What Arduino Boards Are Suitable For Beginners

Of the various Arduino board variants, what is suitable for beginners?

Arduino Type Suitable For Beginners - In addition to excellent functionality, supported by qualified software, everything you want can be made.

But for those of you who are still wondering, what arduino is the most suitable for beginners, the answer is Arduino Uno.

What Arduino Boards Are Suitable For Beginners
Arduino Uno is a variant of Arduino which has 14 I/O pins with 32KB of program memory. In addition, this Arduino has the following features:
  • The microcontroller is ATMega328
  • 8-bit architecture
  • CPU speed up to 20 MIPS
  • Total number of Pins 32
  • EEPROM data 1024 bytes
  • Program memory type is Flash
  • Can communicate with UART, SPI and I2C protocol
  • Working voltage 1.8 to 5.5 Volt
For more details, please download the datasheet below.

A brief description:
  • Digital I/O pins are used for all digital needs, besides that there are useful pins for PWM such as pins 3, 5, 6, 9, 10, 11 which are marked with "~" and pins for serial communication, namely pins 0, 1.
  • Analog I/O pins are used for ADC (analog digital converter). In addition to ADC, pins A4 and A5 are also used as pins for I2C communication.
  • ICSP pins are useful pins for SPI communication. With this pin we can also program other types of AVR microcontrollers.
  • Pin Power is useful for electronic equipment resources that you will use. For example a sensor module that requires 5V power. You can use the 5V pin as your sensor power source. VIn is one of the input power pins, meaning if you have a 9 Volt external power source, then you can connect it directly to this pin. This VIn pin is connected to the Regulator IC which will convert the 9Volt voltage to 5Volt and 3.3Volt.
  • Power Jack is a connector for External power source.
  • Resettable Fuse is an electronic fuse that will secure all electronic components in Arduino in the event of a short circuit or overcurrent. The way this Resettable Fuse works is that if the current passing through this fuse exceeds the maximum current limit set, it will disconnect automatically until the Arduino goes out. If the current is low again, this fuse will automatically reconnect.
  • USB port is useful for programming your Arduino from a computer, besides if we don't want to use Jack Power or Vin as a power supply connection, we still use USB to get electrical power. The cable used in the Arduino USB port is a USB 2.0 A/B type cable.
  • The Reset button is used to reset the Arduino system. For example, our arduino suddenly hangs or an error in sensor readings, we can use this button to recover the error and the arduino will run from the beginning.
