ARDUINO CON BATERIA DE MOTO - PROBLEMA CON OSCILADOR DE CRISTAL

hola comunidad de arduino. soy nuevo en éste foro y aficionado la electrónica. me encuentro haciendo un proyecto para mi moto que consiste en controlar por medio de botones ciertas funciones como temperatura, activar motores, activar un ultrasonido, etc, con el fin de hacer un sistema inteligente que me arroje ciertos valores del entorno y los muestre en una pantalla lcd. el proyecto ya está impreso y lo alimento con la bateria de la moto que es de 12v y 7 amperios. el sistema esta regulado con el 7812 y el 7805 para el micro. el asunto es que el proyecto funciona pero por algunos minutos, luego se bloquea todo el sistema porque se quema el oscilador de cristal y tengo que cambiarlo para que vuelva funcionar, pero me pasa nuevamente lo mismo. ¿qué puede estar pasando? ¿qué estaré haciendo mal? gracias de antemano sus respuestas. hola. ¿puedes mostrar un diagrama de cómo están conectados los componentes?

Ssr insufficient current from arduino?

hello everyone i have r3 board wiring fotek ssr control 240 vac load (light bulb). know circuit works because load turns on when input ssr connected 9v battery. when connect ssr arduino (say instance 5v , gnd pins),  ssr turns on (led on ssr flicks on) load doesn't. ssr input side reads 5v on multimeter well. i'm wondering if it's current issue since input voltage within correct range ssr (3-32v). any thoughts? where did buy ssr ? can give link ? did buy @ ebay or amazon ? perhaps fake. most ssr need 3v or more , few milli-amps. that's perfect 5v arduino board. not current issue. perhaps wrong ssr. can test somethine else ? example 5v power supply ?

Hexachrome or Mutichannel in Layers

does know if has been done accommodate hexachrome in photoshop instead of or cmyk? the reason ask because extremely useful have more 4 working channels without having resort multichannel (which doesn't work in layers). with 4 working channels, artwork can made in false colours using example cyan channel represent reflex blue , on. 6 working channels better, better still unlimited number of channels in unlimited number of layers, spot colours can designated , separated such. this isn't problem in illy, why problem in photoshop? typically hexichrome plates made rgb file during rip process... if plan on using more 4 colors in photoshop file, keep layer set dedicated color, when artwork done flatten out layer set, fill black paste spot color channel... you couldn't ever have unlimited amount of process channels. think of how difficult pressman aline line screens no dots hit each other... most printers mad if add 1 screen 4cp job.

Issue with 25V voltage sensors

hi all, forgive newbie question having problem.  want measure voltage on scalextric track (slot racing).  maximum voltage 19v.  i have spliced controller handset lead have 2 additional leads coming off feed sensor such in attached diagram (red vcc, green gnd).  arduino connections a1 (analog input 1) , gnd.  works fine, though readings gathered noisy. of course there 2 tracks (cars) on scalextric set!  however, when connect second controller second voltage sensor (same schematic, analog input 2 , other gnd on arduino) car in first track takes off without pressure on controller.  there short in circuit, there path created return current first car, continuity test shows no obvious issue.  have idea should start looking issue? many thanks, stephen i'd love help, need few things first: 1. post code in </> tags (read "how use forum" post)!!!!!! 2. 25v sensor? 3. m device in picture provided? 4. what purpose of arduino? 5. can provide pics

buongiorno ragazzi, è n pò che non riprendevo arduino, ora ho ripreso ad usarlo, mi stavo cimentando con la schield ds1307, allora ho caricato lo scketc e non mi da errore, ma quando apro il monitor mi dà solo lettere e numeri strani la velocità della seriale nella maschera che hai postato, in basso sinistra (combo) deve essere uguale alla velocità che è impostata nello sketch dalla  serial.begin Arduino Forum > International > Italiano > Software (Moderator: leo72) > problema stampa su monitor arduino

Color sampler tool prefs

hi, working on project involving colour matching large amount of rock samples using ps cs2. have found cmyk gives better output comparisons need able make 6 samples per image. have wish list of modifications make tool: 1) way change sample size 10 x 10? 2)is possible have output cmyk in info without having change each sample? 3) way have more 4 samples per image? thanks in advance can get. cheers tim 3a) nope. can't more 4 samples. 1a) create fixed size marquee @ size want. click create selection want sample. then, go filter menu ⇒ blur ⇒ average. now, selection still active, mash "command + j" shortcut place copy of sample/averaged area, itself, onto own layer. reactivate original layer , pick new place sample/average. do many times need. 2a) in info palette, click on little eyedropper icon display menu. change cmyk, or whatever else want.

arduino genuino micro

guten abend liebe forumsteilnehmer. mit dem arduino mega habe ich eine lichtsteuerung mit dem bluetooth-modul gebaut. das funktioniert auch prima. danach habe ich die schaltung mit dem arduino genuino micro gebaut und es funktioniert nicht. das signal wird nicht vom micro erkannt. angeschlossen habe ich bluetooth modul den rx und tx pin. könnt ihr mir bitte heolfen, wie ich dass zum laufen kriege? da der micro ganz andere pinbelegung hat, kann das der fehler sein. zeig uns deinen sketch (code-tags verwenden, schaltfläche </>) und das schaltbild.

Why does digitalWrite HIGH vs digitalWrite LOW take different amounts of time?

Image
i got oscilloscope , fun, thought i'd put quick sketch toggle output fast loop run on uno. code: [select] #define jpin  8 void setup() {   pinmode(jpin, output); } void loop() {   static int = 0;     if(i++ & 1)     digitalwrite(jpin, low);   else     digitalwrite(jpin, high); } i found high time longer low time. thought maybe processing of "if" conditional might make difference swapped high/low , still high signal 3 times longer low signal averaging 11.5us high , 3.7us low above code regardless. is there that's inherently more difficult / time consuming raise vs lower signal? 3x timing difference pretty significant. haven't looked low level programming on uno see how control registers modified there seems wrong. oscilloscopes r fun!   try: void loop() { digitalwrite( jpin, !digitalread(jpin) ); } Arduino Forum > Using Arduino > Pro
