Timing a low high event

evening, i'm working towards end goal of creating solenoid v8 engine, run arduino. have sainsmart hall sensor board, used sense top dead centre. need record time 1 revolution, can take time, divide number of cylinders , give me time between firing each solenoid 1 revolution. so there bit of backround start of project, need little help. i've looked @ stopwatch example , reworked time 1 revolution (or transition high --> low -->high -->low) (the sainsmart comparitor have 2 magnets in opposite poles). working should, i've realised going cause me issue going collect data every other revolution of engine because working stop watch, on first revolution see low high low start , stop timer, wait further set, i.e. time every other revolution = no good! have @ code please , see if advise me go here? guess needs start timing when sees 1 transition high low, time ever set of low high low, , @ end of each low high low save time taken "onecycle". code: [selec

salve sono uno studente di ingegneria elettronica con la laurea triennale che sta studiando per la laurea specialistica. vorrei acquistare un oscilloscopio digitale da collegare al pc via usb per iniziare vedere e realizzare qualche circuito anche casa. il budget è limitato, siamo sui 200 euro. su internet di buono quel prezzo ho trovato poco o niente. l'unico che sembra avere buone caratteristiche è questo: http://www.almasistemi.it/description.asp?item=94 ma mi sa di cinesata. che cosa mi consigliate? quote from: ireon on jan 15, 2015, 08:51 am ma mi sa di cinesata. che cosa mi consigliate? soldi buttati, è una cineseria, con quel budget nuovo puoi comprare solo questo , owon non è rigol però almeno è decente, lo store è ultra affidabile, hai la garanzia e owon ha un centro assistenza anche in italia.

Timer?

anybody can help? i'm trying program timer function on button hold relay. so when push button, relay should hold for, 3 seconds , release. i not want use delay(); because nead other things while program runs! code: [select] #define relaypin 9 #define buttonpin 10 void setup() { pinmode(relaypin,output); pinmode(buttonpin,input_pullup); } unsigned long triggertime=0; void loop() { unsigned long t=millis(); //assume relay active low //(most are) if ((t-triggertime) > 3000)   digitalwrite(relaypin,high); if ( digitalread(buttonpin)==low)   {   triggertime=t;   digitalwrite(relaypin,low);   } } Arduino Forum > Using Arduino > Programming Questions > Timer? arduino

Paper on science (astronomy) use of 3-d PDF

hi folks, for of interested in seeing how 3-d pdf can used in physical sciences might see this paper . while subject area of paper 3-d pdf astronomy publishing, equally applied many other areas of science. the paper covers techniques such plotting point distributions, plotting 2-d histograms, isosurfaces different levels controlled javascript, , volume rendering in 3-d pdf. thanks go couple of people on list (esp. gbeardsl) assistance acrobat 3d issues. the paper reference arxiv:0709.2734v1 . cheers - david. david, obviously, paper has been typeset latex. therefore, have used latex package `movie15' inclusion of 3d models pdf without need acrobat-3d. of course, have needed deepexploration righthemisphere.com (where acrobat 3d-plugin licensed from) vrml u3d conversion. probably, have saved lot of money because cheaper ;o). alexander More discussions in Rich Media & 3D adobe

Multitarea apropiativa o “preemptive multitasking” para Arduino UNO

hola: soy nuevo en el foro y este es mi primer mensaje. hace algún tiempo hice una multitarea para manejar 5 motores de un brazo robot con un arduino uno. lo probado bastante y me funciona bien, pero no tengo otras tarjetas de arduino y no se para cuantas funcionaria, o si solo funciona para la uno. si alguien le interesa probarla, adjunto un comprimido con la librería y con un pdf explicativo. el código también esta explicado. la probado con librerías como servo, lcd, serial, con delay(), milis(), etc. y no encontrado ningún problema. lo mas difícil que encuentro es darle la memoria justa para poder arrancar el máximo de tareas. agradecería me comunicarais los errores que encontréis, para solucionarlos. gracias. yo te felicito. fui uno de mis trabajos finales en ingeniería. por otro lado ten en cuenta que no debes hacer doble post (hay dos post de este mismo tema). asi que lee las normas del foro. tu librería es similar freertos para arduino. buscala y m

How to adjusst perspective angle ?

is possible adjust perspective distortion ? or setting camera len manually ? ( in both acrobat 3d , 3d toolkit ) thanks in advance perspective distortion depends on fov (field of view), aka aperture angle of camera, set 30 degrees on embedding. larger angles lead wide angle effects, while reducing fov 0 approaches orthographic projection. it seems impossible change fov during embedding in acrobat. changed programmatically via `fov' property of camera object. alex More discussions in Rich Media & 3D adobe

dhcp server using debian jessie - Raspberry Pi Forums

i've read lot of posts on setting simple private dhcp server using raspbian jessie. bit surprised see systemd (systemctl) init system. has set dhcp server using jessie? if do dhclient.conf settings? not need nameserver since networking privately. thank you, cwc want set network offline , ip addresses dhcp server hosts running minecraft each youngsters networking , ip address among other things. if want set local dhcp server should install dnsmasq, simplest set up. should set static ip address in /etc/dhcpcd.conf (look "static" settings in "man dhcpcd.conf") , make sure don't have other server handling dhcp on local network. systemd isn't issue. raspberrypi

Pipe sensor

there's lots of examples of metal detector projects arduinos , i'm interested in pipe sensor (put next wall see if there's pipe behind before drill hole). does have examples of or can offer me advice on how adapt metal detector project purpose. i'd rather use off shelf inductors wrap own coils. thanks, j and how want destinguish if detected metal cables, pipe or reinforcement of wall? guess need x-ray wall ;-) Arduino Forum > Using Arduino > Sensors > Pipe sensor arduino

Impostare layout da tinymce editor... - Joomla! Forum - community, help and support

salve tutti, avrei il seguente problema... vorrei fare in modo che dall'editor predefinito di joomla si possa dare tutto il contenuto un layout due colonne dove nella prima si trovano soltanto delle immagini messe in verticale e nella seconda si trova il testo. ho provato inserendo una tabella due colonne e sembra una buona soluzione, ma se poi nella prima colonna inserisco un'immagine un pò più grande mi si allarga tutto il box del maincontent e mi esce fuori dai limiti della pagina. non si potrebbe fare in modo che l'immagine inserita viene automaticamente ridimensionata in un certo limite massimo oppure vi è una soluzione più adatta delle tabelle per impostare un contenuto 2 colonne? grazie come sempre! ho provato inserendo una tabella due colonne e sembra una buona soluzione, ma se poi nella prima colonna inserisco un'immagine un pò più grande mi si allarga tutto il box del maincontent e mi esce fuori dai limiti della pagina. prova dare una claasse fittizia all

Non volatile memory integration

hi guys i need general guidances next step in current projet - saving data. my project works on way similar scubadiving computer do: saving data sensors during short session between start , end trigger - each second during approximately 3mn-, , make these data available being analized in connected computer. data erased , memory free next session. far, worked on sensors connection , data computation triggers. the project using arduino nano because had keep miniature - sd card reader not option me. having considerd existing discussions subject, seems interesting use fram (i still don't know how amount of data need, not of first concern). does using fram makes sense such project? if so, there tutorial start with? should mount ship myself, or buy shield? thanks tips! can explain objection microsd? it seems me microsd smaller, simpler , have higher capacity other solution.
