At the heart of nearly every Arduino project are three core functions: digitalWrite() digitalRead() analogRead() Arduino interacts with the real world by turning pins on and off, reading button states, and measuring sensor values. Even though they seem simple, it’s …

Flash, SRAM, and EEPROM are the three different types of memory that Arduino boards use. Each type has its own job. To write stable, efficient, and scalable sketches, you need to know how these types of memory work and how …

Arduino’s UNO Q is a dual-brain board that blends a Linux-capable Qualcomm Dragonwing QRB2210 application processor with a real-time STM32U585 microcontroller—in the familiar UNO footprint. It ships with Arduino App Lab pre-installed, supports Wi-Fi 5 / Bluetooth 5.1, has 16 …

Qualcomm announced it will acquire Arduino, the open-source hardware and software platform with a community of more than 33 million developers. Terms were not disclosed. Arduino will retain its brand, tools, and open-source mission while continuing to support chips from …

The Arduino Serial Plotter is a built-in tool in the Arduino IDE that allows you to visualize live data from your Arduino board in real time. This is particularly useful when working with sensors, analog readings, or debugging data. Unlike …

EEPROM (Electrically Erasable Programmable Read-Only Memory) allows you to store data permanently on an Arduino, even when power is lost. This is useful for storing settings, calibration values, or user preferences. Basics of Using EEPROM in Arduino The EEPROM on …

In this article we look at a temperature and pressure sensor, the STS35 temperature sensor from Sensirion, and connect it to an Arduino R4, you can use an older Arduino Uno. It will work just fine. Sensor Information The STS3x-DIS …
