Created page with "Sometimes you will not find an Arduino board that fits the needs of your projects and you might want to use a different Atmel microcontroller. In this section we will explain..."

New page

Sometimes you will not find an Arduino board that fits the needs of your projects and you might want to use a different Atmel microcontroller. In this section we will explain how to integrate your custom board into the Arduino IDE so that you can use it to program it.
