how to do a get request by a website from the arduino

hi, i'm known arduino , c. but have no knowledge of websites. so started html 5 document create same screen same code , routines use in arduino code. so far good. i see after playing around can same website tft screen on tft screen update values during loop. but how can without refreshing complete page. on website. i have idea can javascript , additional js file. files found pretty big. i don't want use sd store data  want minimize overhead adding complete java file code. i tried read java file unreadable way save it. miss the  request values arduino. i build loop within website overwrite data updates values on site without refresh of page. http://jl-p.getmyip.com:3001/test1.html anyone yidea how request values once in while website. without adding java source files. johan you can put simple refreshing data pages in frames in static main page. can little more elaborate in below tutorial. http://startingelectronics.com/tutorials/arduino/ethernet-s

How to power 16 channel relay

Servo Question about Torque (Physics/Mechanics Problem)

hi, i total beginner. bought arduino month ago. first projekt automated nerv-gun turret. so far have got basic setup , coding covered. next step getting parts , building it: so big question right is: how torque should 2 servos have? so far specs: size of gun 0.8m; weight 1.4kg i want control rotation (180°) , tilt (90°) 1 servo each. after google/wikipedia/etc. came this: torque = * "alpha" the moment of inertia = 1/12 m * l² (i figuered assume gun long stick equal mass distribution serve needs of accuracy. plan on mounting @ center of gravity) so if want gun turn fast , stopped quickly, without wobbling have observed in many similar projects, how strong servo must get? quote torque = * "alpha" "alpha"?

Limpiador de paneles solares automatico

buenas, estoy viendo como hacer un sistema de mantencion (limpieza) para paneles solares aqui en chile, y me hice con una placa de arduino uno. tengo pensado hacer algo similar las plumillas de automoviles, o algo como un paño que limpie solo el panel y luego se "guarde". no soy experto en electronica, pero identifique como variable el tiempo (que tengo que determinar aun) en que el panel se ensucia y asi se realize la accion, por lo que tengo un datalogger para eso. de momento pienso realizar la limpieza con agua, en periodo de prueba, y ver si hay una diferencia respecto el agua desmineralizada. se como llegar fijar el tiempo en que se realiza la limpieza, pero no se como llegar un programa adecuado que haga la accion del limpiado (las plumillas, o algun paño como "telon"). hecho los tutoriales de artuteka y espero que me ayuden tecnicamente con la programacion. saludos. quieres la programación completa? bueno básicamente eso es bast

New to Arduino, Have what might be an over ambitious project NEED HELP!

hello, everyone.  asked if create arduino-controlled e-hookah.  clarify, 4 heating elements controlled 4 buttons, leds , pretty stuff that.  i'm new arduino said, , i'm not sure how go it, delaying me buying board until know need.  here's specifics: i need source (4) 3.7 volt outputs(one each heating element) , whatever i'd need run leds.  need separate batteries this, know, how control voltage going each heating element? beyond that(and being ambitious), how difficult make each output variable voltage, in controlled dial, within given range(roughly 3-4.5 volts).  add low power cut off well, these things can wait until figure out if works @ all! i'm thinking of 4 separate circuits, basically.  1 circuit each heating element each power supply. so i'm asking is:  i'm thinking possible?  can control voltage secondary power source?  how difficult be, 4 separate sources necessary, , having more 1 heating element make more difficult, if so, how much?

Else..if problem, I think. :( [Robot Rover]

Image
hello! i'm building little robot rover , stumped on something: works great going forward, reverse, , doing 0 degree turns; however, when tell 1 motor or other go, either both or not depending on motor.    =( the left motor if that's has done, not after has gone forward or reverse, both go. right motor doesn't when asked go itself. behavior between motors trades places when copy , paste  "if(rcount<sr) {.....}" after " if(lcount...){...}" instead of before. don't it. (why isn't there smiley face banging one's head against wall?) any appreciated!    also, disclaimer, i'm pretty new this; so, hope code isn't embarrassing.  thanks! code: [select] volatile int lcount = 0; volatile int rcount = 0; //motor l 1 int stby = 10;  //standby //motor l int pwma = 6; //speed control int ain1 = 9; //direction int ain2 = 8; //direction //motor r int pwmb = 5; //speed control int bin1 = 11; //direction int bin2 = 12; //direction int echo =

what is the output current going to led., schematic given?

what maximum current peak-peak going led. schematic given br1 bridge rectifier made of 4 1n4007 diodes ---max forward voltage 1000v , piv 700v ac supply wrongly given 220 v 230v ( rms voltage) , freq 50 hz the resistors of 30 k each. will led light @ current or not? max forward current led 60ma , minimum dont know. quote max forward voltage 1000v . i doubt that. reverse voltage perhaps, otherwise need @ least 2000v make sure bridge conducts! if a.c. sine wave should be, peak voltage 230 x sqrt(2) 325v.  call 320v round numbers, , allow small drop across diodes , led.  320v dropped across 2 30k resistors.  ohm's law 320v/60k = 5.3ma.

field test results - RFM69HW wireles module range test w/ GPS (see map)

i got around doing range test 2 rfm69hw modules.  if haven't come across them, they're pretty similar nrf24l01, come in 915mhz frequency instead of 2.4ghz.  the -hw chip high power 20db version.  one complication rfm69hw not 5v tolerant.  but, cool thing rfm69 chips antenna can hook-up wire solder onto chip, it's customizable.  knowing nothing antennas, use 6" section of hookup wire shaped in spiral.  these modules seem have greater distances pa version of nrf24l01.  i use different, less congested frequency wifi. the gps chip ublox 6m.  the gps arduino has ublox gps , rfm69hw wired it, transmitting every second.  but gps location requested every 3 seconds.  not sure if makes sense...i wanted more transmissions of signal gps requests. the base station arduino connected computer @ home, via usb, serial monitor displaying every time receive location transmission gps arduino.  the struct gps arduino sending time stamp, longitude, latitude, , basestation prints o

right column disappears when blog list is used - Joomla! Forum - community, help and support

what change right column on 3 column layout doesn't disappear when view blog format of content items category? right column instance, has extcalendar , ads. extcalendar, in it's module setup, selected show. so, overriding removing right column. i'm using rocketthemes.com template put together. http://s178238539.onlinehome.us/index.p ... &itemid=32 check see if there "if" around right column commands in template.

ciao ragazzi, volevo cambiare grafica al mio sito e perciò anche il template.non ci sarebbero problemi di sorta da parte mia creare un template normale per un sito. l'ostacolo sono nei tag di joomla e nel pachetto di installazione. detto questo ho scoperto che con nvu e il plugin per joomla è possibile superare questi problemi. ho installato tutto, ma non come farlo funzionare.. qualcuno ne sa qualcosa?se voelte vi linko il programma (che lo trovato sullo stesso sito di mozilla) e l'estesione (basta una googlata) grazie in anticipo  il template occupa solo una piccola porzione di joomla. e' difficile, lo so, concettualizzare joomla soprattutto quando si cerca di confrontarlo con un sito statico. ricordati solo che il template non è altro che un foglio html farcito con qualche stringa di codice php... che dire il vero è sempre lo stesso. quindi tag di joomla non sono altro che un'aggiunta da fare al sito; per esempio se in una pagina statica sei abituato scrivere .....
