i've read bits on reducing ethernet timeout in arduino 1.0 using: w5100.setretransmissiontime(0x07d0); w5100.setretransmissioncount(3); unfortunately, not seem work arduino 1.0 , dhcp ethernet call like:   if (ethernet.begin(mac) == 0) { instead, no ethernet cable inserted in rj45 jack, have wait several mintues timeout....not . i've tracked through ethernet libs , looks i'm stuck in loop inside of sendudp (in socket.cpp) waiting ok or timeout which, unfortunately, seems take several minutes (!) when there's no ethernet connection. the call trace ethernet.begin like: w5100.setmacaddress() w5100.setipaddress() dhcp.beginwithdhcp() dhcpupdsocket.begin() send_dhcp_message() sendudp() (i've messed values passed timeouts beginwithdhcp too, no avail) how others dealing apparent lack of functioning timeout on ethernet.begin when using dhcp?   it nice if there instant way tell if, say, there's not ethernet cable inserted in jack.... ...

hello, being new forums (but not arduino!) hope right area questions... i want figure out way few things logged on sd card either uno or mega... not sure 1 yet, have see how many pins need. but anyhow, goal this: 1- user inputs number matrix keypad (i.e. 1 or 11 or 12). whole numbers only, , positive numbers 1-99 2- arduino reads sensor, depending on button pressed (let's call button 1), , logs value in .csv (i.e. 1,7.4) 3- user repeats step one 4- here gets interesting: if user inputs 1, presses button 2, want arduino revise .csv entry 1 to, say, 1,7.4, 8.2 i do not want multiple entries in .csv like: 1,7.5 1,8.2 1,9.0 is possible? the application of project require 1 sensor reading (like temperature) of 10 samples (each assigned number 1-10). then, temp sensor switched out different sensor , same samples read, different variable. eventually, ideal .csv entry 1,x,y,z so can this? can figure out basic sd entry tasks, , i'll integrate lcd , few led indicators. data l...

hi there, i have been reading lot on controlling solenoids playground , various websites. want able control sprinklers website. my solenoids need power has following specification: • solenoid: 24 v ac • inrush volt-amp: 24 v ac-11.50 va • inrush current: .4 amp • holding volt-amp: 24 v ac-5.75 va • holding current: .2 amp is still advisable make use of separate 24v ac psu , use opto-couplers switch solenoids? or using transistors better option? since using 24volt ac traic needed , not transistor. traics used switch ac devices. watch video has circuit. moc3041 because isolates micro controller load. http://youtu.be/5tt4zakpdpw don Arduino Forum > Using Arduino > Project Guidance > Controlling home sprinkler system arduino

ok, i decided make new topic. have been trying , still can't make work. i made web page has bunch of buttons when rolled on shows image , when clicked opens video player on layer 50 on image. can not figure out how make movie(flv player in swf file) either unload , stop when flv player done or close , stop when hit premade button has correct code tutorial book. i have flv file set progressive download in seperate swf file , using premade button lynda flash 8 book button closes flv keeps playing shouldn't. my ultimate goal have swf movie flv file close flv file finished playing. here's code swf file new close button. on (release) { unloadmovienum(50); } here's code main site: stop(); button1_btn.onrollover = function(){ gotoandstop(2); } button1_btn.onrelease = function(){ loadmovienum("movieplayer1.swf", 50); } i'm starting go crazy appreciated. jason first _level50, not layer. layer tool organizing artwork in authoring environment. layers d...

moin zusammen, habe gestern ein camera module bekommen. leider scheint das ding jetzt nur nicht zu laufen. habe raspbian schon neu installiert, alle updates gemacht (inkl. firmware) und natürlich auch per raspi-config aktiviert. wenn raspistill oder raspivid starte bekomme ich die fehlermeldung: code: select all mmal: mmal_vc_component_create: failed create component 'vc.ril.camera' (1:enomem) mmal: mmal_component_create_core: not create component 'vc.ril.camera' (1) mmal: failed create camera component mmal: main: failed create camera component mmal: camera not detected. please check camera module installed correctly habe dann mal versucht die led auf dem camera module zu schalten per gpio, das klappt wunderbar. memory-split hab ich auch schon diverses probiert. hat vielleicht jemand von noch eine idee ich falsch machen kann? gruss stefan steck die kamera mal in den 1.
