This project focuses on developing a system that allows the control of an LED using an Android app via Bluetooth. The system consists of an Arduino board integrated with an HC-05 Bluetooth module and ...

Whether controlling an LED or an AC device, this setup demonstrates a simple yet powerful application of Arduino and Bluetooth technology. The author’s prototype is shown in Fig. 1. The list of ...

As a perfect example, these LED “blinking eyes” were created by [Will Moser]. Using nothing more exotic than some bare LEDs, an Arduino, and a cardboard box, ...

The Bluetooth module wants 3.3v logic levels so that is taken into account. The image above shows a buffer chip doing the conversion, but the Fritzing schematic on the post uses a voltage divider.

You know, we don't see too many didgeridoos in these parts (and for good reason, seeing as how it is little more than a pipe) but wait'll to you get a load of this aerophone-wielding maniac: Kyle ...
