world invasion, aliens rise, who may save us ?


the Truth is that a few Hollywood's movies reached Kepler-452b due to a strange phenomenon that is very hard to be explained by every current physics theory, indeed Keplerian scientists do not know how explain how our digital waves had reached their space stations. So they have fallen in love with Gwen Stacy, which dies in the Amazing SpiderMan movie. On their alien world there are no spider men, their zoo show a strange kind of monkeys, they also have reptiles, dinos even if they don't have horses, dogs and cats, while their sharks are in the same evolution line we have with our monkeys.


After an half century of investigations, Keplerian scientists has discovered that almost the same kind of organisms is living on the Earth planet has lived on their planet, but their evolution path is different: they come from fishes, a smoothed collided mutation line which hooks up the blacktip shark(1) and piranhas(2) into an evolving DNA mash-up which achieved the stage of their gills perfectly compliant to the oxygen outside the water and so metabolized that they achieved new brain power.

Thousand and thousand years ago, they become the most intelligent species, and after hundred of millennium of evolution they become more intelligent than human beings, more aggressive, stronger. Now they are here, on the Earth planet, and they are also pissed off, because they have lost their planet, they have travelled too far, and once arrived here they want Gwen Stacy for their entertainment (Amazing SpiderMan part 3? 4?), they definitively do not like the Hollywood decision which makes themselves the human beings look like complete morons to their alien's eyes.

Intercepting a communication by the resistance, their Army commander said - "if human beings are not an intelligent life form, there is no reason not to kill all of them in order to take over the Earth planet! Killing Gwen Stacy from a good movie is the prove they are morons, but we will have a lot of good food" -

(2) locally known as serrasalminae species closely related omnivorous fish, on the Earth planet they are known as pristobrycon, pygocentrus, pygopristis and their evolution line ended with those stable sub familes, while Kepler's oceans had introduced an ancestor prototype, an unknown family called Protocatobrycon, which has a lot in common with the blacktip shark shark's DNA.

buenas.. el codigo lo tengo tal cual te lo envie.. tendria que agregarle entonces eso que me colocast de

// // Define config for Serial.begin(baud, config);
// #define SERIAL_5N1 0x00
// #define SERIAL_6N1 0x02
// #define SERIAL_7N1 0x04
// #define SERIAL_8N1 0x06
// #define SERIAL_5N2 0x08
// #define SERIAL_6N2 0x0A
// #define SERIAL_7N2 0x0C...
 

pero de esa manera? y lo otro que me colocast tambien? es q soy nueva programando con arduino.. disculpa

Arduino Yún / Re: Arduino Yun network config...
Last post by alexkes1976 - Today at 02:57 pm
I think I need to explain my problem better  :)

In my application, the Yun board is used as wireless AP, with computer connected to the wired LAN.
The AP has static IP address, and it is responcible for giving IP to any wirless clients, and connect them to the network.

This is my network file configuration:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config interface 'lan'
        option proto 'static'
        option netmask '255.255.255.0'
        option ipaddr '192.168.1.253'
        option type 'bridge'
        option _orig_ifname 'wlan0'
        option _orig_bridge 'true'
        option ifname 'eth1'

config interface 'wan'
        option ifname 'eth1'
        option _orig_ifname 'eth1'
        option _orig_bridge 'false'
        option proto 'none'


And this is my WIFI file configuration

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '11'
        option hwmode '11ng'
        option path 'platform/ar933x_wmac'
        option htmode 'HT20'
        list ht_capab 'SHORT-GI-20'
        list ht_capab 'SHORT-GI-40'
        list ht_capab 'RX-STBC1'
        list ht_capab 'DSSS_CCK-40'
        option disabled '0'
        option txpower '16'
        option country 'US'

config wifi-iface
        option device 'radio0'
        option mode 'ap'
        option ssid 'XXX001'
        option network 'lan'
        option encryption 'psk2+ccmp'
        option key '01234567'
   option hidden '1'


This configuration is actually working fine. Ocasionally, when I plug in the Arduino Yun, after some time being shut down, the configuration goes back to default (SSID=ARDUINO YUNmac......, and IP=192.168.240.1).
I would like to know the reason for such configuration reset and any way to prevent this.

Thanks,

Deutsch / Re: Bitte um Hilfe: Servo über...
Last post by guntherb - Today at 02:56 pm
Du bringst das was durcheinander:

nämlich Servo.h und analogWrite().

Das Eine hat nichts mit dem Anderen zu tun.

analogWrite() erzeugt einfach nur eine PWM mit 490Hz oder 980Hz (je nach Pin).

ein Servo braucht aber eine andere Ansteuerung:

Alle 20ms einen Puls.
die Länge des Pulses beschreibt die Servostellung: (die Wert sind nur ungefähr und können von Servo zu Servo variieren)
1000µs die eine Endstellung,
1500µs Pulsdauer ist die Mittelstellung,
2000µs die andere Endstellung.

Das macht nun die Servo.h
(nimm am besten eines der mitgelieferten Beispiele, z.B. sweep)

um ein Servo "anzuschalten" dient der Befehl myservo.attach(), um es wieder abzuschalten myservo.detach().
Den Winkel stellst du ein mit myservo.write().

letztlich wirst du aber erst herausfinden müssen, wie dein Servo reagiert, wenn du keine Pulse mehr sendest.

The reference schematic for the Mega2560 seems a bit confused, around the area of the RESET-EN jumper. The symbol for the jumper is shorted out by a wire below it. Is this a mistake?

I would imagine that the RESET netname ought to reside to the right of the jumper, not beneath it on a short. That way, it would either be connected or not connected.

Just checking I'm not going too mad...

Hi MartynC, thanks for your reply and the information.

I have read in the page you have posted, that if the ZS040 only accepts AT commands in uppercase. I will test it.
(normally I use lowercase)

But, when I try to pass it to AT Mode with the PIN34, the led always blink fast, never once each 2 seconds.

The datasheet indicates two ways to pass it to AT mode.

DataSheet says:
  How to get to the AT mode.
    Way 1:
      Step 1: Input low level to PIN34.
      Step 2: Supply power to the module.
      Step 3: Input high level to the PIN34. Then the module will enter to AT mode. The baud rate is as
                 same as the communication time, such as 9600 etc.
   
    Way 2:
      Step 1: Connect PIN34 to the power supply PIN.
      Step 2: Supply power to module (the PIN34 is also supplied with high level since the PIN34 is connected with
                  power supply PIN). Then the module will enter to AT module. But at this time, the baud
                  rate is 38400. In this way, user should change the baud rate at the AT mode, if they
                  forget the communication baud rate.

I have tested both ways but no AT Mode.

Any idea about this ?

Du nutzt die Servo-Bibliothek und schreibst trotzdem PWM-Werte auf den Servo-Pin? Äußerst konfus...
Mach dich doch erst einmal grundlegend mit den Funktionen der Servo-_library vertraut: https://www.arduino.cc/en/reference/servo
Einen vordefinierten Servowinkel bekommst du, wenn du bereits in der setup-Routine ein myservo.write(0); schreibst.

Project Guidance / Re: Multiple thermocouples
Last post by johnwasser - Today at 02:53 pm
1)  what exactly does the "Adafruit_MAX31855.h" library do?  is it a formula that converts voltages to temps or is it some sort of look-up table.
It puts a wrapper around the SPI interface to make the chip easier to use.  It reads the temperature from registers in the chip and formats the temperature into an easy-to-use number.

2)  is there some way I can view the programming code in the library.
Look in the libraries/Adafruit_MAX31855 folder in the folder containing your sketches.  There you will find the library sources.  All Arduino libraries are installed as source and re-compiled as needed.
