Arduino... Arduino is open-source. Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its hardware products are licensed under a CC-BY-SA license, while software is licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the ... There are so many different varieties that it is almost impossible but certainly superfluous to discuss them all, so I will stick to the four I use the most so far. View Arduino Mega. View Arduino Nano. View 3D Arduino Pro Mini. View 3D Arduino Uno. ./2020. Arduino Mega Arduino Mega. a microcontroller board based on the ATmega2560. It 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; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila. ./2020. Arduino Nano Arduino Nano. The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P. It offers the same connectivity and specs of the Arduino Uno board in a smaller form factor. The Arduino Nano is programmed using the Arduino Software integrated development environment (IDE), which is common to all Arduino boards and running both online and offline. Control a car with BlueTooth.. Make a toy car run on Bluetooth and an Arduino Nano and controll it with an app on a mobil. ENC28J60 on a Nano (ATmega328P) as webserver. Make a very simple webserver with an ENC28J60 and an Arduino Nano with four switches and relais. ./2020. Arduino Pro Mini Arduino Pro Mini. As its name would imply the Pro Mini is a very tiny device, it’s not much bigger than the DIP version of the ATMega328 chip. The Pro Mini uses a surface-mount ATMega328, giving it the full power of the Arduino Uno in a much smaller package. Another way that the Pro Mini outshines its bigger brother is that it is available in both a 5-volt and 3.3-volt model. This opens up the possibility of creating battery powered projects, or directly interfacing with 3.3-volt logic devices. The 3.3-volt Pro Mini runs at a slower clock speed, 8 MHz. For most applications, this will not be an issue. But for all its extra versatility the Pro Mini has one feature lacking – it has no USB port. AC/DC current and DC voltage sensor. Make a AC/DC current and DC voltage sensor on an Arduino Pro Mini with an OLED display. ./2020. Arduino Uno Arduino Uno. Arduino Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. Develop Barribot. Barribot, barricade avoidance robot, is a fun project with many development options that started on an Uno.
