The system consists of an Arduino board integrated with an HC-05 Bluetooth module and an LED. Using a custom Android application, the user can manipulate the LED's state (On/Off).

Here we are basically Interfacing Bluetooth Module with Arduino. Through Bluetooth Module we are going connect Android phone to Arduino through an Android application. Remember to disconnect pin no 0 ...

Fig. 2: Author’s prototype of Arduino based programmable digital data display In this application, the Bluetooth module acts as both transmitter and receiver, and is compatible with most smartphones.

Lauterbach extends the range of Arduino supported boards and devices. After the successful integration of the »Pro Portenta H7«, Trace32 now also supports the Arduino »Nano 33 BLE« and »Nano 33 BLE ...

To deal with this you’ll want to supply the Arduino 5V via the RAW pin (it’s regulator will then supply 3.3V to VCC feeding the Host Shield and Bluetooth module).

With that backdrop, Arduino LLC has now introduced Arduino 101 (aka Genuino 101) board powered by Intel Curie module with Quark SE x86 SoC with Bluetooth LE and a 6-axis combo sensor.

Today, Coin announced that it will offer up an Arduino Bluetooth Low Energy module that’s designed to be small and easy to integrate into hardware hacks and products of all kinds.
