。Description。Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer(e.g. Flash， Processing， MaxMSP). The open-source IDE can be downloaded for free(currently for Mac OS X， Windows， and Linux).。The Arduino Mega is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins(of which 14 can be used as PWM outputs)， 16 analog inputs， 4 UARTs(hardware serial ports)， a 16 MHz crystal oscillator， a USB connection， a power jack， an ICSP header， and a reset button. It contains everything needed to support the microcontroller； simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.。Never fear for accidental electrical discharge， either since since the Mega also includes a plastic base plate to protect it!。The Mega 2560 R3 also adds SDA and SCL pins next to the AREF.。In addition， there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board.。The other is a not connected and is reserved for future purposes.。The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.。Not sure which Arduino or Arduino-compatible board is right for you?

Description。Are you low on I/O? No problem! The SX1509 Breakout is 16-channel GPIO expander with an I2C interface that means with just two wires， your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals， so you can dim LEDs. It can be set to blink or even breathe pins at varying rates. This breakout is similar to multiplexer or "mux，" in that it allows you to get more IO from less pins. And， with built-in keypad engine， it can interface with up to 64 buttons set up in an 8x8 matrix.。Two headers at the top and bottom of the breakout board function as the input and control headers to the board. This is where you can supply power to the SX1509， and where your I2C signals SDA and SCL will terminate. GPIO and power buses are broken out in every-which direction， and configurable jumpers cover most of the rest of the board.。Since the I/O banks can operate between 1.2V and 3.6V(5.5V tolerant)independent of both the core and each other， this device can also work as level-shifter. The SX1509 breakout makes it easy to prototype so you can add more I/O onto your Arduino or I/O limited controller.

。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

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 SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor， utilizing two chips from Maxim Integrated：the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing， the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations， digital filtering， pressure/position compensation， advanced R-wave detection， and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small， measuring at 1in×0.5in(25.4mm×12.7mm)， which means it will fit nicely on your finger without all the bulk.。The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation(SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point. To get the most out of the sensor we've written an Arduino Library to make it easy to adjust all the possible configurations.。The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.
