Dear all.. i program my temperature sensor using AD595..i should check 3 condition of temperature reading.. lets say first between 80 deg - 100, second 100-500deg and the last one for other reading.. in second condition i need to have about another 10 ...

Re: analogRead bringt immer zu hohe Werte

Wenn der Taster schießt, werden 5V auf den z.B. A0 gegeben.
Ich gehe also mit 5V zum Taster und zurück zum analogRead.

Ich nutze analogRead, weil ich die digitalen Io´s für Ausgänge benötige.

how can we convert decimal to binary and output it serially through a pin???
(Is there something wrong with your "?" key?)

Code:
Serial.print (23, BIN);
would seem to me to fit the specification.

I'm sure it's possible to read fro that chip using an Arduino. However, unless you have an oscilloscope, you won't know whether you have the signal timings right.

There are Arduino clones designed for use on flying drones that have integrated accelerometers and gyros. Perhaps one of these would be a good starting point for your project. The parameters you're talking about recording seem to be the best you could ...

G'day Rob,

I remember those Big Boards, what monsters.

Re: C Programming for Arduino / The book

Thanks for the extended answer.

I like these lines :
It is a big book, taking you from te beginning to medium advanced stuff like gLCD, VGA modules use, but also making your Arduino a MIDI responsive synth producing 8bit sounds and reading PCM.

Re: Thought this would be simple

Posted: 28 Dec 2012 12:34 AM PST

I suspect adding a digitalWrite() doesn't break anything... it just shows that the code doesn't work exactly as you expect.

What I would do is:
- get rid of _all_ calls to delay() (and understand the blink without delay example)
- decouple the detectio...

You got me AWOL smiley-wink

Rephrase: One can do quite some float math in the 500 milliseconds a delay(500) takes.

Please modify your post above, select the source code and press the # button above the smileys. IT will tag your code properly so it becomes more readable

Hey guys, I'm new to the forum and also Arduino. I come from a very extensive software background and I'm just starting to dip my feet into hardware development.

Does this particular routine only control 4 servos?
Yes.

Can more servos be added?
Yes, though I'd advise using an array of Servos, rather than individual named instances.
With a regular Arduino, you ought to be able to c...
