We can select the 3.3V or 5V versions of the Arduino board. So, we will select the Processor as ATmega328p.Ĭlick on 'Tools' and select Processor, as shown below: The ATmega328p microcontroller is used in the Arduino Pro Mini.
Arduino pro mini software serial code#
Open the code or sketch written in the Arduino software. The steps to get started with Arduino Pro Mini are listed below: We can also use Arduino Web Editor, which allows us to upload sketches and write the code from our web browser (Google Chrome recommended) to any Arduino Board. We can program the Arduino Pro Mini using the Arduino IDE. Arduino pro mini software serial how to#
How to get started with Arduino Pro Mini? The PIN from 2 to 13 are the digital I/O pins. The above 8 analog pins are used as the analog inputs in the Arduino Pro Mini board. The resolution of the analog pins is 10 bits. The Vin is the input voltage pin, which is applied while using the external power source.Ī0, A1, A2, A3, A4, A5, A6, and A7 are the analog pins. We can also regulate the voltage of 5V depending on the versions of the board.
It is used to add a Reset button to the connection. RX1 is the communication pin, which is used for receiving the data. The Tx0 pin is used for transmission of the data. These two pins can also be used as the digital I/O pins.

Tx0 and RX1 pins are used for serial communication. There are three GND (Ground) pins present on the Pro Mini board. The Pinout of Arduino Pro Mini is shown in the below image:
The input voltage varies from 5V to 12V. There are 14 digital I/O pins, which comprise of 6 PWM (Pulse Width Modulation) pins. The LED will blink only when we will run the program. The crystal oscillator present in Arduino Nano comes with a frequency of 8 MHz. The technical specifications of Arduino Pro Mini are listed below: Technical Specifications of Arduino Pro Mini The preinstalled flash has a bootloader, which takes the memory of 0.5 Kb. The Memory structure of the Pro Mini is similar to Arduino UNO. The USB port is absent on the Pro Mini board, while Arduino Nano consists of a mini USB port on the board. The size of the Nano board is slightly larger than the Pro Mini board. The differences between Arduino Nano and Pro mini are listed below: What is the main difference between Arduino Nano and Arduino Pro Mini? The Arduino Pro Mini includes 8 analog pins, 14 digital Input/Output pins from which 6 are PWM pins. The Arduino UNO includes 6 analog pin inputs, 14 digital pins, a USB connector, a power jack, and an ICSP (In-Circuit Serial Programming) header. The size of the Arduino Pro Mini is very small compared to the Arduino UNO. The oscillator frequency of Arduino Pro Mini is 8MHz, while the oscillator frequency of Arduino UNO is 16MHz. Arduino Pro Mini operates at the voltage of 3.3V, while Arduino UNO operates at the voltage of both 3.3 and 5V. The differences between Arduino UNO and Pro Mini are listed below: We need to solder the headers while implementing the board in our projects.ĭrawback: The Built-in programmer, shield, and USB port are absent in Arduino Pro Mini.Īrduino Pro Mini board is shown below: What are the differences between Arduino UNO and Arduino Pro Mini? Here, IDE stands for Integrated Development Environment. The Arduino Pro Mini is organized using the Arduino (IDE), which can run on various platforms. It is primarily used in compact size projects due to its small size. For 5V, we are required to use the Arduino Pro Mini 5V board. 
If we want to use the operating voltage of 3.3V, we need to use the Arduino Pro Mini 3.3V board. It is preferred by advanced users for greater flexibility and small size. The connectivity and functionality are the same as other Arduino boards. The Arduino Pro mini is a small Arduino board based on ATmega328P or Microcontroller.
