Wow this is killing me. Something so simple and it's not working for me.
I have 5 of this sensors I've just got off ebay, they are the red/green/yellow type. Here is a pic of my setup. I previously thought I'd got the wrong resistor, but reading around people are using other pull up resistor sizes with this cable so I should have got something. I've got the correct 4.7k resistors today. Still null.
This is my setup. What am I doing wrong. I'm on v1.69 firmware. Also connected is a cc300o and bluetooth module. I've powered down the cc3000 but it makes no difference. I'm using A0 for the data. Tested on A1 too. Same result.
Either I'm missing something basic, somethings not working on my board or I've been sent 5 duff sensors (tested with 3 so far, 2 different breadboards, and I've bridged an LED to confirm I've got 3.3v coming out)
Apologies for posting up on something so basic, but I can't see where I'm going wrong.
