UNO R3 - Arduino Docs
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, a USB connection, a power jack, an ICSP header and a reset button.
Getting Started with Arduino UNO R3
A step-by-step guide to get started with the Arduino UNO R3. To use the Arduino UNO R3 board, you will need the Arduino AVR Board Package, which comes pre-installed with the IDE. You will need a version of the Arduino IDE, which you can download from the Arduino Software page.

Arduino UNO SMD 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, a USB connection, a power jack, an ICSP header and a reset button.
Overview of the Arduino UNO Components
On the Arduino Mini and LilyPad Arduino, they are intended for use with an external TTL serial module (e.g. the Mini-USB Adapter). External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
Blink - Arduino Docs
In this case, using a 220-ohm resistor with an Arduino UNO R3 (a 5V board) limits the current to a safe level for both the LED and the Arduino pin. Adjusting the resistor value allows you to control the LED's brightness while ensuring safe operation. For 5V boards you can expect the LED to be visible to a resistor value of up to 1K Ohm.
Power Consumption on Arduino Boards
When creating projects that run on a battery or are power-constrained, taking power consumption into account can be critical. It will among other things help you decide which kind of battery you need to use. In this article, we will demonstrate how you can perform power consumption tests, using a power profiler.

A guide to EEPROM - Arduino Docs
3 天之前 · Learn how to use EEPROM, short for electrically erasable programmable read-only memory, on Arduino boards. The microcontroller on the Arduino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off (like a tiny hard drive).
Arduino UNO R4 WiFi Cheat Sheet
The on board ESP32 module is by default running firmware that handles connectivity for the UNO R4 WiFi. You may need to update this firmware to enable new features, or resolve bugs and other issues. There are a few methods of updating this firmware, and you can find them all detailed in our Help Center article.
Universal Asynchronous Receiver-Transmitter (UART) - Arduino Docs
In this article, you will learn the basics of Universal Asynchronous Receiver-Transmitter (UART), a serial communication protocol that can be used to send data between an Arduino board and other devices.
