Question to perimeter receiver / sender

[alda]

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 ) ?

Thanks

No answers to wiring diagram ? and is this solution for perimeter sender still actual one or is there any other solution ? :

hi
I got a question
where is correct circuit?

main.jpg or receiver.jpg

one circuit without condensator + resistor, but on perimeter circuit condensator 100n + resistor 200k are exist.

what is right outputs D10 and D11 or A4 and A5 ?

A0 A1 from coils to NANO
and A4 A5 output to MEGA from NANO

ok

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.

Dear All,
about perimeter receiver...
Is it correct the connection of the attached file?

I by-passed also the C3 condenser..

Can I proceide?

thank you

Dear All,
I did this connection of LM386, perimeter receiver...is this correct?
I'm not sure..

Please indicate me the right connections..

Thank you
BYe

I wrote allready it looks good.

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

ALEX...Do you use centered coil ....with two coils + 2 capacitors? Like the pictures?

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.
