Description。The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. 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 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

It can also be used for general serial applications.。This board still brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto-reset any Arduino board that has the reset pin brought out to a 6-pin connector.。The coolest thing about the FT231X Breakout is that we have broken out ALL the pins for your use， making this board all the more hackable! It also uses a common microUSB jack.。One of the features of this board is a jumper on the back， which allows the VCC output to be configured to either 3.3V or 5V. This board ships default to 5V， but you can cut the default trace and add a solder jumper if you need to switch to 3.3V. It should be noted that the max input of the FT231X is only 3.3V， but it can operate down to 1.8V with external pull-ups and is also 5V tolerant.

。Description。The SparkFun Qwiic TMP117 breakout is a high precision temperature sensor equipped with an I2C interface. It outputs temperature readings with high precision of ±0.1℃ across the temperature range of -20℃ to +50℃s with no calibration and a maximum range from -55℃ to 150℃. The SparkFun High Precision Temperature Sensor also has a very low power consumption rate which minimizes the impact of self-heating on measurement accuracy. Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.。The SparkFun High Precision Temperature Sensor also includes programmable temperature limits， and digital offset for system correction. While the TMP102 is capable of reading temperatures to a resolution of 0.0625℃ and is accurate up to 0.5℃， the on-board TMP117 is not only more precise but has a 16-bit resolution of 0.0078℃!。To make this breakout even easier to use， we've written an Arduino library to help you get started "Qwiic-ly." Check the Documents tab above for more information.。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.。The TMP117 High Precision Temperature Sensor can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system. No programming， soldering， or setup required!。Need a custom board? This component can be found in SparkFun's A La Carte board builder.

。Description。The SparkFun Wireless Joystick Kit provides an easy way to control your next XBee project. Before the wireless joystick， radio-controlled projects used hobby RC transmitters， the same ones used for RC cars， boats and planes. The problem with these transmitters is that many aren't customizable， and the ones that are tend to be too expensive for many of us. The Wireless Joystick Kit offers a custom wireless solution for those who want to control their project their own way.。Equipped with the increasingly popular SAMD21 onboard， all you need is to assemble the SparkFun Wireless Joystick into the configuration you want and add your own XBee and lithium ion battery into the provided sockets. The Wireless Joystick Kit can be assembled into a configuration that utilizes dual joysticks for better RC steering robots(like tanks)or a single joystick configuration with four 12mm momentary pushbuttons(a setup similar to what older game consoles used). We have provided a full Hookup Guide that gives assembly instructions， as well as a tank-steering motor controller tutorial to help get you started!。Please be aware that the SparkFun Wireless Joystick Kit is。NOT supported on Windows 7/8。due to a lack of support drivers for those specific OS's.。Note：This kit will need to be assembled before use， so a beginner's knowledge of soldering will be required. Additionally， in an effort to keep shipping rates down and make this kit available to people throughout the world without delay， there is no XBee or lithium ion battery included.。Get Started with the Wireless Joystick Kit Guide
