Working with multiple sensors on an Arduino can unlock richer, more interactive projects. By integrating motion, light, distance, and environmental readings, you can create systems that respond ...

[Jacob Geigle] had a problem. A GPS unit and a Bluetooth-to-serial were tying up all the hardware UARTs on an AVR Arduino project. “Software serial”, I hear you say. But what if I told you [Jacob] ...

So let’s say your using an Arduino in your project. You already have the hardware-based serial interface working with one portion of the project and need a second serial port for unrelated hardware.
