!。Get Started with the Soil Moisture Sensor Guide

Description。The Teensy is an amazing and compact development platform in breadboard friendly form factor， but what if you could incorporate it into the Arduino architecture? The Teensy Arduino Shield Adapter allows you to attach your Teensy and utilize your favorite Arduino shields without the requirement of breadboard or any complicated wiring. Needless to say， the Teensy Arduino Shield Adapter is useful tool for upgrading all of your existing Arduino projects to more powerful controller!。As we stated before， the Teensy Arduino Shield Adapter provides basic Arduino compatibility with your run-of-the-mill shield but there are few other fun features that we've added on， as well. These features include Real Time Clock(RTC)battery， JST battery connector， 4-12V barrel jack connector， an ICSP header， and more. Because this board is simply an adapter， there is no special programming required to start working with the adapter. You will， however， need to program the Teensy for any Arduino shield you'd like to work with.。While the adapter design can fit the Teensy LC footprint， it has been designed to fully utilize the features of the Teensy 3.1. Not all of the features available on the adapter are compatible with the LC so please be sure to check the Hookup Guide in the。Documents。section below to ensure functionality for your project. Please keep in mind that this adapter may be incompatible with some 5V Arduino shields. Please check our hookup guide for more information.。Note：The Teensy Arduino Shield Adapter comes as kit and will need to be soldered together.。Note：Due to the requirements of shipping the batteries in this kit， orders may take longer to process and therefore do not qualify for same-day shipping. Additionally， these batteries can not be shipped via Ground or Economy methods to Alaska or Hawaii. Sorry for any inconvenience this may cause.。Features。Arduino R3 Interface。Real Time Clock Battery。JST Battery Connector。Barrel Jack。I2C Jumpers。ICSP Header。DAC Pin Header

Description。The LilyMini ProtoSnap is a great way to get started learning about creating interactive e-textile circuits before you start sewing. Like other LilyPad ProtoSnap boards， the LilyMini ProtoSnap has all of its pieces wired together out of the box， enabling you to test the circuit's function before you sew. At the center of the board is a pre-programmed LilyMini microcontroller connected to a LilyPad Light Sensor， LilyPad Button and two pairs of LilyPad LEDs.。The LilyMini ProtoSnap ships with pre-loaded code that uses all the LilyPad pieces connected to it. This sample code has three modes， which can be selected by pressing the LilyPad Button on the bottom-left side of the ProtoSnap. The built-in RGB LED on the LilyMini will change color to indicate which mode has been selected：。White：。All LEDs on.。Magenta：。LEDs fade in and out in a breathing pattern. When the light sensor is covered， LEDs fade faster.。Cyan：。LEDs off. When the light sensor is covered， LEDs will twinkle.。The LilyMini board， at the center of the ProtoSnap， has a built-in battery holder for a CR2032 battery(included). On the opposite side of the LilyMini you will find the SAMD11 brain， which controls the ProtoSnap.。Note：。A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.。Note：。The LilyPad LilyMini ProtoSnap does NOT include sewing needles or conductive thread. These items will need to purchased separately.。Warning：You cannot reprogram this product and any attempt at programming is at your own risk!。Get Started with the LilyMini ProtoSnap Guide

Description。The Raspberry Pi 4 Desktop Kit includes everything you need to turn any monitor with an HDMI port into a desktop PC. A 64GB MicroSD card provides the capacity and speed needed to run most operating systems for the Raspberry Pi platform smoothly. The USB Type C wall adapter and Type-C to Type-C cable provide a modular power system for the Raspberry Pi 4. The heat sink case provides protection for the Raspberry Pi Board but also cools the major components allowing it to run smoothly during heavy usage. The Logitech K400 keyboard provides a plug and play HID solution for the system. Finally， we've included both an HDMI to Micro HDMI cable to interface to any HDMI monitors and our Qwiic Shim which allows for easily attaching any of our Qwiic Boards for adding another level to your desktop setup.。If you're looking to create a PC or Media Center with the Raspberry Pi 4， this is the kit for you. All the components were chosen and vetted to create the highest quality， least frustrating experience that allows the Pi to work to its full potential. The new 64GB card has blazing fast read write speeds that brings updates from half an hour down to 3 minutes when compared to our previous card. You'll struggle to find a more plug and play kit for the Pi that allows you to load the operating system of your choice.。Note：The Qwiic Shim is not intended to be used with the Heatsink case， as it prevents the case from properly connecting with the processor. The top of the case needs to be off should you use the Shim or utilize an extension header in conjunction with a Pi Hat.。The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.。Get Started with the Raspberry Pi 4 Model B Guide
