The signal level at -65dbm is not great.

Check you do not have a firewall running on the host you are trying to connect from.
The error message indicates the connection attempt is being refused (actively), rather than timing out.

Nrf24 Library problem

Hi guys,
I've just received 2 cheap NRF24L01 modules,
I've downloaded from github relative examples and relative library but when I try to upload one of the example sketch I got following error:

Wtf? I don't know ehat's happened to my website! The file are all puloaded!

I'll try your method but it seems how if the server is protected and i couldn't access to it, it shows parallel desktop information about the server, i think that my get ans...

Se l'immagine in seconda pagina e' quella della struttura dei controller (full bridge), allora no, non puoi connettere il motore a due uscite per usare un qualche trucco per invertirne la direzione ... magari quei controller lo permetterebbero (non pos...

Bonjour! Voici un petit programme fait en C# pour visualiser les trames échangées sur liaison série avec un arduino. L'application est très simple et je me suis dit que c'était pas mal de la partager.

Le programme fait la même choses que d'autre logici...

I seem to recall this came up a while ago. Anyway, this isn't an installation issue.

Re: INPUT_PULLUP with transistor

Posted: 15 Jun 2013 01:24 AM PDT

That circuit will work (although it might need the base pulldown resistor already mentioned), but why use the transistor at all? Just connect pin 4 of the CNY17-4 to ground and pin 5 to the Arduino input pin, with pin mode INPUT_PULLUP. That's the usua...

I would use a SSR-25DA or similar solid state relay.

Re: problem with Leonardo and firmata

I done it, Arduino ver 1.5.2 and firmata ver2.3.5

Sure I am the one who don't want to solve the problem

Re: Voltage Requirement

Posted: 15 Jun 2013 01:15 AM PDT

1. You always need capacitors on the input of voltage regulators, and usually on the output as well (unless the datasheet says it isn't necessary). Exception: the output capacitor of the power supply feeding the regulator can double up as the regulator...

Playing audio file using Due

I have a task in which I have to load an audio file and play it with arduino due using the dac pin and an 8 ohm speaker.....I am new to arduino plzzzzz help with the code and connections like the value of resistor that I should use with the speaker

Un placer.

Con el operacional configurado como diferenciador, si el + es siempre mayor que el menos con una alimentación del operacional entre +5 V y GND debería funcionarte bien. De todas formas comprueba las salidas porque el sensor lo tienes que al...

Struggeling to reduce power consumption's to a minimum

Posted: 15 Jun 2013 12:45 AM PDT

Hi. I'm trying to make my atmega328p use as little current as possible while in sleep mode. I don't need any functions at all while it's sleeping, I only need it to be able to wake up with an interrupt.

Right now I'm using the Power-down mode and at fi...
