RGB LEDs, or Red-Green-Blue Light-Emitting Diodes, are a type of light-emitting diode that can produce a wide range of colors by combining different intensities of red, green, and blue light. In this article, we’ll explore the RGB LEDs, their functionality, and how to interface them with Arduino to create captivating lighting effects and colourful projects.
Master-Slave communication between two Arduino boards involves establishing a communication link where one Arduino, designated as the master, controls and communicates with another Arduino, the slave. This communication is typically achieved through a serial communication protocol like I2C or UART. The master Arduino initiates the communication by sending commands or data to the slave Arduino, which responds accordingly. This method of communication can be employed in various applications, such as robotics, home automation, and sensor networks, facilitating efficient and organized collaboration between different components within a system.
