Hi,

As the subject says: I need 6 analog input for a project.
Anyone have a good tutorial how to accomplish this?
I read this post http://www.esp8266.com/viewtopic.php?f=13&t=4451&hilit=analog+extender#p25543
and it seems like I can use MCP3004, MCP3008, MCP3021, MCP3421 for this, but I need someone to tell me how to do this.

The first thing I would do is to look for a library for one of the parts. After that it would depend on what exactly you found. Or you can make your own routines by looking at what someone else has done.

Thats just it rudy, I'm not an expert on this, I'm quite a novice.
Thats why I need someone to tell me what to do.

Maybe this is the best way to go?

Since you need 6 inputs, I would choose AD5593R.
If you wish a rather cheaper solution, you can still use the ESP ADC single input and add a CD4051 analog multiplexer controlled by 3 GPIOs to select the inputs.
