Microcontroller-based projects are projects – oftentimes undertaken as hobbies – that utilize microcontrollers to perform some sort of a complex function. In an educational or hobby sense, they provide a way to demonstrate the tremendous power of the microcontroller and how it can take the place of many different pieces of equipment.
Microcontroller-based projects are generally packaged with everything that the user needs to put together a specific type of system that utilizes a microcontroller as one of its primary components. They will contain the board on which the various components need to be installed and, in some cases, those components will be preinstalled to eliminate the need for soldering. Some of the devices actually come with inputs and outputs already set up on the board, allowing the user to, essentially, get a highly configurable and customizable bare-bones version of very advanced technologies that they can utilize.
Microcontroller-based projects are generally very flexible, as well. For example, some of them have the capacity to work with a specific type of technology – i.e., video – but can do so in several different ways. They may be able to receive video input from various sources, process it and take specific actions based on that video but they may be able to work with other types of sensors, as well.
Microcontroller-based projects are sometimes utilized as ways to experiment with new ideas for microcontroller based products, as well.
