Re: No com port for second arduino

Posted: 10 Mar 2013 12:47 AM PST

So 1 is not working at all?
When you plug it into the PC(no other arduino is connected) does the PC recognize that something is plugged into the USB port?
If not it may be something wrong with the connections or the USB interface.

In fact i use them because i connect the motors + the photo resistor + the ping sensor to the +5 V pin of the arduino board . If i cut the capacitator and the diod,isnt there risk for this pin to burn because of the higher voltage ( about 6 volts ) ?

una delle funzioni di questi moduli e' proprio di ricollegarsi all'ultimo device usato. se cambi device, ad esempio ti agganci ad un telefono, poi dovrai ridare i comandi.

Once you have decided that it is night,   don't even consider making it "day" again,  until 8 hours have passed.

we had this issue with a supplier at my work, they wanted to not print values on 1% resistors, why I dunno they were 805's, they only did it on a few models.

we fought it, threatened to change suppliers, they complied ... who knows, I think its just la...

Come al solito non avete chiari i concetti di precisione e risoluzione, la prima è un valore percentuale e indica di quanto può discostarsi la misura dal valore reale, dipende esclusivamente da come è fatto l'ADC, la risoluzione non è la tensione minim...

Very good question. I have looked at ARM chips as well as the Pi.

I didn't mention because i was on the Arduino forum but this will be on a He balloon floating 4-8 feet above the ground....SO the Pi is a little weighty where the Mega i can fab a custo...

le POE sert a alimenter la carte réseau ou le routeur à distance via le rj45.

l'avantage de l'alim pc est que tu as tous les voltages de dispo et quelle fournit assez de puissance en ampères.
en plus pour la résistance ou la lampe en 220v, tu peux récu...
