Question to perimeter receiver / sender

Hi,
one question to perimeter receiver. In wiring diagram (schaltbild) I found, that signal from coils is going to ADC1 and ADC0 of Arduino Nano and from Nano is output pin A4(SDA) and A5(SCL).

But in menu "Induktionsschleife / IR-Baken " on the picture is signal from coils connected to A1 and A0 of Arduino Nano and from Nano is output pin D10 and D11.

What is right connection ?

Thanks

Alex
 
and one additional question :
If I want use 4 coils, can I connect coils parallel + capacitor serial ( see Picture ) ?

Hi Sven,

thank you, regarding parallel coil connection for signal detection - is my theory right, that I can use 4 coils ( 2x2 ) but I must recalculate capactior to get 7,8khz ? Information about practise with more coils I have seen somewhere on the forum, but now I can't find it. Anyway my plan is test it in the praxis.

Thank you StefanM,
now that I see your picture linked I understand that my circuit is wrong...I connected the OUT to the coil, instead of IN.

thank you

bye
 
Hi fabio,

Now I'm reworking my perimetr wire system to SVN version with different SVN sender and only one coil and amplifier.
When all is done, I will share all informations in my project thread.
