im wanting raspberry pi set when sensor triggered plays sound effect (for party). before go out , buy equipment wondered hard who's not done coding. dont want go out , buy wasted money. understand basics of linux that's it, have seen tutorial (see link below) seems ok. question though work , not need kind of different board adriuno think there called? http://www.linuxvoice.com/raspberry-pi-haunted-house/ advice. yes, linked article work, no, don't need arduino, of no use. raspberrypi

hi, this first project arduino. need attach small cardboard wheel arduino (10 cm) , receive signal every time cardboard moves. the wheel can move in 1 way. potentiometer choice need unlimited rpm. which sensor have use? thank much, daniele hi, daniele. sorry, request not clear me... do want attach piece of cardboard 10 cm wheel? or wheel made of cardboard? 10 cm diameter? attach arduino? and want measure change of state (from stop movement, , movement stop), or rotational speed? rgds, Arduino Forum > Using Arduino > Sensors > Which sensor for a wheel arduino

i using arduino uno project. trying use contact closure trigger uno send charter 9. have figured digital pin 2 needs connected contact trigger response on uno. tx light flashes, nothing happens. brand new @ programming, , have learned whole lot lately, need little guidance figure out. thanks. #include <keypad.h> const byte rows = 1; //four rows const byte cols = 1; //three columns char keys[rows][cols] = {   {'9'}, }; byte rowpins[rows] = {2}; //connect row pinouts of keypad byte colpins[cols] = {6}; //connect column pinouts of keypad keypad keypad = keypad(makekeymap(keys), rowpins, colpins, rows, cols ); void setup() {   serial.begin(9600); }   void loop() {   char key = keypad.getkey();     if (int(key) != 0){     serial.println(key);   } } have opened serial monitor @ output? is set same baud rate? why using matrix key pad code simple contact closure? digital read do. ...

hi, attempting return figures based on file being passed asp page, file csv, split , enter details array. works, have checked, when attempting query database using array having problems, have shown code attempted, no joy. the database connection working have tried , tested it. any appreciated, thanks. <% for = lbound(dzarray) ubound(dzarray) if dzarray(i) <> "" '... error check insure no vbnull value comes through array set rssearch = con.execute("select * myepopbynewagegroups myepopbynewagegroups.datazone = '" & dzarray(i) & "'") if not rs.eof '... error check insure value returned select statement while not rssearch.eof %> <tr> <td><%= rssearch("datazone")%></td> <td><%= rssearch("under 5")%></td> <td><%= rssearch("5-15")%></td> <td><%= rssearch("16-24")%></td> </tr> <% rssear...

hi have rpi switching few devices on , off via relay board. has been working happily time powerful device has habit of breaking whichever relay connected to. 12v/5a peltier heat pump supplied 60w power supply (i know isn't ideal, shortly upgrading 120w). relays rated @ ac250v 10a/dc30v 10a (as seen here: http://www.ebay.co.uk/itm/5v-8-channel- ... 20fd5151b7 ) should able deal load. electronics noob i'm bit puzzled why happening, surely spike transformer when powering on shouldn't enough burn out relay? since have number of 12v devices being operated relays i'm add common 120w 12v supply don't need separate power supply each. peltier cooler utilising , ditch over-worked 60w supply. rpi powered circuit using switching regulator step down 5v. max theoretical load on new circuit ~90w though it's unlikely devices on simultaneously. i'm hoping since 120w supply permanently on reduce spikes occurring thought post here in case i'm making glaring mist...

ciao raga, come si può vedere al link http://www.diariosociale.com ho un problema di spaziatura con il mainbody, cioè mi da anche lo scroll orizzontale. come posso allargarlo così da eliminare lo scroll? io uso il template netweb grazie credo che tu lo abbia sistemato, perché me si vede benissimo e non ha scroller, né orizzontale né verticale....
