Sending Sensor Data via Bluetooth

Introduction

Is there anything more tedious than having to connect dozens of wires to get your latest project up and running? Wouldn’t it be nice if there was some way to wirelessly send data over short distances and eliminate the need for all those pesky wires? Enter Bluetooth!
