Powering JY-MCU HC06 Bluetooth adapter from the digital pin of an Arduino ??

neilk
neilk over 10 years ago

I'm doing a lot of experiments with Arduino, Android and a JY-MCU HC06 Bluetooth adapter.


I'm becoming increasingly frustrated by the frequent need to reset the HC06, before it will accept a connection from the Android device. The easiest way to reset the HC06 is to briefly disconnect the +5V supply.

 

According to a spec of the HC06, which I found via Google, the HC06 draws 20-30mA when pairing up and 8mA in normal use. Since an Arduino Uno digital pin can supply 40 mA, wondered if I could power the HC06 from a digital pin, allowing me to reset the HC06 via software control of the digital pin.

 

Please can anyone offer any help or advice in this area?

 

Many thanks


Neil

    Hi Clem Here is a photo of the Bluetooth adapter: At the moment, VCC isconnected +5 on the Arduino, and GND is connected to GND on the Arduino. I realise I could just put a switch in the +5 connection…

    Substitute the relay coil connections with the Bluetooth module.

    You could put a transistor between the arduino and the Bluetooth module just to be sure.

    Hi Paul

     

    Understand how to use a transistor to, say, drive a relay from an Arduino pin; don't quite understand how to use on for this application?

    Thanks Paul, imagined it would be a bit more complicated than that image
