Arduino & Android

Hi,

I have an Arduino Esplora and an Android 4.x phone. I purchased the necessary USB micro B (male) to USB type A (female) cable and wired the phone to the Arduino, but the Arduino doesn't light up. How to power an Arduino off an Android phone?

My goal is to have the Arduino send messages to the phone.

Thanks

As far as I know most phones don't provide power out unless you connect directly to the battery and I would not recommend that.

Thanks for the reply. So...Does that mean I can't connect an Esplora to the phone? The USB is the only way an Esplora can be powered, right? Thanks

You might try asking over on the Arduino site.

Yes the USB on the Esplora draws a number of milliamps and phones typically do not put out power over USB or if they do the Esplora would quickly run down your battery. It's really designed for hooking up to a PC/Mac/Linux.

There are some hacks to run Esplora off battery power. I did it with some Adafruit parts. With some ingenuity you could have the Esplora hooked to Bluetooth to talk to the phone.
