lately i've seen, on other sites, questions being asked difference between joomla , mambo - , honest people don't answer.  without knowing history of 2 projects, it's difficult explain differences. so decided relax bit week , writing on history of mambo best can remember , of differences, in opinion, exist between 2 projects. you can find here: http://dev.joomla.org/component/option, ... d,33/p,79/ of course unashamedly biased in conclusions on project "has edge" overall i've tried stick facts best can remember them without going yucky details during our times of trial.  i've included simple diagram showing versions of mambo, , later joomla, progress , providing governance @ time. hopefully serve solid starting point people asking basic question. minor things: typo: arpil 2001 the other thing - have explained code diversity more (like 4.5.3 , 4.6 being 4.5.2.x based , j! 1.5 being based on 4.5.3, once pt in) Board index O...

hello! i know base of transistor must have resistor connected it. problem don't know resistor use! i've seen examples using 1k, 10k , 220 ohm resistors. how can determine resistor use base? thanks! it depends upon transistor using , how current expected carry. tell more! -- the rugged audio shield : line in, mic in, headphone out, microsd socket, potentiometer, play/record wav files Arduino Forum > Using Arduino > General Electronics > Transistor Base Resistor Choices? arduino

hey guys, here's situation: i'm using code here read button presses tv remote: code: [select] #include <irremote.h> // use library int receiver = 11; // pin 1 of ir receiver arduino digital pin 11 irrecv irrecv(receiver); // create instance of 'irrecv' decode_results results; void setup() {   serial.begin(9600); // serial monitor output   irrecv.enableirin(); // start receiver } void translateir() // takes action based on ir code received {   switch(results.value)   {     case 0x70: serial.println("menu/exit"); break;     case 0xa90: serial.println("power"); break;     case 0x290: serial.println("mute"); break;     case 0x90: serial.println("ch +"); break;     case 0x890: serial.println("ch -"); break;     case 0xa70: serial.println("select/ok"); break;     case 0xc90: serial.println("vol -"); ...

buenas tardes, soy nuevo en esto de arduino, no tengo mucha idea de electronica pero quiero ir aprendiendo poco poco. quiero monitorizar una bateria de caravana de 12v, solo me interesa en el rango de 11 15v aproximadamente, seguramente de 10 15v será mas facil. tenia pensado hacerlo con un divisor de tension pero aqui el rango lo ajustaria de 0-15v con lo cual la precision seria menor que si solo monitorizara 10-15v para aprovechar solo ese rango. es posible con un a.o diferencial (o como sea) restar los 10-15v 10v para adaptarlo al rango de 0-5v de la entrada analogica del arduino y asi aprovechar el 100% de precision de la entrada analogica?. como tendria que ser el circuito? muchas gracias. no es necesario usar un ao diferencial, tendrias que usar uno configurandolo como amplificador sin invertir. ojo que para tener todo el rango dinamico, necesitas uno rail-a-rail. si además tienes que restar, tendras que pone una señal de referencia de 10v para la r...

sorry relatively new arduino.  wanting transmit code in ascii device operating @ 9600 baud , want graph example in graph form ex. battery volt. having trouble figuring serial protocol use , pins use.  device transmits @ 5 volt signal , has rj 45 plug on (phone plug 6 wires).  starting appreciated. in advance. if new should start spending day or 2 @ tutorial section of arduino.cc there lot learn including serial communication. serial uses pin 0 , 1 , minimal sketch captures string device looks like code: [select] char buffer[80]; int idx =0; void setup() {   serial.begin(9600); } void loop() {   if (serial.available() >0)   {     char c = serial.read();     buffer[idx] = c;     if (c == ';')  // check ;      {       buffer[idx] = 0; // end string       // buffer contains string       // can read data       ...

arduino library allows create tiny 20x16 pixel bitmap (raster) display on character-only lcd display. typical drawing functions line, rectangle, invert, etc. control right down pixel level. works both standard liquidcrystal library francisco's new liquidcrystal library. example sketchs available on project website , part of library download.  try out , let me know think.  plan on adding additional features in near-term. lcdbitmap library arduino here's sample of in action: new in v1.6 bitmap_range_chk bug fix. new in v1.5 4bit method works without new liquidcrystal library (was supposed work way, oversight on part). update switch optional on functions, defaults no_update. new in v1.4 fixed few problems bargraph function. further optimization range checking. compatible arduino 0023. lcdbitmap library v1.6 download tim eckel i need check out! cheers Arduino Forum > Using Arduino...
