【Arduino ZERO】What are they? + Features and Utility ▷ 2022

The Arduino ZERO board It is intended for those users who run projects they don’t support . This is due to the processing power of the MCU, flash memory, and CPU clock.

Because of this, it is important that you know what the Arduino ZERO are and what these boards are for in electronics. This information can be found in the paragraphs of this article.

In addition, we will show you the main characteristics of the board and the criteria that you must take into account when working with the Arduino ZERO. Take a look at this powerful board.

What are the Arduino Zero and what are these electronic development boards for?

The plate Arduino ZERO is a device that has an electronic bus that includes a Core 32-bit ATMEL Cortex-M0 SAMD21 MCU. It is characterized by having a program debuggingor debug, making it possible for the user not to need any external hardware.

It has all the necessary technology to . It is necessary to clarify that its operation is a little lower than that of other plates, since the voltage it supports is 3.3V. All pins except 4 work with external interrupts of type 0 and 1. On the other hand, the direct current, both input input and output, is 7mA and the CPU clock speed reaches the 48MHz.

Features What are the main features of this Arduino board?

The main features of this Arduino board are:

• It is ideal for working in robotics, automation and technology projects.
• owns a embedded debugger that connects to the hardware of the mcu with which you can program the SAMD21 through an interface SWD. This also allows full access to the microcontroller and work with the program codes to modify them.
• The external power that Arduino ZERO has It is done by means of a center-positive connector or by the GND and VIN pins located in the header of this 2.1 mm connector. This means that there is no USB port to power the board.
• The PWM are 3, 4, 5, 6, 8, 9, 10, 11, 12 and 13; while the analog inputs They’re in A0 to A5. The output voltage is at the DAC, which is channel A0.
• The SPI is located at SS, MOSI, MISO and SCK from the plate
• owns a clock that works 48MHz, so it can tell the real time and calendar.

What should I keep in mind when working with Arduino ZERO boards?

The first thing you should know is that the plate Arduino ZERO works with a voltage of 3.3V, a little lower than the rest of the other boards. For this reason, you must take this restriction into account because you could burn the microprocessor and other components. When and open the monitorthe microcontrollers and the execution of the sketch are not restarted, so you will have to restart the process by means of a button that you will find on the dashboard of the software of Arduino.

Power is not provided via a USB input, which could complicate the project if you want to use the 2.1mm jack for another circuit connection. Finally, You must be careful in the number of processes that you attribute to the project. While it is true that this board is far superior in power to the Arduino UNO and you have a powerful microcontroller, good memory and a 48 MHz clock, you should always be aware of the load you transfer to it.

List of the best projects you can do with Arduino ZERO boards

Learn about the best projects you can carry out with an Arduino ZERO board:

WiFi controlled NeoPixel display

With this project you will be able to create a screen of NeoPixel managed by Wifi. you’re going to need one Arduino ZERO board, a ring with NeoPixel type lights, several leds, a breadboard, a 1000 µF capacitor, a 475 ohm resistor and cables to generate the connections. You will have to do the assembly following the descriptions and specifications of the parts and considering the pins on the board, according to everything we have talked about in this post.

When you have the assembly ready you must enter the following code:

#include #include #define PIN 12 #define NUMPIXELS 10 #define interval 50 #define wifiRetryTimes 0 Adafruit_NeoPixel pixels = Adafruit_NeoPixel( NUMPIXELS , PIN , NEO_GRB + NEO_KHZ800 ); uint32_t red = pixels. color(255, 0, 0); uint32_t blue = pixels. Color( 0 , 0 , 255 ); uint32_t green = pixels. color(0, 255, 0); uint32_t pixelColour ; uint32_t lastColor ; float activeColor = { 255 , 0 , 0 }; IPAddress apIP(192, 168, 0, 150); IPAddress netMsk ( 255 , 255 , 255 , 0 ); IP address gw ( 192 , 168 , 0 , 1 ); dns IP address ( 192 , 168 , 0 , 1 ); string ip ; char APssid = “MKR1000” ; char APpass = “MKR1000” ; char ssid = “YourSSID” ; char pass = “YourPassword” ; int keyIndex = 0 ; int status = WL_IDLE_STATUS ; WiFiServer Server ( 80 ); const char html1 PROGMEM = “
