Doing Micro controller project is to expensive. A simple LED breakout board can cost a lot for hobbyist or for student if it is ordered online but if you have lots of junk PCB board with LED you can make your own LED breakout board. A single LED is easy to build, what if , if you want to build your own seven segment display breakout board, by the way Seven segment display is made of LED's, the solution is dig your junk , find scrap that is suited to your project. Here I found the old Communication Port, I pull out the pin headers, to be used as header pin for seven segment display breakout board. The seven segment is already in my box, I know I can use it in the future's project so I kept it before. The procedure! you can see it in the picture below. Later I'll update this for circuit connection.
