Hi,

I am working on the arduino Fio but I need more analog channels (the 8 analog I/O are not enought). I want to add about 8 other analog inputs. Multiplexer seems really difficult to use, I found some I/O Expander such as (PCF8574), that seems easier...

Stepper motor with driver board problem

Posted: 17 May 2013 02:59 AM PDT

Hello,

I' m using a 28BYJ-48 5Volt steper motor together with a driver board.
It is working fine, but my question/problem is that my leds on the driver board are still on after the motor stops.

Is there a way to solve this? At startup the leds are off....

Can you explain what you mean when you say that things don't work ?
What does happen when you try ?

Re: Relais pour piloter prises électrique

Posted: 17 May 2013 02:58 AM PDT

Bonjour,

Vous parlez d'alimentation mais il s'agit bien de celle de l'Arduino lui-même ? Si c'est ça je ne comprends pas trop le rapport avec la puissance que l'Arduino lui même est capable de sortir (200mA il me semble) et donc ça va limiter le nombre...

Re: measure 16 digital frequencies

I'm not sure a mux will help you, but you could fairly easily expand the example to use the six external interrupts on your Mega, and then maybe look at pin change interrupts for the other two.

PICrouter #piday #raspberrypi @Raspberry_Pi

PICrouter by tkrworks:

PICrouter is a versatile and prototyping board specialized for Open Sound Control.
The main function is to communicate between OSC and USB-MIDI/HID.

PICrouter will be an useful with the following purpose.

Develop an OSC/MIDI/HID controller for music or visual.

Study a PIC32 microcontroller.

Study a communication with usb and ethernet.

Demos and more here.

Each Friday is PiDay here at Adafruit, be sure to check out our posts, tutorials and new Raspberry Pi related products. Have you tried the new "Adafruit Raspberry Pi Educational Linux Distro"? It's our tweaked distribution for teaching electronics using the Raspberry Pi. But wait, there's more! Try our new Raspberry Pi WebIDE! The easiest way to learn programming on a Raspberry Pi.

We now have Raspberry Pi Model B with 512MB RAM in stock and shipping now!

Avevo capito bene, grazie ... comunque peccato sarebbe stata utile un po' di eeprom oltre alla flash già presente.

ciao

We usually identify ourselves with the Arduino, so "Vout" and "Vin" sound rather strange.

But from the voltage divider point of view its perfect smiley

Re: Scrivo su SD ma il file è vuoto.

Posted: 17 May 2013 02:20 AM PDT

Può darsi che mi abbia tratto in inganno, quindi hai un arduino uno, uno shield sensor che credo abbia i pin in parallelo all' UNO, e come SD è uno shield solo sd o una scheda ethernet + sd?

i need arduino UNO in abu dhabi with servo motor... so plz let me know if any of you can help me... my cell no is 0501339930
its too urgent smiley-cry

i have already ordered online but that will take some time and i need it by 2mrw

Via evilmadscientist.com:

Hey all you Raspberry Pi and Eggbot lovers: over on Instructables, user crgfrench shows how to load Inkscape and the Eggbot extensions on your Raspberry Pi. He even goes so far as to mount the Raspberry Pi on the Eggbot for compact plotting.

Re: Direct AT Commands to shield (for getting time)

Posted: 17 May 2013 01:53 AM PDT

Hi,

I had the same issue too and I solved it in this way:

for sending an AT command, you can write

Code:

…

theGSM3ShieldV1ModemCore.println("AT+QTONEDET=1");

…

if you want the answer, you can write

[code]
…

theGSM3ShieldV1ModemCore.println("...

Help me make sense of these bits

i am trying to decode an air conditioner IR remote. and i could use some help understand how these bits are set
i have 2 possible sets of data, depending on how the incoming data interpreted. the are bits are just inverted in each of the sets.

Re: Wanting to build a frequency generator.

I suspect you just need to match the camera shutter frequency (or a multiple of it) so if your using a PAL camera it's 25Hz (or maybe 50Hz if using interlace) and if your using NTSC than make it 29.97Hz

Posted: 17 May 2013 01:49 AM PDT

Bene... non ci ho capito niente smiley

Purtroppo di elettronica ne so 0... l'idea era comunque quella di usare il transistor come interruttore... è possibile quindi?
Devo acquistare un transistor PNP o si chiama in un altro modo?
Devo accendere 6 led... no...

Bonjour
Ce n'est pas aussi simple que cela.
Il faut voir si les boutons de la télécommande ne sont pas multiplexés. Par exemple, si la télécommande à 12 boutons :
si tous les boutons ont un de leurs contacts reliés ensemble et au 0 V, on peut utiliser ...

The Oreo Separator Man at Maker Faire

David Neevel made one of the best viral videos of 2013, the "Oreo Separator Machine." It is dry-funny and it stars his whack machine that removes the white [disgusting] faux Oreo cream. He is a maker who knows how to tell a story. He is a copywriter at Wieden+Kennedy in Portland. […]

Re: How to keep compiled files in arduino ide

Posted: 17 May 2013 01:02 AM PDT

Thanks Pito it works.

Do you know how to set relative paths? I would want to make it portable and be able to set the Arduino folder in any place. What do I have to do to define a path inside Arduino folder?

Something like /arduino/compiledLibraries ...
