Introduction to Node MCU as a brain of Internet of Things

This document discusses Arduino and its history and applications. It notes that Arduino was created in 2005 as an educational open-source hardware project. It was developed by Massimo Banzi and others to provide a low-cost, easy-to-use platform for prototyping that could be used in classrooms. Arduino was built upon Wiring, an earlier open-source electronics platform, to make hardware programming more approachable. It has since grown into a large community and product line used widely for hardware prototyping, especially in IoT and home automation applications.

The role of wall art in interior designingmeghaark2110

Wall art and wall patterns are not merely decorative elements, but powerful tools in shaping the identity, mood, and functionality of interior spaces. They serve as visual expressions of personality, culture, and creativity, transforming blank and lifeless walls into vibrant storytelling surfaces. Wall art, whether abstract, realistic, or symbolic, adds emotional depth and aesthetic richness to a room, while wall patterns contribute to structure, rhythm, and continuity in design. Together, they enhance the visual experience, making spaces feel more complete, welcoming, and engaging. In modern interior design, the thoughtful integration of wall art and patterns plays a crucial role in creating environments that are not only beautiful but also meaningful and memorable. As lifestyles evolve, so too does the art of wall decor—encouraging innovation, sustainability, and personalized expression within our living and working spaces.
