Rather than requiring a physical press of the reset button before an upload, the Arduino/Genuino Uno board is designed in a way that allows it to be reset by the software running on a connected computer. One of the hardware flow control lines (DTR) of the ATmega8U2/16U2 is connected to the reset line of the ATmega328 via a 100 nanofarad capacitor.
The default bootloader of the Arduino Uno is the Optiboot bootloader. [33] Boards are loaded with program code via a serial connection to another computer. Some serial Arduino boards contain a level shifter circuit to convert between RS-232 logic levels and transistor–transistor logic level signals.

The STK600 allows in-system programming from the PC via USB, leaving the RS-232 port available for the target microcontroller. A 4 pin header on the STK600 labeled 'RS-232 spare' can connect any TTL level USART port on the chip to an onboard MAX232 chip to translate the signals to RS-232 levels. The RS-232 signals are connected to the RX, TX ...
Tinkercad's Circuits section is a browser-based electronic circuit simulator that supports Arduino Uno microcontrollers, Micro:bit boards, or ATtiny chips. Code can be created using graphical CodeBlocks, [13] pieces of code that can be easily arranged with the mouse, or text-based code.

The Arduino Nano is an open-source breadboard-friendly microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2008. It offers the same connectivity and specs of the Arduino Uno board in a smaller form factor. [1]
