。Description。The 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 Guide。Examples。Project 1：Light。Circuit 1A：Blinking an LED。Circuit 1B：Potentiometer。Circuit 1C：Photoresistor。Circuit 1D：RGB Night-Light。Project 2：Sound。Circuit 2A：Buzzer。Circuit 2B：Digital Trumpet。Circuit 2C："Simon Says" Game。Project 3：Motion。Circuit 3A：Servo Motors。Circuit 3B：Distance Sensor。Circuit 3C：Motion Alarm。Project 4：Display。Circuit 4A：LCD "Hello， World!"。Circuit 4B：Temperature Sensor。Circuit 4C："DIY Who Am I?"

。Description。These are our small， beefy aluminum enclosures， which have been built tough enough to withstand a truck. This 2mm-thick， die-cast enclosure is rated IP54 against dust and splashing water. Because it's aluminum， it's easy to cut and drill so that you can add LCD screens， buttons and cable connections. If you want to "pretty up" your project， hit this with some fine-grit sand paper and buff it or just spray paint it!。These enclosures are perfect for producing "stomp box" style effects pedals. Try combining this with a stomp switch and some of your own secret sauce circuitry to build a sweet custom pedal.。The lid mates nicely to the top of the enclosure and is secured with 10mm long #6-32 screws(included). This aluminum enclosure version features a smoother metal finish as well as a more structurally sound design.。Features。112x61x31mm

Carbide Copper is CAM software to let you mill PCBs with your CNC machine and is the fastest way to make same-day circuit boards in your own office or shop.。Note：It is recommended to use this PCB engraver with FR1 copper clad rather than FR4 to ensure you give your tool bit the longest life possible.。Features。0.005" Ball tip(0.0025" radius)。40 Degree Tip Angle。0.125" Shank。2 Flutes。Solid Carbide

Description。The SparkFun Qwiic Dual Solid State Relay is a power delivery board that allows users to switch two AC loads from a low power microcontroller using the SparkFun Qwiic connect system. The board features two 25A/250VAC solid state relays that utilize the Zero Cross Trigger method so you can toggle two loads on a 60Hz AC carrier signal on and off up to 120 times per second!。An ATTiny84 acts as the "brain" of the SparkFun Qwiic Dual Solid Relay to accept I2C commands to toggle the two relays as well as a few other special commands. The I2C address of the ATtiny84A is software configurable so， if you have a seriously big power project in mind， you could daisy chain over 100 Qwiic Dual Solid State Relays.。Messing with such high voltage is dangerous! We've included many safety precautions onto the PCB including ground isolation between the relay and other circuitry and a milled out area isolating each side of AC. However， with all the safety precautions included with the SparkFun Qwiic Dual Solid State Relay， this is still a power accessory for users who are experienced around， and knowledgeable about high AC voltage. If you're not comfortable with handling AC voltage in this way， you may want to check out the IoT Power Relay instead.。Note：The relays are rated for a max of 25A with forced air cooling. If you do not have forced air cooling， 10A max through the relays is recommended.。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 Qwiic Dual Solid State Relay Guide。Features。Operating Voltage：2.5-3.6V(3.3V recommended)。I2C Address：0x0A(Default)0x0B(Alternate via jumper select)。Load Voltage Range：12-280VAC。Max Current(Through Relay)：25A(240VAC with forced air cooling)。Zero Cross Trigger。Normally Open Circuit Only。2x Qwiic Connector
