WiDo is a WIFI IoT Node development board compatible with Arduino.

This version of the Ethernet Shield is not only compatible with Mega 1280 and 2560, but also provides a Micro SD card slot for read / write

This relay shield is capable of controlling 4 relays . The maximum switching power can be 360VA / 90W . It can be controlled directly by the Arduino by means of digital IOs digital with external power of 9v . With integrated xbee socket and APC220 socket, it can be controlled wirelessly via Xbee / bluetooth / APC220 . Make it an ideal solution for home automation and robotics.

This module is based on the popular L298N H Bridge DC Motor Driver . The circuit will allow you to easily and independently control two motors up to 2A each in both directions.

8 relay module with ports " NC " means " Usually connected to COM " and ports "NO" means " Usually open to COM ".

BTBee Pro is a Bluetooth serial port module that can be compatible with shields that have XBee socket.

Play your .mp3 files stored by USB or SD card. For Use (12V): Place a 68Ohm/1W Resistor in series with the (+) of the Power Supply, to avoid excessive dissipation.

This LED Matrix 24 × 8 display is specially designed for the FireBeetle series. It supports low power mode and scroll display. With HT1632C high-performance LED driver chip , each led has an independent register, which facilitates separate driving. Integrates a 256KHz RC clock, only 5uA in low power mode, supports 16-scale PWM brightness adjustment. This product also works with another Arduino microcontroller like Arduino UNO (same as DFRduino UNO).

Can be used to monitor the heart rate of the patient and athlete. The result can be displayed on a screen via the serial port and can be saved for analysis.

Now, it's time to add a more sophisticated interactive way to your project. The DFRobot touch kit comes with three types of touch sensors . A ipod styple touch wheel, a touch touch screen that supports backlit and a grid touch pad that can recognize something unique.

This is the FeatherWing Adalogger: it adds a real-time clock with battery and micro SD card storage to any Feather mainboard. Using the Headers, you can connect a FeatherWing to the top of your board and let the board fly!

The 8 Environment Sensors Kit, M5Stack Env Kit, includes the 8 Earth, Angle, Pir, Hub, Light, Rgb, Ir and Env Sensors.

Finger is a fingerprint sensor that makes fingerprint verification super simple.

The Uart protocol, compact size and ultra low power consumption make the use of MSStack series products very attractive. It performs fast fingerprint matching with the highest level of security and the ideal convenience of the user. You can program to set the level of comparison of the fingerprint recognition and the different security level. If you've ever thought about protecting your project with biometrics, don't forget to include this MSunit Finger.

This unit communicates with the M5Core by UART protocol connected via PORTC.

When you assign a high level to the module pin, the electro magnet can suck magnetically conductive objects. Otherwise, it will release the object.

An electro magnet is a type of magnet in which the magnetic field is produced by electric current. An electric current flowing in a wire creates a magnetic field around the wire, due to the Ampere Law. To focus the magnetic field on an electro magnet, the wire is wound into a coil with many twists of wire side by side. The Magnetic Field of All Twists of the Wire passes through the Coil Center, creating a Strong Magnetic Field there.

It's Easy to Use to Learn the Electro Magnet Principle.

This UV Sensor is capable of detecting UV solar radiation using a simple UVM-30A chip. It can be easily configured for projects with Arduino to monitor UV Index, analyze UV-A lamps or DIY projects as plant growth analysis.

Kit Thermostat with LED Indicator - Velleman.

This Shuck Socket it is easy to use and to install.
