Pulse Heart Rate Sensor Module

Heart rate data can be really useful whether you're designing an exercise routine, studying your activity or anxiety levels or just want your shirt to blink with your heart beat. The problem is that heart rate can be difficult to measure. Luckily, the Pulse Sensor Amped can solve that problem!

The Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings. Also, it sips power with just 4mA current draw at 5V so it's great for mobile applications.

Simply clip the Pulse Sensor to your earlobe or finger tip and plug it into your 3 *or *5 Volt Arduino and you're ready to read heart rate! The 24" cable on the Pulse Sensor is terminated with standard male headers so there's no soldering required. Of course Arduino example code is available as well as a Processing sketch for visualizing heart rate data.

EBOT RGB LED

The WS2812B (or "NeoPixel") may look like a common 5050-sized (5x5mm) SMD LED, but there’s actually an integrated control circuit embedded inside there too. If you look really hard, you can see the tiny black chip hidden in there, along with minuscule gold wires connecting the chip to the LED. This LED is certainly more than meets the eye! The 'B' at the end of the WS2812 name denotes that these specific LEDs are equipped with and only require FOUR pins instead of SIX!

The LED itself is unlike most RGB (Red/Green/Blue) LEDs. The brightness of each color can be adjusted using a serial string to one of 256 different levels. That means there are 16,777,216 (2563) possible combinations of colors. You can produce any color from white to black (off), or salmon to sienna.

Applications

  • Full-color module, Full color soft lights a lamp strip
  • LED decorative lighting

SparkFun Qwiic Joystick

Now, you can easily add an HID/controller to your project! The SparkFun Qwiic Joystick combines the convenience of the Qwiic connection system and an analog joystick that feels reminiscent of the thumbstick from a PlayStation 2 controller and for that reason it's become a favorite of ours. The only thing that could make it better is a "smart" version, so we made one! With the pre-installed firmware, the ATtiny85 is acts as an intermediary (microcontroller) for the analog and digital inputs from the joystick. This allows the Qwiic Joystick to report its position over I2C. 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 joystick is similar to the analog joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply measured with two 10 kΩ potentiometers, connected with a gimbal mechanism that separates the horizontal and vertical movements. This joystick also has a select button that is actuated when the joystick is pressed down. The SparkFun Qwiic Joystick's I2C address is also software selectable so you can plenty of them to the same bus without any risk of collision!.

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.

MyoWare Muscle Sensor (Genuine)

Using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks... but what if we could take the buttons, levers and joysticks out of the equation? This is the MyoWare Muscle Sensor, an Arduino-powered, all-in-one electromyography (EMG) sensor from Advancer Technologies. The MyoWare board acts by measuring the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. It's that easy: stick on a few electrodes (not included), read the voltage out and flex some muscles!

The MyoWare Muscle Sensor is the latest revision of the Muscle Sensor of old, now with a new wearable design that allows you to attach biomedical sensor pads directly to the board itself getting rid of those pesky cables. This new board also includes a slew of other new features including, single-supply voltage of +3.1V to +5V, RAW EMG output, polarity protected power pins, indicator LEDs, and (finally) an On/Off switch. Additionally, we have developed a few shields (CablePower, and Proto) that can attach to the Myoware Muscle Sensor to help increase its versatility and functionality!

Measuring muscle activity by detecting its electric potential, referred to as electromyography (EMG), has traditionally been used for medical research. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into all kinds of control systems.

SparkFun RFID Reader Breakout (Genuine)

This is a simple breakout board for our RFID readers. The SparkFun RFID Reader Breakout converts the 2mm pins to bread board friendly 0.1" headers. With this ability the ID-3LA, ID-12LA, and the ID-20LA you can solder the reader directly to the breakout board or use the 2mm sockets.

This breakout board's edges actually fit flush within the under side the ID-12LA. The board also works with the ID-20LA, but is smaller than the edges. As stated before each pin of the RFID reader has been broken out including: VCC, READ, D0, D1, FORM, TIR, CP, both ANTs, RES, and GND. We've even added four half-mounting holes to the board to easily secure your project!

The RFID USB Reader is a simple to use, USB to serial base unit for the ID-3LA, ID-12LA, and ID-20LA readers. Simply plug a reader into the headers and attach a miniUSB cable. Open a terminal program of your choice at 9600bps 8N1, then scan your 125kHz ID tag and the unique ID will be shown on the screen. The unit is based on a FTDI chip and comes with a read LED and buzzer.

The ID-12LA is a very simple RFID reader module. It plugs directly into the USB reader to allow you to read RFID tags through a USB connection. Power the module, hold up a card, and get a serial string output containing the unique ID of the card.
