Arduino is a type of source which is available to the entire user as it is open source and this type of compiler is totally based on interfacing of hardware and software. Arduino boards like Arduino Nano, Arduino MKR and many other boards which are available can easily read input from the commands which can also turn on the sensor, finger button, or other notifications and this leads to the output which activates the device by turning on the LED, and publish something online using a server. This type of board works by sending a set of commands to it. To give the commands we generally use the programming language preferred by the board as well as Arduino Software. Arduino Uno is generally connected by a universal serial bus connection or through the employment of an external power source. The external source of power supply can be taken from an adapter AC to DC or by deployment of a battery. This adapter is connected through a 2.2 mm size plug to the on board power supply. The board can survive up to 6 to 20 volts as an external supply. If given below 7 volts, as we know the 5 volts pin can provide not more than five volts supply and on the same time the board can become unstable. If we exceed more than 12 volt supply the voltage regulator will get heated and may damage the board. Preferable range for supply varies from 7 to 12 volts.

Power: Arduino UNO board can be powered by external power supply using USB connection (Figure 9.2). It works on 5 V DC power supply, so board can be either connected with laptop through USB cable, or adapter can be used which converts AC into DC power supply. Board can also operate on 6–20 V power supply. Some of the power supply pins used on board are explained below: Vin: If board is powered through external power source, this pin can be used. Supply can be given through this pin or can be accessed also when power is given by USB port.5 V: Power supply on this pin is regulated by 5 V DC power supply that is obtained from onboard regulator. Input power to voltage regulator is supplied through DC power jack or USB connector.GND (Ground): This pin can be used to make GND connections.IOREF: The main use of this pin is to supply reference voltage. This pin mainly works with 3.3 V DC power supply.

The design of this system was tested on the Arduino UNO R3, with this tool expected to facilitate daily activities, especially in terms of managing door locks and home lighting. Arduino UNO is an ATmega328-based microcontroller board with 14 digital input–output (I/O) pins (where 6 pins can be used as output PWM), 6 analog inputs, a clock speed of 16 MHz, a Universal Serial Bus (USB) connection, a power jack, a header ICSP, and a reset button. The board uses power connected to a computer with a USB cable or external power with an AC-DC adapter or battery (Syahwil, 2013). Arduino UNO has specifications such as the Arduino UNO board, an ATmega328 microcontroller, 5V operating voltage, 7V–12V input voltage, 6V–20V input voltage limit, 14 I/O digital pins (6 output pins PWM), 6 analog input pins, 40mA DC current per I/O pin, DC current for 3.3V 50mA pin, flash 32 KB memory (ATmega328), where 0.5 KB is used by a bootloader, 2 KB SRAM (ATmega328), 1 KB EEPROM (ATmega328), and a 16 MHz clock.

In this section, we will perform an experimental validation of the comparative study of MPPT fuzzy controller types using an Arduino Uno board. As depicted in Figure 18, the hardware part consists of a buck converter, a PV panel of a current sensor, a voltage sensor, an Arduino Uno, and a lead-acid rechargeable battery as a load. A current sensor (ACS712-5) is used to sense current. A potentiometer is used as a voltage sensor to measure the voltage of PV. The Arduino UNO is a microcontroller board based on the ATmega328P. A buck converter circuit is used to convert PV voltage to load voltage. The buck converter consists of an input capacitor, a MOSFET driver circuit to safely drive the turning on and off of the MOSFET IRFZ44N, an inductor, a MOSFET transistor, a diode, and an input and output capacitor. The PV module located on the roof was used to evaluate the performance of the MPPT fuzzy controller types under real environmental conditions, using a 45° inclination angle for it. Before the tests, the battery had been fully discharged.

Published in Instrumentation Science & Technology, 2023
Arduino UNO is a microcontroller board based on the ATmega328p. Due to its robust design, it is one of the most used options to begin in electronics and coding. The Arduino board has 14 digital input/output pins, 6 analog inputs, and a USB connection. Of the 14 digital pins, 6 may be used as the pulse width modulation (PWM) output. The board also has a 5 V and 3.3 V voltage supply for low current applications.
