sometimes using ic difficult pinout... example, 16-channel led driver ic order of channel pins isn't same order leds lined in. generally create array follows: code: [select] byte ledpin[] = {14, 11, 5, 2, 6, 3, 12, 18, 13, 7, 8, 9, 4, 10, 16, 15}; and when want call light 7th led call upon ledpin[7]. is best/simplest way of remapping pins difficult ics?  can suggest other ways? thanks jonathan depending on how accessing leds, use #define e.g code: [select] #define led7 13 // etc but array method may more appropriate depending if need access leds sequentially btw, ledpin[7]. eighth element in array first element index zero Arduino Forum > Using Arduino > General Electronics > difficult IC pinouts arduino

salve tutti. sto progettando un prototipo di casa domotica basata su arduino, tramite l' interfaccia ethernet shield collego arduino alla rete locale, e con una piccola interfaccia html attivo o disattivo pin di uscita di arduino collegate degli attuatori. ho sviluppato due sketch, uno per il controllo di un sensore di temperatura e sei attuatori digitali ed un secondo sketch per il controllo di due servomotori. due sketch separati funzionano alla perfezione, ma quando vado ad unirli in un unico sketch  il caricamento su arduino viene completato senza problemi, ma all' apertura dell' indirizzo interno di arduino (192.168.1.123) mi compare il messaggio di pagina non disponibile. da cosa può essere causato ciò? io pensavo ad un errore causato dallo sketch (in particolar modo la parte html) troppo pesante, ma potrebbe anche essere un mio errore.   nel caso in cui fosse proprio la pesanezza  il problema, come posso risolvere? vi lascio in allegato l...

hi guys, got question on whether idea and/or feasible project. i'm thinking of getting arduino ethernet, have plugged router , draw power ethernet cable. then somehow tap home alarm trigger, when alarm kicks in, run code. for i'm planning send email myself starter, later i'm thinking of sending commands cameras , have them start recording stuff... i'm pretty sure do-able, can tell me whether using arduino ethernet this? know how make trigger? or tap signal wire io input (maybe need resistor triggering input right?) i'm new arduino, not new programming. thanks! i'm no expert on ethernet side, on connection alarm should perhaps consider opto-isolator which make sure alarm signal electrically separated arduino. output isolator normal digital input. code looping forever, reading pin on each pass, , if it's (say) low, kick off appropriate part of code.

hello everyone, wondering if has bought arduino bt device me out. im thinking buying build portable device measure uterus' muscle movements (electrohisteromyography) during pregnancy. my question is, (i have never worked arduino), arduino bt come usb port incorporated in device? can connect shield or allow save data in usb device patient , doctors can access them? bluetooth , usb data transfer approach project, can have modern mobile application side , old school usb disk in pc too. please me thanks! sry if question sounds kind of weird, it's first time i'm using these devices.

so, i'm pretty new arduino. what trying find code use 1 button cycle through 5-10 different vibration options. press 1 = 50 50 press 2 = 100 100 etc... i wanted able use 2 buttons select , down , happy one. have gathered far should use hardware debounce , interrupts in sketch, don't know how. can point me in direction of begginer understand? thank you. quote what have gathered far should use hardware debounce , interrupts in sketch, don't know how. most wrong in both respects, need explain quote press 1 = 50 50 press 2 = 100 100 etc. means.

我现在想利用joomla做一个自己的中文网站，想请教大虾如何系统的建立一个中文网站。 1。首先请看我的实验品：  http://www.livingchinatown.com/joomla 2.  我的问题如下： -- 是用英语版的joomla  加中文软件包做的，但是其中，象 main menu 等这些我不能修改成中文。 -- 目前我安装的路径是http://www.livingchinatown.com/joomla/ ，我是否可以修改路径，而无须重装软件？ -- 我想把joomla和discuz的论坛结合，不知道如何实现。   盼能帮我解答。谢谢。 1、mainmenu 这种标题属于“模块名称”而不是“菜单项目”，因此在菜单上无法修改，你必须进入”modules -> site modules -> main menu“，然后将其名称改为中文”主菜单“，点击"save" 即可。如果不想显示，则选择 hide 即可。 2、可以更换路径，我的网站就曾经这么做过。但是要注意，要将所有涉及到路径的设置修改过来：第一个就是 configuration.php ，如果安装了 jd-wordpress 来做 blog，那就更麻烦，必须进入数据库手动修改。 3、joomla 与 discuz 论坛的结合 autoit 已经成功，可以向他请教。不过，我觉得似乎 smf 论坛也不错，可以考虑一下。我的网站 joomla之门 有桥接 smf 的教程.
