Let’s do something crazy: Let’s combine an Arduino Pro Mini (or compatible) with a BMP180 air pressure and an SD card module, and explore long-term infrasound level recording.

The Pro Mini combines an Arduino Pro Mini with a host of inputs and outputs to allow users to experiment with the Arduino language.

So he tried his hand with some really small SMD parts by building this USB to serial Arduino programmer. The chip he went with isn’t the FTDI part we’re used to.

When they have mastered programming the ProtoSnap Pro Mini, it can be broken apart so the individual components can be used separately.
