In this tutorial we will see how to connect the RGB LED with ARIES IoT v2.0 <\/strong>Board. The RGB LED can emit different colors by mixing the 3 basic colors red, green and blue.<\/p>\n\n\n\n

Aries IoT v2.0 Board<\/h2>\n\n\n\n

The ARIES IoT is a fully indigenous and a \u201cMade in India\u201d product to get started with basic microprocessor programming and embedded systems. This board is built upon a RISC-V ISA compliant VEGA Processor with easy-to-use hardware and software. For more details about ARIES IoT boards please refer to the ARIES development boards and Ecosystem.<\/a><\/p>\n\n\n\n

RGB LED<\/h2>\n\n\n\n

The VEGA ARIES IoT Board features an onboard RGB LED that can emit Red, Green, and Blue colors individually or in combination to produce multiple color outputs. The RGB LED is connected directly to the microcontroller, allowing users to control each color channel through software without any external wiring. It is useful for status indication, notifications, debugging, and learning PWM-based color mixing in embedded and IoT applications. On the ARIES IoT Board, the RGB LED pins are Red (GPIO24), Green (GPIO22), and Blue (GPIO23), and the LEDs are active-low, meaning a LOW signal turns the corresponding LED ON.<\/p>\n\n\n\n
