Glad it's sorted, so now you can indulge me: you said it's wireless comms between two Arduinoes I think?- yet I see nothing in the code to do with that. Or am I missing something?

t is an R3, the old one was an R2.

Well, then it must have a reset button as shown previous.

Maybe it's not a genuine Arduino?

But you shouldn't need to do anything with the reset anyway.... sure you got the right com port?

Ah ok, I see what you mean, I hadn't spotted that....

But Paul's equation and yours are arithmetically equivalent, I still hold, and should work just the same if they work at all.
4  Using Arduino / Programming Questions / Re: Motor & LED Control Code Issue on: Today at 05:30:32 am

Code:
   if(Time - onTime >= 5000)
would be something my friends could understand without a lot of thought.


That's as may be, but the OP's way is arithmetically equivalent, albeit in a cumbersome way. (Except that the inequality needs an equality option like yours does, just in case it doesn't hit the if in the right (edit.. milli-) second.) edit.... taken that out.... it doesn'yt actually need the =, on second thoughts.

You've opened a nasty can of worms with having two threads with the exact same question.....

Creeping featurism is a term synonymous with bad management.


Exactly..... bad project management, especially; the dreaded scope creep.

I can't find the code I had to do something similar. I found an empty .ino file with a promising name so perhaps I didn't save it.

But iirc, what I did was use a 2-axis joystick with a push button. The code for each axis was just knob, doubled up for two pots. I wrote the servo values to eeprom every time I hit the button. Sorry I can't find the code but that may give you some ideas.....

I'll keep looking!

Search the forum btw, there are threads about this.....

Think, 'something you could market' not "something you built in your basement".

Basements are very uncommon here, but a pal of mine has better machine shop kit in his garage than most pro- shops. He does market stuff he makes in his basement ok garage.... So what the hell does that comment mean?

You might want to re-think his name.....
10  Using Arduino / General Electronics / Re: The important of calibration of oscilloscopes. Or not? on: Today at 02:28:16 am
it requires is that I accept the existence of blind corporate stupidity.

It's neither blind nor stupid. You may understand the workings of a 'scope and know that they are infallible. Your client may have no such arcane knowledge and the only way he can be sure that the service you supply to him is reliable is to see some evidence from an independent authority.

If you work i a company with a ISO9000 label calibration is mandatory, whether needed or not.

I was about to post the same, but I was going to word it like this rather:

If you work in a company with a ISO9000 label calibration is mandatory, unless the instrument is marked "for indication only, uncalibrated" or words to that effect.

Flukeing

I just learned a new verb.  Is that usage common in the biz?   smiley-mr-green

It is now.....
13  Using Arduino / Motors, Mechanics, and Power / Re: Combining ultrasonic sensor with motor on: Today at 01:18:46 am
but that doesn't work well.

What does that actually mean?

You shouldn't power the motor from the Arduino: it's very likely to want too much current.

Have a look here for example.

Edit.....  The combined circuit will look like the attached.

Here you go as a starting point.

Glad it's sorted....

Do those tutorials include the fly-back diode on the motor?
