Looking for advice on what cable connector to use

i have bunch of sensors on 1 end , long distance till arduino. these sensors prone break want able make them "plug , play"-ish no soldering required (i won't maintaining particular install). so need connectors fit these requirements (or @ least of them): * easy install (soldering ok, i'd rather not have buy cripmer) * don't need particularly durable; if last 20 uses that's fine. * veroboard friendly prototyping that. * big plus if can bought @ sparkfun have big order need make soon. * big plus if cheap! any appreciated. why not use screw terminals? https://www.sparkfun.com/products/10571 Arduino Forum > Using Arduino > Project Guidance > Looking for advice on what cable connector to use arduino

au premier abord le nouveau raspberry semble pas mal . c'est sur qu'a 35 euros il est intéressant . le problème c'est que je serai assez intéresser par l'achat d'un raspberry b 512 mo pour lui greffer ce module x100 . ce module m’intéresse pour l'horloge intégrée ,le fait qu'il transforme le hdmi en vga et il dispose en plus d'un port série . sauf que ce module x100 n'est pas revu pour le model b+ . reste donc trouver le magasin qui le modèle b ancien et le x100 .dx.com faisait un lot sympa avec un pi asiatique sauf que je suis pour l'instant en litige sur une commande non reçue . pour l'instant le vieux b 256 mo me suffit . je veux bien investir 70 euros sur du pi mais je tiens cette horloge et cette sortie en vga . bonjour, ptitpaj wrote: sauf que je suis pour l'instant en litige sur une commande non reçue utilise le compte de ta femme, ton pote ou ton chien a+ raspberrypi

!JoomlaComment funkar inte - Joomla! Forum - community, help and support

jag har tidigare använt en äldre version (än 2.33) och det slutade plötsligt att fungera. testade därför att uppgradera (bÃ¥de joomla och !jommlacomment) men fÃ¥ fortfarande ett meddelande att behörighet saknas om jag inte är inloggad. jag vill att alla besökare till sajten skall kunna kommentera uta att vara registrerade användare. jag har satt allt jag kunnat till "public" ooch har därmed slut pÃ¥ egna ideèr vad som är fel. nÃ¥gon annan som har haft detta problem, och dessutom löst det?  ingen?? ok, ställer om frÃ¥gan lite mer allmänt hÃ¥llen; vad kan orsaka att vissa saker inte är Ã¥tkomliga för "public" trots att alla inställningar (som jag hittar) är satta till "public"?

Toggle Switching ~ Display clock

hello, my newest challenge myself make clock display time/date/month/year/sec etc.... question i'm wanting know, have 1 of these toggle switches http://forum.arduino.cc/index.php/topic,15642.0.html, is possible connect these arduino perform increments , decrements clock, example, if(pin2 high) months++; // although bad example, using demonstrate how want toggles act if(pin3 high) months--; ive coded type of thing before on atmega32, using avr, better idea me avr studio , code way? jtag mkii? in summary : clock displays day/time/month, toggles increment , decrement values set time. (4 toggles switches, both way) it's possible if type of switch returns middle. if normal on/off toggle, won't work right.

data storage SD card or HDD? - Raspberry Pi Forums

hi guys, have lot of instructions (1000s write cycles/per day) rpi storage sd card. think if should use storage sd card or hdd. heard there limited write cycles sd card (approx. 100,000). , when power goes down in moment when rpi writing data sd card, can corrupt sd card - maybe hdd more resistant failure. right? what's opinion? ymmv, if writing lots , putting hd in mix can in long run , , usb hub + usb hd adapter , hd , power can made quite small.... sort of application looking @ ? can add battery backup device if needed raspberrypi

Thread: Converting video to iso?

i have added "memup" 1tb box audio setup can add photos, music, films , home dv , have them in 1 place , show them on pc or dvd projector. box comes formatted fat32 , don't think can change without upsetting system. have use ntfs , box refuses formats (including avi) except iso ok. question is, how change avi , other formats iso. use ubunto time though not technical command line, unless simple, not option. an iso otherwise known image file. if you're familiar zip file, it's similar concept. storing of files within iso. more technically, iso file meant copy of disc. i'm not familiar system referring to. digital media player? iso file have resemble dvd video? or can data dvd?

Interfacing an Arduino MEGA 2560 with LabVIEW

hello everyone, i hope posting in correct forum , if not, please move appropriate one. project working on construct circuit made of following parts: five irf9540 p-type mosfets (represented m1, 3, 5, 7, 9 in circuit diagram) five irf510 n-type mosfets (represented m2, 4, 6, 8, 10 in circuit diagram) five d1n4006 diodes five 1k ? resistors five 280 ? resistors r591763400 (rf switch radiall) the rf switch represented l1, l2, l3, l4, , l5, correspond following pins on switch respectively: 1, 2, 4, 5, , r (which resets switch). this circuit receive 5 volts output arduino mega 2560 (which represented v2 function generator in circuit can see provided attachment), , need have labview communicate arduino sending instructions arduino outputs 5 volts pins 1, 2, 4, 5, , r whenever needed person controlling interface. have labview 2009 installed on computer, along labview interface arduino (lifa) v2.2.0.79 obtained via vi package manager. i've been going through lot of tutorials inte...
