Thanks.

Sure, what do I need to do? do I need to upload it to some where?

Hi.

I just wanted to share the project I have finished some time ago:

What you all think?

Well, toke some thing like a week, but the machine is ready, the Hzometer! mamama!   and ya the highest frequency tone() can come to is 60KHz... It is good to know that ppl here know what they are talking about.  

Not all frequencies are illegal and it depend on how you transmit them... some yard a way for an experiment will not let you talk to some rushen submarine comerat commander...

But you do say that you think I can get to 1Mhz... how? can I just write tone(pin, 1000000) that will not work, right?

Yes using radio signal just like that is "wrong" :. But I am not getting to the frequency that is illegal.... And maybe I am from Alaska... where every thing is free...  

I was thinking to use it to make some weak, easy to control, radio signal.

If I use the pin HIGH, delay, pin LOW, delay.

I get a problem, that what ever I write on the program will change the signal, that why I was thinking about using tone()

What do you think?  :-?

Thanks, and sorry Grumpy Mike...

Can one do what you just said, modified tone()?

Opss... that the "t" is MISSING!!!!

Sorry dude... having a bad day or some thing?

Maybe we can just start a witch hunt...

So it is coz of the int the is in the tone(), witch define the Hz, that can go over 60000...

Ok thanks.

Are you sure about it?

the Arduino clock is much faster and it you can get higher frequency only buy writing HIGH, delaymicro, LOW, delay...

I tried it yesterday with X as frequency and a analogRead to control the X.

I gut up to over 100000Hz.

Then I tried 20Mhz, I wrote 20000000, witch is the Arduin Duemilanove clock.

It worked, but I am not sure at witch frequency...

The way I chekt it was plugging the output to antenna and trying to read volt that is crated on a diode witch is grounded from one side and connected to other antenna on the other side

Are you sure in what you are saying? , Or did I do some thing wrong?

No buddy knows?

Hi.

Simple Q

What is the highest Hz the Arduino can give with the tone() function?

Thanks.

Thanks, it worked fine when I define it a positive long.

Hi.

When I do X = millis();

X is going up to some thing like 32000 and then to 0 agian...

Can I tell millis() to go to 0 befor? like after 20000 millisec?

I have the PIC12F508-i/p chip

What do I need to get? is there some good guide?
