Project Guidance / Re: Pressure sensitive floor
Last post by Chole - Today at 05:26 pm
Hmmm - sounds like that scene from "Raiders of the Lost Ark"  :)
Something similar but less dangerous as there are no chasms in the plan; yet.
This kind of looks like a 8x5 keyboard matrix.  So you could use 8 pins for columns and 5 for rows = 13 pins.  Might reduce the number of pins further with shift registers (SPI) or I2C expanders.
I already have a mega i thought of using for this, so number of pins are not a major problem unless this simplifies the project. The author of that project used nanos and 8 analog pins for 8 sensor pads for detecting pressure levels which i don't need. There is a fritzing breadboard schematic at the bottom of that page i'm trying to figure out.

Where do I start with coding this?

Sensors / Sensores para medir la velocid...
Last post by camilocienfuegos - Today at 05:26 pm
Hola a todos , disculpen me gustaría saber si existe alguna forma de medir la velocidad del viento  (m/s)  de un ventilador a través de un sensor en arduino , o en algún otro medio. Muchas Gracias.

CSV ist "Comma Separated Values" wobei deutsches Excel gerne lieber ein Semikolon statt Komma hätte.

Wenn String dir mühsam erscheint, vergiss es. Die sind nur pro Forma da, damit arduino ein bisschen wie Java aussieht.
Erfasse entweder die numerischen Werte gleich beim Einlesen, oder nimm lieber c-strings und strtok().

Software / Re: Vocales y Consonantes Visu...

Este es un display de cátodo común


Entonces cuando envías un 1 en el pin D2 del esquema, se iluminará.
Si miramos tu código, veo que para generar una A debes iluminar todos los segmentos menos el g.
Pero en su lugar tu pones 0 y un 1 en el g.
Es lo resolveremos facilmente, o bien reescribimos los arrays o podemos invertir las salidas.
Yo opto por reescribirlos.
Otra cosa que no me gusta es que tu definiste a vocal como una matriz 5x8 = 40 bytes y se pudo definir solo como una matriz de 5 bytes asi

Code: [Select]
// Declaracion Variables
int vocal = 0;
int consonante = 0;

// VOCALES
byte Digit[5] = {   // Configuración para catodo común?
     0b00010000,    // A
     0b01100000,    // E
     0b10011111,    // I
     0b00000010,    // O
     0b10000010};   // U   

// CONSONANTES     
byte Digit2[8] = { 
     0b00111111,    // b
     0b10011101,    // c
     0b01111011,    // d
     0b10011111,    // e
     0b10001111,    // f
     0b10111111,    // g
     0b00101111,    // h
     0b01110001};   // j
 

 bool btnVocalAnt, btnVocal;
 bool btnConsonante, btnConsonanteAnt;

// Formato Pines 
void setup() {
    for (byte i=3; i<11; i++)
        pinMode(i, OUTPUT);
    Serial.begin(9600);
}

// Contador Vocales
void loop() {
   
    btnVocal = digitalRead(11);
    if (btnVocal && !btnVocalAnt){
    vocal++;
    Display(vocal);
    delay(500);
    }
    btnVocalAnt = btnVocal;

    btnConsonante = digitalRead(12);
    if (btnConsonante){
    consonante++;
    Display(consonante);
    delay(500);
    }
    btnConsonanteAnt = btnConsonante;
}   
           
 
// Display
void Display(int V) {
    for (byte i= 0 ; i<8 ; i++) {
     digitalWrite(i+3, Digit[V] && (1<<i));   
}
   
    for (int k= 0 ; k<8 ; k++)  {   
      digitalWrite(k+3, Digit2[V] && (1<<k));   
    }                     
}

Solo te aseguro que compila. Dime como trabaja.
Si presionas el boton del pin 11, aumentas vocales y con pin 12 aumentas consonantes.

Arduino Yún / How to stream multiple traces ...
Last post by streamlet - Today at 05:22 pm
I am using Arduino Yun with data streaming service from Plotly (https://plot.ly) to monitor temperature and humidity in a real-time manner. After following the instructions on https://github.com/plotly/arduino-api/tree/master/plotly_yun, I am able to stream both temperature and humidity traces into one graph. However, since their values differ a lot (e.g. temperature ~ 25 in degC, while humidity ~80 in percentage), it would be better to stream the two traces into two graphs respectively. A multiple-graph approach also facilitates visualizing more sensing data (e.g. air pressure, UV level).

There is example code for streaming multiple traces to multiple graphs on https://gist.github.com/chriddyp/11222798. However, it applies to Arduino Uno + Ethernet shield instead of Arduino Yun which is at my hand. I wonder is there any way I can implement streaming multiple traces to multiple graphs with Arduino Yun. Any suggestion is welcome. Thanks.

Last post by Ernst16 - Today at 05:20 pm
Ich hab am 15.5 die Bestellung bei den Jungs gegeben, heute am 25.5 kamen 11 Platinen an.
Montag hab ich die Info bekommen dass das Packet rausgeschickt wurde.
Versandart hab ich DHL in HongKong Express (4-7 Workdays) 22.66€ gewählt.
Postbote wollte nochmal 35€ haben, wofür?
PCB Größe hab ich 10x15 gewählt.

Also wenns immer so schnell wäre, wär die Welt i.O..
Danke - genau das hat mich interessiert. Die 22,66 waren die Expressversandkosten? was haben die Leiterplatten gekostet ?.
Auf der Homepage springt das so komisch herum .... gebe ich 10Stk, 10x10 ein sind 11,90€; bei 10x15 43,90€ ? - ist beides extrem günstig - aber bei den 10x10 kann das wohl nicht sitmmen.
PS über die Postzuschläge ärgere ich mich auch immer (EinfuhrUST, Bearbeitungsgebühr, Zollabfertigung ... Deppensteuer usw.)

Can anyone give me a rough time estimation of the repeatability?
Without knowing how you are sending the values? No. Binary will be faster; ASCII will be easier to sync and check the validity of.
