3 Years after finishing my study of computer science (B.Sc.) my search for a new hobby lead me back to the microcontrollers. There were 2 semester microcontroller programming with embedded assembler in C on a ATMEL development board. But I really hated it.
Now I want to give it a second chance. During the years I found some practical use cases and I have some ideas.
But my first question, after researching for dev boards is: how do I port my application from the development board to a stand-alone unit? Do I have to buy single parts and solder them on a board? Or can I buy ready to use components for a single purpose (e.g. switching a motor time controlled).
edit: there were many nice answers which helped me a lot researching about the topic.
As the question got marked as "put on hold - too broad": I wanted to know if I have to solder cheap units or if there exist cheap ready-to-run components to implement a few small applications without buying a relative expensive dev board for each application. I already isolated 3 candidates to buy. Thanks you all for your answers.
