Arduino e 3 led IR

-

ciao tutti  :)
sto usando la libreria irremote ma si può controllare solo un led ir sul pin 3 (o sul  9 cambiando impostazioni), visto che devo controllare più led (non contemporaneamente) ho fatto questo schema:



il stn2222 e il led (trasparente) l'ho recuperati da un telecomando.
2 led li ho  presi da un altro telecomando (colore violaceo)
i c536n e il a608n li ho presi dalla scheda di una stampante.

penso sia tutto giusto ma vorrei una conferma prima di bruciare qualcosa  :smiley-roll-sweat:

mi sono appena accorto che usando un pnp sul pin 3 avrei il segnale al contrario  :smiley-roll-blue:

i'm looking way roaming = 0 in lan, can't figure how it... i'm looking in hostpd.conf , here 802.11r / iapp etc... has managed roaming = 0 system? got lan multiple wired pi ap running in bridge mode eth0 , wlan0. separated ssid, , time change 1 other long. please advice me, thanks. br i have not tried setting pi access point wireless admin , note seem saying each pi has separate ssid. mean device needs learn every pi's ssids , not roam new pi until connection previous 1 gets bad, @ point device re authenticate next pi, causing drop , reconnect, not roam. wireless roaming want use extended service set (ess) , have each pi using exact same ssid, client doesn't need reauth or , can associate same ssid different pi. of course want make sure each pi set different wireless channel don't interfere each other. sorry can't offer more point in right direction. raspberrypi

hi, we looking redo of project in arduino. advice on components use, , trouble might run in to. project goes follows: we want unlock car smartphone (eg iphone), in car, there box containig arduino chip, connected unlock functionality of car. want use bluetooth communicate car. want keep cheap possible. quote what basic arduino board should use? the board needs relays to activate electronics , should able connect bluetooth module (and battery). should have capacity run encryption algorithm security.. quote what bluetooth module should use? the module should able connect board. consume lot of battery? have intuitive interface towards iphone , android? bluetooth recommended or have security issues? i appreciate input community, first arduino project :-) regards, mathi quote from: mathi on jun 24, 2013, 06:12 pm it should have capacity run encryption algorithm security.. in view requirement factor of hundred more difficult rest of project put together. design...
