I recently wanted some breadboard setups for students ... boilerplate examples you can use in a new project. The code is simple. Just like the Arduino has a lot of helper library routines ...

Apart from understanding the Arduino's code language ... prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered. If your project calls for female ...

This is quite an old project, and we’ve actually seen a successor to it. This is Rev. 2 and we looked in on Rev. 7 back in March. That one is a full Arduino, but the circuit board has no substrate.
