Introduction to Arduino Zero
- Arduino Zero is a microcontroller board, based on Atmel SAMD21G18U ARM CORTEX MO+CPU. It is simply a 32 bit extension of Arduino UNO series.
- It has 20 input-output pins (10 can be used PWM output), it also has six analog inputs, 2 UARTs, 48 MHZ clocks, 1 digital to analog converter (DAC), one SPI reader, one TWI and reset button.
- One of the most important functions of it is that (EDGB), Which provide full debugging without any external hardware. EDGB also support a virtual com port that can be used for boat loader programming.
- It allows the designer to control electronic devices in a comprehensive way. AC to DC adopter can also be used to power the board.
- It can operate on external supply 6 to 20 volts. But if we supply below six volts it becomes unstable and if the voltage is greater then 12, the voltage regulator is overheating and may damage the board.
Arduino Zero PINOUT & DescriptionThere are main twenty pinouts of Arduino Zero, let's discuss which are most important and mostly used.
|01||SCL||SCL is a clock line. It uses to synchronized data on a protocol which it uses. It works on the I2C protocol.|
|02||SDA||SDA is a line at which data is transferred by the serial way.|
|03||AREF||AREF stand for Analogue reference. It used to supply Arduino reference voltage.|
|04||GND||This pin is used for ground purposes.|
|05||TX/D1||This pin used for transmission of data.|
|06||RX/D0||This pin is used for receiving data|
|07||AD0||It used for analog to digital conversion.|
|08||IOREF||This pin is used for input, output voltage reference purpose. For example, an Arduino would supply 5 v to this pin, but a due would supply 3.3 v. Sending a signal to this pin does nothing.|
|09||3.3 V||This pin is used for 3.3 v supply to Arduino.|
|10||REST||This pin is used for resting of Arduino.|
|11||VUSB||This is a USB port.|
|12||VIN||At this pin, we supply input voltage to Arduino.|
|13||AO/DAC||This is used for analog to digital conversion of the signal.|
|14||GND||This is two ground in Arduino Zero, this one is second|
|15||PROGRAMMING PORT||This pin is used for the feeding of programming to Arduino.|
|16||SUPPLY CONNECTOR||This pin is used for 2.1 mm supply connector.|
|17||MCU||This pin is used to interface other microcontrollers with Arduino.|

Zero DriveLets discuss project of Arduino Zero.
- Zero Driver is basically an Arduino Zero compatible dual motor driver board for mechatronics engineering projects and different types of industrial robots.
- In robotic projects required two board, one is a microcontroller and other is a separate driver for a motor. Zero Driver combines both in one for our convenience.
- Zero drivers come with the same microcontroller as an Arduino Zero 48 MHZ ARM cortex M0+ chip, which is better than any other an entry-level Arduino Uno.
- For better understand how this work lets see a picture of zero drive.
