I was thinking to build a very small USB Audio Streaming device with aux output for an amp (I know they already exist, but I like the self invention). So I bought an Arduino Nano and a USB Bluetooth device with was originally for a computer. But I thought I might use it on the Arduino. After I removed the housing and soldered four wires onto the USB plug:
I needed to know how to wire them:
So I connected:
- "1" to 5V+ on arduino
- "2" and "3" need to be connected to txd and rxd on the arduino (but I don't know whitch way around)... I read that I need to have 3.3v on "3" or the "+" wire but I have 5V Output on the digital Pins on the arduino (so I need some resistors, but I'm not familiar with calculating them).
- "4" to gnd
Can someone confirm and / or provide some information for me to get this thing running (Bluetooth device enabled and functioning)?
Further steps would be:
- coding the arduino to Use the Bluetooth module for audio streaming - preferrably three Channel.
- configure the arduino to give the stream to an amp.
I know my knowledge of electronics is not very good and I need some education. If you can provide some good learning websites - feel free to suggest.
