Why project is important ?
The art of electronics is the art of transforming a thought or idea in to concrete reality by designing and making it. Building on the knowledge, experience, and work of others makes transforming that idea to a real electronics project easier. However, while electronic project will be unique, they all follow the same sequence to transition from thought to reality.
Any electronics project starts with the decision of what to build. The more formed the idea is, the easier it will be to tackle. Of course all designs shift along the way as the idea intersects with reality, what can be done, and what building blocks are available. Developing that solid idea of what you want the project to do, look like, how people will interact or control it, and how it will be used allows you to find other projects with similar elements that can be used for inspiration on the design and construction of your own project.
