Leonardo R3 Board Micro-USB compatible with Arduino

The Leonardo R3 Board Micro-USB compatible with Arduino is a micro-controller board base on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs);  a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

It contains everything need to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

The Leonardo R3 Board differs from all preceding boards in that the ATmega32u4 has built-in USB communication; eliminating the need for a secondary processor.

This allows the Leonardo to appear to a connected computer as a mouse and keyboard; in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board.

Mega 2560 is an Arduino board based on ATmega2560. It is one of the most advanced ATmega based Arduinos in terms of processor. It has 54 digital I/O pins. 14 of them can be used as PWM outputs. It has 16 analog inputs, 4 UART (serial ports), 16 MHz crystal oscillator, USB connection, adapter input, ICSP output and a reset button. With the Mega 2560 R3 model, the 16U2 model was used instead of the 8U2 model in the previous versions. In this way, faster data transfer is achieved using less memory. 
It is compatible with all shields designed for Arduino Duemilanove and Diecimila. Thanks to more pins, we can use this advanced processor in many projects such as 3D printers that we cannot do with entry-level Arduinos such as Uno. Arduino Mega 2560 R3 is the latest model of Arduino Mega. It supports all the features found in previous models. 

Arduino Mega 2560 can be powered from USB and an external adapter or battery. The power source is selected automatically. The board can be fed from an external source between 6-20V. If the supply is below 7V, the 5V output pin cannot give 5V and the board may work unbalanced. If an external power source higher than 12V is used, the voltage regulator may overheat and damage the board. It is recommended to use 7-12 Volts.

It is an open source development platform. You can easily program microcontrollers with Arduino libraries. Thanks to its analog and digital inputs, you can process analog and digital data. You can easily design systems that can interact with its environment. You can design systems by processing the received data using sensors. You can make new hardware with the outputs of the systems you designed.

1. The latest Sensor Shield V5 Expansion Board For Arduino is produced by ALSRobot. This Sensor Shield expansion board to retains the advantages of version V4.0 on the basis of stack design, PCB Immersion Gold processing technology. newly added many kinds of interface, for example, IIC interface, 32 channels servo motor interface, Bluetooth communication module interface, SD Card communication module interface and so on, more convenient. Sensor Shield allows you to connect to various modules like sensors, servos, relays, buttons, potentiometers and many more directly to your Arduino through this Sensor Shield. Each functional module has buckled port with VCC, GND, and Output, which has the corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking. You can easily connect with usual analog sensors by using this expansion board, such as ray sensor. If you support by this expansion board and the corresponding circuit module, you only need to combine Arduino and sensors module by using special cables, because concrete circuit details achieve by corresponding sensors module, so you only need to consider that how to read data coming from the sensor by the program in Arduino. For Arduino beginners, you do not have a headache for the cumbersome and complex circuit connection, the sensor extends the true sense of the board to simplify the circuit which can easily connect the commonly used sensor, a sensor requires only a common 3P sensor cable (regardless of digital cable and analog cable), after the completion of the circuit connection, the preparation of the corresponding Arduino program downloaded to the Arduino Duemilanove controller reads the sensor data, or receive wireless module to return data after computing the final easy to complete your own interactive works.
