it looks like a fun and quick project that’s more than suited for hobbyist measurements. It’s not only easy to build, the Arduino sketch is less than thirty lines of code. This is a great ...

[Martin] sent in a great guide to a simple Arduino based theremin. It’s a very small build – just a single common IC and some passive components – and easy enough to build in an afternoon.

But if you’re just starting out, here’s a quick list of ... equipment is fairly easy to work with, and with enough practice, you’ll be hardwiring your Arduino projects in no time!

The BLE shield board complies to the Arduino form factor and contains all necessary circuitry to enable an Arduino project to start communicating with Bluetooth Smart Ready products such as an iPhone ...
