This DTMF Shield is a Dual-tone multi-frequency signaling module decoder for Arduino With it's audio connector you can decode the crazy funny noises common phones make.

Do you make time to talk to your Arduino? Maybe you should! The EasyVR Shield 3.0 is a voice recognition shield for Arduino boards integrating an EasyVR module. It includes all of the features of the EasyVR module in a shield form factor that simplifies connection to the Arduino main board and PC.

The motor shield is based on the L298 , it is a double complete bridge driver designed to drive inductive loads, such as relays, solenoids, DC and stepper motors. 

Bluno Mega 2560 has the numerous ports and abundant features of the Arduino Mega series and adds the Bluetooth 4.0 wireless communication function. It has 54 digital ports , 15 of which can be used as PWM output, 16 analog inputs and 4 UART (hardware serial ports) and uses crystal oscillators imported from 16 MHz.

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.

Shield of relays for Arduino, with 2 channel mechanical relays and with 2 channel MOS switch , providing an easy way for applications low and high voltage control. 

This 4-digit 7-segment shield has 5 buttons that can be used as menu selection buttons or control buttons, using I2C to conduct the digital call.

The Iteaduino Uno is a microcontroller board based on the Arduino UNO.

Grove - Water Atomization is a perfect module to easily develop an atomizer or atomizer module in your applications. With just a few simple steps, you can create a prototype for an atomizer.

It has a Grove interface that makes it easy to integrate with various applications. A humidifier is a basic device with which it can be built, it can develop more advanced and interesting designs with digital aroma technology and any other situations where atomization is necessary.

Uses the NTC Thermistor Sensor, Good Sensitivity. The Clean Waveform of the Comparator Output Signal is Good, Driving Capacity.
