Description:The Arduino Esplora is a microcontroller board derived from the Arduino Leonardo. The Esplora differs from all preceding Arduino boards in that it provides a number of built-in, ready-to-use setof onboard sensors for interaction. It's designed for people who want to get up and running with Arduino without having to learn about the electronics first. For a step-by-step introduction to the Esplora, check out the Getting Started with Esplora guide.

The Esplora has onboard sound and light outputs, and several input sensors, including a joystick, a slider, a temperature sensor, an accelerometer, a microphone, and a light sensor. It also has the potential to expand its capabilities with two Tinkerkit input and output connectors, and a socket for a color TFT LCD screen.

NodeMCU ESP8266 is an open-source Lua based firmware and development board specially targeted for IoT based applications. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems and hardware which is based on the ESP-12 module, and like this, it can also be programmed using Arduino IDE and can act as both WiFi Hotspot or can connect to one. It has one Analog Input Pin, 16 Digital I/O pins along with the capability to connect with serial communication protocols like SPI, UART, and I2C. NodeMCU has 128 KB RAM and 4MB of Flash memory to store data and programs. Its high processing power with in-built Wi-Fi / Bluetooth and Deep Sleep Operating features make it ideal for IoT projects. Its applications include prototyping for IoT devices, low powered battery-operated applications, and projects requiring I/O interface with Bluetooth and WiFi capabilities.

The Mega 2560 R3 is an open source precise microcontroller board Successor to the Mega based on the ATmega2560 SMD chip.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.

This Board has 54 digital input/output pins (of which 15 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. Using the board is also very easy, simply connect it to a computer with a USB cable or power it with DC adapter or battery to get started. The Mega 2560 R3 board is compatible with most shields designed for Genuino Uno and the former boards Duemilanove or Diecimila.

This is Dot Led Matrix Module incorporating MAX7219 Driver chip. By using this dot LED module in your upcoming project,  you will be able to add some great cool animation.

The individual module features 8×8 LED’s, each controlled very precisely by the MAX7219 driver to generate the colour pattern you wish. The great advantage of using this is users will have control over all of the 64 LED by just connecting 3 output communication wires to microcontrollers like Arduino etc.

This product has 4 Dot Matrix LED’s cascaded to form a single LED Display to allot more area to the user on the display.

Connecting the two modules is also very easy. Only connect the output pins of the previous breakout board to the input pins of the new module, thus with such arrangement, you can connect as many DOT LED Modules to the Arduino as you wish!!! Great……

The MAX7219 Dot Led Matrix Module is a serial input common-cathode driver that interfaces micro-controllers to LED matrices. All common micro-controllers can be connected to this module by using a 4-wire serial interface. Each output can be addressed without refreshing the entire display. This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects. Only one external register is used to set the segment current of each LED.

Requires only three IO ports can drive a dot! No flashing dot matrix display! Support cascade!
