DescriptionThe SparkFun Inventor's Kit(SIK)for Arduino Uno is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete five overarching projects consisting of 16 interconnected circuits that teach everything from blinking an LED to reading sensors. The culminating project is your very own autonomous robot! No previous programming or electronics experience is required to use this kit.The online guide contains step-by-step instructions with circuit diagrams and hookup tables for building each project and circuit with the included parts. Full example code is provided， new concepts and components are explained at point of use， and troubleshooting tips offer assistance if something goes wrong.The kit does not require any soldering and is recommended for beginners ages 10 and up who are looking for an Arduino starter kit. For SIK version 4.1 we took an entirely different approach to teaching embedded electronics. In previous versions of the SIK， each circuit focused on introducing a new piece of technology. With SIK v4.1， components are introduced in the context of the circuit you are building， and each circuit builds upon the last， leading up to a project that incorporates all of the components and concepts introduced throughout the guide. With new parts and a completely new strategy， even if you've used the SIK before， you're in for a brand-new experience!This version of the SIK replaces the SparkFun RedBoard Qwiic with the Arduino Uno(SMD version)and comes without the SIK guidebook and carrying case. With these components being swapped and removed， we were able to reduce the overall size and weight of the kit， making shipping cheaper and easier for anyone ordering internationally.Note：As stated above， this SIK does NOT include a carrying case or print guidebook.Get Started With the SparkFun Inventor's Kit v4.1 Experiment GuideExamplesProject 1：LightCircuit 1A：Blinking an LEDCircuit 1B：PotentiometerCircuit 1C：PhotoresistorCircuit 1D：RGB Night-LightProject 2：SoundCircuit 2A：BuzzerCircuit 2B：Digital TrumpetCircuit 2C："Simon Says" GameProject 3：MotionCircuit 3A：Servo MotorsCircuit 3B：Distance SensorCircuit 3C：Motion AlarmProject 4：DisplayCircuit 4A：LCD "Hello， World!"Circuit 4B：Temperature SensorCircuit 4C："DIY Who Am I?"

DescriptionDo you want to replace a slider or a button on your art project or science experiment with a more interesting interface? This Capacitive Touch Slider is a "Qwiic" and easy way to add capacitive touch to your next project. With the board's built in touch pads， you can immediately start playing with the touch capabilities as three unique touch inputs or as a slider. You can also enable a touch input to act as a power button， customize the sensitivity for your own touch pads， and play with the interrupt alert LED. Utilizing our Qwiic system， no soldering is required to connect it to the rest of your system. However， we have broken out 0.1"-spaced pins in case you prefer to use a breadboard or create your own touch pads.On the front of the board， there is an arrow shape which contains three separate capacitive touch pads. We also broke out the capacitive touch sensor lines as plated through-holes on the top of the board. You can use these pins to connect to your own capacitive touch pads. The CS1 pin connects to the left pad， the CS2 pin connects to the middle pad， and the CS3 pin connects to the right pad.NOTE：The I2C address of the CAP1203 is 0x28 and is hardware defined. A multiplexer/Mux is required to communicate to multiple CAP1203 sensors on a single bus. If you need to use more than one CAP1203 sensor consider using the Qwiic Mux Breakout.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 SparkFun Capacitive Touch Slider GuideFeaturesCapacitive Touch3 unique capacitive touch inputsFeaturesEmulated sliderPower button settingProgrammable sensitivityAutomatic recalibrationI2C Address：0x28Qwiic EnabledOperating RangeSupply Voltage：3.3V - 5V

DescriptionGet with the times， already! This SparkFun Real Time Clock(RTC)Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power(running at only about 22nA in its lowest power setting)so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the "battery." To make it even easier to get your readings， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system so 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.This RTC module's built in RV-1805 has not one， but two internal oscillators：a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.There is also the option to add a battery to the board if the supercapacitor just isn't going keep your project powered long enough(keep in mind， the supercap can hypothetically make the board keep time for around 35 days)， you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour/minute/second/date will be maintained.Note：The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus. If you need to use more than one RV-1805 sensor consider using the Qwiic Mux Breakout.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionThe SparkFun MicroMod Environmental Function Board adds additional sensing options to the MicroMod Processor Boards. This Function Board includes three sensors to monitor air quality(SGP40)， humidity temperature(SHTC3)， and CO2 concentrations(STC31)in your indoor environment. To make it even easier to use， all communication is over the MicroMod's I2C bus!The SGP40 measures the quality of the air in your room or house. The SGP40 uses a metal oxide(MOx)sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound(VOC)based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.The SHTC3 is a highly accurate digital humidity and temperature sensor. The SHTC3 uses a capacitive humidity sensor with a relative humidity measurement range of 0 to 100% RH and bandgap temperature sensor with a temperature measurement range of -40℃ to 125℃. The SHTC3 builds on the success of their SHTC1 sensor with higher accuracy(±2% RH， ±0.2℃)than its predecessor， enabling greater flexibility.The STC31 measures CO2 concentrations based on thermal conductivity and has two CO2 measurement ranges：0 to 25 vol%； and 0 to 100 vol%. The measurement repeatability is 0.2 vol%， with a stability of 0.025 vol% / ℃. The measurement accuracy depends on the measurement range：0.5 vol% + 3% measured value； 1 vol% + 3% measured value. Using measurements from the SHTC3， the STC31 is able to provide humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if， like us， you're up in the mountains!The outstanding performance of these three sensors is based on Sensirion's patented CMOSens(R)technology， which combines the sensor element， signal processing， and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.Utilizing our handy M.2 MicroMod connector， no soldering is required to connect it to your system. Simply match up the key on your processor and function board's beveled edge connector to their respective key on the M.2 connector， then secure them to the main board with screws. The MicroMod Environmental Function Board can then be read via the I2C port. The board is equipped with the AP2112 3.3V voltage regulator， I2C pull-up resistors， power LED， jumper to disable the LED， and jumpers for alternative STC31 addresses.Note：A MicroMod Processor and Main Board are not included with this MicroMod Environmental Function Board. These boards will need to be purchased separately.MicroMod is a modular interface ecosystem that connects a microcontroller "processor board" to various "carrier board" peripherals.

DescriptionThe SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits! We have designed the SparkFun Line Follower Arrays to follow a dark line of about 3/4 inch width or smaller(spray paint or electrical tape)on a light background. Each array features visible LEDs that point upward when the board is attached(properly)so you can see what the robot sees， brightness control right on the board， and an I2C interface for reading and power control. Here at SparkFun， the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot.The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about 1/4 to 3/4 inches away. The IR brightness control and indicator can be adjusted with the on-board potentiometer and is capable of showing you the strength of the IR LEDs. Illumination can be turned on and off with software to conserve power， or left on all the time for faster readings. The SparkFun Line Follower Array requires 5V of power with a supply current range of 25-185mA with strobing disabled and 16-160mA with it enabled. Additionally we have added six mounting holes to the line follower with the two inner holes designed to fit our Shadow Chassis while the other four are general purpose.Note：As you know our Sun emits quite a bit of infrared light， making the SparkFun Line Follower Array much less effective in direct sunlight. Plan your projects accordingly!Features8 sensor eyes(QRE1113， like in our line sensor breakout)I2C interfaceAdjust IR brightness on the fly with a knobSwitch IR on and off with softwareSwitch visual indicators on and off with softwareInvert dark/light sight with softwareBased on the SX1509 I/O expander
