If you are willing to spend some money development boards are a quick way to get started. They typically have a microcontroller, voltage regulator, some LEDs, and some sensors all on one board. The downside is that if you break anything on the board you have to buy a whole new board. With discrete components only the broken part needs to be replaced. On the other hand, more and more components are only available in surface mount packages which almost require a custom PCB to use at all. ARM processors are relatively powerful microcontroller but at present are not available in through hole versions. | If you are willing to spend some money development boards are a quick way to get started.
