1  Using Arduino / Interfacing w/ Software on the Computer / midi to the device, output a wire per note on: August 02, 2013, 11:24:49 am
talking the  device.  looking for exemple of work that looks like it ,
or somebody to do it.


taking a midi file and outputing a current in the right place,   
note start, current start , note end current end ,
 the midi files has to be able to be sent just before it is played or earlier. from a device no matter wich one.

thought sending usb. 
and using two
mega 2560
http://store.arduino.cc/ww/index.php?main_page=product_info&cPath=11&products_id=196
because ineed 100 out
 

thanks
2  Using Arduino / Microcontrollers / using a hub controller on: July 20, 2013, 09:04:04 pm
ho w to talk to this http://www.cypress.com/?docID=39996
hub controller 

I would need to take a midi file and change it into , 16 out , for each note .

at each note, start and end, it send the signal made of 16 out,   

thanks for work done previusly , informationss, 



 

 
3  Using Arduino / LEDs and Multiplexing / dip sip schematic on: July 15, 2013, 08:56:50 pm
Hi   , I would need a  schematic,  or a explanation,  for using :  

all in 100mAh, 4 volt
a coil .150 mm diameter, 40meter of wire, ,
a sip, dip switch,
a rf receiver,  
in multiple quantity.

RF receiver gets the information
send it to 100 sip, dip  switch
voltage go to the coil for the switch that went on.
  
voltage ----------- switch
         \                /  
           rf receiver  

I tought it is a way of doing what I want but I work on it now.

Hi,
I look in fact for the software.  for the arduino. for receiving , playing, sorting, and sending the midi .
. the user make a play list.  have it played when the arduino  send the amount of voltage required in each place.   


also  I will need to calculate and confirm  charecteristics of  the  coil  to use.

thanks.

hi
I want to  a upright piano.
make it play   by itself, probably wireless.
 

user sending file
arduino   activitate elctromagnet, coils, multiple at a time.
to play it.

thanks


tought using
-Arduino DUE x2
-custom made coils
 
if somebody did it before or could give informations.
thanks

thanks,

what DC power source could i use
If I want to use th IR with a 0.25 Amps magnet, on 4Volts.

does 2 or 3 AA battery would work.
or other precise type of battery.

thanks,

it is for outside use, but inside a box, air circulate, over 32Farenheit or 0celcius.

when outside air is hot, will the IR see changes.

if you have suggestions for a similar product, but very low definition camera.  I may check.

 thanks,

what does very small 4v relay is in comparison to the magnet I described,
0,81wire,  40m 1v 1Amp

is it all, the battery, the IR detector, and the relay, on 4v
or adding a transistor if on 5v.
no controller.

Hi , I would like to have assemble a thing that uses this. 
http://www.dfrobot.com/index.php?route=product/product&path=36_58&product_id=119#.UMUgjBfDjZf

but instead of the alarm it is a switch that turns on. 
what are the other things do i need to have it work.
means it activate when it detect a movement.   

the switch is not selected yet,
one option is an electro magnet : 1v, 1 amp, 40m wire, of diameter 0,81mm. 

and idon't know what else is needed to answer this.   

thanks for you time
10  Using Arduino / Sensors / when image change it goes on for 1 seconds on: December 07, 2012, 02:32:04 pm



Hi, it is for activating an electromagnet when the image change on the camera.
what's needed execpt the electromagnet and the camera.  but the camera can be on the circuit.

is there kits or should it be produced.

1v to 3v, 1amp, electromagnet.
want it to be activated as one person passes in front of the camera and change the image.

1. a person passes
2. the image changes on the camera
3. the solenoid valve closes

thanks,

Hi,
one at a time or number from 1 to 1000

I prefer if it stay under 0,40$ per output.

I have two idea but there is certainly more

1.  an integrated circuit that goes on or off when it receives its code. and use one on each device. sending all the codes to all the switches.  and it only goes on or off when it is their codes.

2. a circuit that turns on off, each output. all in one.  but i found only ones with not a lot of output.

it seems to me the 1. is more simple, less expensive for a for over 1000. but it maybe 2. or another one.
does it exist or should it be produced.

thanks,

Hi, I would need a thing to activite 1000 or more devices on or off simultaneously.

Thanks
