Dear Sir.
I saw the circuit diagram of the Geiger counter in the attached PDF, but there is no information about the used transistors... I did not found the BF546 datasheet. Is it wright ? And the other 2 to drive the speaker?
About the secondary of the transformer: How much turns did you used?
Thank you very much, Mauricio Girardi.

Dear Sir,
I am relatively new to Arduino and C programming. Can you please tell me if is the counter reset by program or manually?
Thank you for potential answer.

Dear Jani_Slegr,
thank you for interest about Geiger conuter.
In the program I wrote the counter is just counting pulses and the number is increasing. This large number is read out by computer once a minute via USB-serial Arduino interface. Pulses per minute are calculated on the computer. Computer just compares the current value with the value that was one minute ago.
Wish you a Happy New Year!
