TechBitar shared his latest project the BridgeDuino with boards from DirtyPCBs:

BridgeDuino is a Swiss army knife PCB for rapid networking of inexpensive wireless communication modules. Breadboards are super for one-off experiments. But after prototyping half a dozen wireless prototypes involving more than just two Arduinos, the wiring mistakes and associated debugging grew more time consuming.
I also wanted a PCB that can act as a shield to Arduino Uno as well as work with the inexpensive and low-power Arduino ProMini.

As of this release, BridgeDuino supports the following wireless technologies/modules:
IR Transmiter LED 940nm
IR Receive 38Khz
RF433Mhz Receiver
RF433Mhz FS1000A Transmitter
Bluetooth HC-06 & HC-05
Nrf24L01+

Automatic Bluetooth Module Programmer

Before we dive in don’t be confused by the title. This doesn’t flash firmware to the device. But it does automate the process of setting up the Bluetooth to serial module for use in your projects.

We’re often confused by the lack of a standard way of describing these inexpensive modules. We would look at this can call it an HC-05, but we’re not sure if that’s right or not. [James Daniel] calls it a JY-MCU board. If you have a handle on the differences (or lack of) please let us know in the comments. Either way we know that these boards can be frustrating to work with. They can be found with a wide variety of different firmwares, which can make the configuration process a bit different for each.

[James'] solution connects the device to an Arduino running a sketch that he wrote. Connect the device, launch the terminal monitor in the Arduino IDE, then give it your desired settings. The sketch will poll the Bluetooth module to see what speed it is set to run at. It will then establish which firmware version the board is running, displaying this info in the terminal. It then uses that information to program the board with your desired settings.

In this case [James] is using one of the modules to drive his 3D printer without being tethered to his laptop.

Two-way Bluetooth communication made easy

two-way-bluetooth-with-Android

It’s hard to imagine an easier way to set up communications between an Android device and an Arduino using Bluetooth than by following this guide. In the center of the breadboard you can see the cheap and ubiquitous HC-05 Bluetooth module. Having picked up one of these ourselves we can attest that after opening the package and holding one in your hand you may be struck with a “where do I start?” conundrum. If you’ve got an Android handset and anĀ Arduino you start right here, then methodically replace one side of the equation at a time until your own project has a Bluetooth component and you actually understand how it works.

Hardware for the project comes in a couple of parts. 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. The software end of things consists of an Arduino sketch and an Android app. Check out all the controls on that screen. With bi-directional communications and a slew of already-configured commands this should get you up and running quickly on pretty much any possible project.

One thing to note is that there are different firmwares for these HC-05 units. For more on that see this project.
