Hi all

Do libraries as like exemple.h and exemple.cpp make arduino restart faster???

ok, was what i was thinking...
meanwhile, i tested the board and the output it seams to be the one i expected, let see tomorrow with other parts,

what is the difference betewen "pulldowns" resistors and "gate resistor" ??????

Thank You!

Hi fungus, Thank You! for reply,

To understand, where should be connect resistor?

I really hope whatever you put on there begins with "IRL", not "IRF"...

is nor IRF  smiley-roll-sweat

Where will you connect the Arduino GND? It would be nice to have a proper terminal for that.

I´ll use, an extra transformer like


with 5V to arduino and 12V for this part, is ok right?

i think gate resistor are those 3 resistors to each IRF right?

nice idea to separate GND, is to run 12v maximum...

Thank you

HI

i´m trying to burn some power control like sparkfun power driver on EAGLE,

  


I ended like this board, it seams everything ok???





i´m alredy printing on board, but i haven´t been sucessefull...

any tricks??
PEACE

7  Using Arduino / Project Guidance / PinChangeInt.h QUEST AFTER 1 HOUR on: June 19, 2014, 07:37:28 pm
HI!!!  smiley

Is possible that "Arduino" forgot my interrupt after one hour?

Do I need to remember it minute after minute?? Is this the solution or this one easy trick?

best regard u all

HI
is there any precaution to have when use something like:

Solenoid valve like http://www.ceme.com/prodotti_2.php?id_liv=1&id_liv2=4&id_liv3=8&id_prod=47 
and this Heating Pad - 5x10cm  https://www.sparkfun.com/products/11288 ???

On Power Driver Shield Kit from sparkfun https://www.sparkfun.com/products/10618??

it seams it don´t flow properly.

I´ve solder one wire from VIN to 12v on shield to get the power from arduino adapter,  is it bad? 

Want to make build my egg incubator  smiley-mr-green

thanks for u reply, really don´t have any idea for this...

Ill be happy with 1000 maximum...
The maximum on the UNO is 250.

Happy agin  smiley-razz

Hi Sir PaulS

tks for reply,

Quote
In my project, i need to write one time on EEPROM
Write what? The state of the switch or the time that the state changed?

the time switch had been taken...


this task may repeat for 5 hours.
Quote
How many times will the state change? That is the relevant piece of information, not the time that the sketch has run/has to run.

about aprox. 1000/1500, 3000 maximum!!

hi All,

In my project, i need to write one time on EEPROM, and them always read from EEPROM.

got no code for now, but what i attend to try is... on first time i turn on arduino, he´s read when I get the push button from time to time to write .. this task may repeat for 5 hours.. like:
 _____                _____________   _    ____                            _______
|       |_________|                   |_||_|      |________________|          |...........
   on        off               on           on/off               off                 on       off......

and when turn on second/third time gome same scheme...

is better to get millis and when arrive to some time/push, make an flag or something like it?

Never used EEPROM, anyone know some exemple like it???

TKS in advance

Hi!!

I didn´t get the way to breack and chek if temperature had some increase from 1st value, this values ca change, so the need to get always the current ambient temp....


any help? What shoul i learn to understand?
