The audio component centers around the SS8550 PNP transistor (Q1) which serves as a driver for the passive buzzer (BZ1). This ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

Though the I2C bus can run for years without issues, sensors often “lock up” in practice, blocking all communication. A transistor circuit solves this.

Board ESP32-S3 custom board Device Description Not relevant, same HW works perfectly on 2.X.X Hardware Configuration #define I2C_SCL 42 #define I2C_SDA 41 Version latest stable Release (if not list ...

The purpose of this paper is to design and simulate a Protocol Conversion Unit (PCU) for seamless communication between the two widely accepted serial communication protocols SPI and I2C. Design given ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

What made the I2C bus such an overwhelmingly popular embedded connectivity technology for nearly four decades? And how is the I3C bus carrying its legacy forward?

Arduino is a hobby that not only teaches you about programming, automation, and robotics, but also yields useful devices that can help in everyday life.
