ragazzi, più che una collaborazione cerco qualcuno che mi aiuta in un progetto, allora io ho un allevamento di canarini, questo allevamento dovrò spostarlo in una cantina, per fortuna areata, allora quello che vorrei fare è una sorta di centralina per l'illuminazione automatica, visto che le centraline in commercio costano troppo ho pensato al nostro amico arduino, ecco cosa dovrei fare: accensione di due linee di luci, un neon per la luce del giorno ed una lampadina luminescenza x la luce lunare e che simula l'alba e il tramonto. fin qui non ci sarebbero problemi ad impostare l'ora di accensione e spegnimento delle luci, ma quello che cerco io è sincronizzare l'ora con internet e che in automatico accende e spegne le luci in base all'alba di ogni giorno. mi aiutate? partiamo da zero, cioè materiale occorrente e sketch..... grazie. ciao, intanto puoi cercare e leggere quelli che altri hanno fatto per il cotrollo delle serre

hi all, looking , gate, or gate, , comparator chip in dual inline packages raspberry pi project. supply voltage vary between 3 , 5 volts depending on whether using 3 volt battery or 5 volt power supply. of inputs go high @ 5 volts while other inputs go high @ 3 volts. chips must tolerant of these variations. perhaps term "5v-tolerant inputs" applies here. output of , gate needs 3 volts max if supply voltage or inputs @ 5 volts because connected gpio pin on pi. maybe voltage regulator this? chips these qualities exist? if can purchase them? thanks, john hi. logic chips suggest @ 74 series of chips there many variations , might find need there. https://en.wikipedia.org/wiki/7400_series comparator chip bit general depends on want compare. suggest try googling ever want compare , see produces. purchase depends again google find local supplier. suggest update forum profile show location. raspberrypi

hi there, since day, repeating webclient lasts ~16sec untill next loop if have set update interval 1sec. make arduino (mega 2560 r3) update, there correlation this? when use code example "webclientrepeating" last 16 seconds ... hell this? ps: since today have longer cat5 cable (~10m) .. there limitation arduino , cable length? thanks lot answeres!! robin quote from: napster1989 on aug 21, 2016, 07:09 pm i make arduino (mega 2560 r3) update what mean?

a friend running ubuntu 9.10 asked me how enable dvd playback. directed him to link , , told him use these commands: code: sudo apt-get install libdvdread4 sudo /usr/share/doc/libdvdread4/install-css.sh he tried this, , ran problems: i ran problem... entered "apt-get" command above , got nfs-common error. can add/remove programs, update out seeing errors occuring. looked bug on ubuntuforums.org, don't quite see how "fix" installed. there way go date when error didn't occur? or there way have errors evaluated (system check) fixes recommended? i asked him copy of error, , sent me these: code: here copy of listing details of error message while attempting openoffice's data management (like ms access) -------------------------- adding system user `statd' (uid 116) ... adding new user `statd' (uid 116) group `nogroup' ... useradd: cannot lock /etc/passwd; try

hi, basic question... i'd change default foreground/background colours, when click on toolbar's default colour icon (or press d), other black , white. alternatively, i'd able save color , call foreground (or background) colour key-stroke. possible? thanks. i don't think possible change defaults colors. if don't use swatches panel, maybe solution make action sets foreground / background colors, , assign shortcut it.

i've been using bill porter's "easy transfer" library http://www.billporter.info/2011/05/30/easytransfer-arduino-library/ over half duplex rs485 connection , works reliably when there 2 parties talking in master slave fashion. can send thousands of messages , see decoded slave. if add second slave same bus uses different packet format, take turns sending message 1 slave , other, 1 in every 200 or packets fails decoded 1 or other of slaves. the master uses 2 instances of easytransfer object each unique struct created each slave. alternately pipe output same hardware serial port flush @ end of each transmission ensure there no cross contamination of outgoing message bytes. on each slave i'm guessing easytransfer::receivedata() function getting confused 'unwanted' data intended other slave arrives in receive buffer prefix 'wanted' data. sound plausible?

hallo, ich bin neu in diesem forum und bin auch leider noch nicht belesen zum thema arduino aber ich weiß, dass ich damit motoren und servos ansteuern und einstellen kann. das ist auch mein ziel. ich habe eine segmentdrehscheibe (eigenbau ca. 750-1000g) die ich digital steuern möchte. ich habe eine digital-zentrale für meine modellbahn die mit adressen für magnetartikeln wie dem servo arbeitet. ich brauche für den betrieb drei haltepositionen. ist das möglich? ich habe ein paar fragen zu diesem ganzem thema. 1. ist es überhaupt möglich mit dem arduino eine adresse zu erlangen die ich dann meiner zentrale (ldt-system) übermitteln kann und die zentrale automatisch die befehle das arduino schickt? 2. wenn es möglich ist, ist besser? einen dc motor für die steuerung oder eine servo (analog oder digital). benötigt man sonst alles für den aufbau? das sind die schwierigkeiten die ich noch habe ich hoffe ihr könnt mir helfen und mich aufklären. beste grüße dominik

hallo leute, ich suche ein bootloader mit 1 mhz für denn atmega328p. ich sag mal ich vor habe. ich habe mir eine fernbedienung mit dem atmega328p, 16x2 lcd und 2 ir-led's gebaut. dieses läuft im moment mit einem 16 mhz atmega328p. wenn das display deaktiviert ist kein strom bekommt(relais). und der controller im power-down modus ist frisst er immer noch 4,78 ma. das ist zu viel. mal berechnet das wenn ich ein 7805 um auf 5 v zu komme. habe ich dort eine leistung von 0,239 watt die dort abfällt. deswegen würde ich gerne denn controller auf 1 mhz betreiben und mit 2 aa batterien das wäre dann 3 volt der controller läuft von 1.8 v bis 5.5 v bei 4 mhz laut datenblatt. ich kann aber kein 1 mhz bootloader finden. kann mir da einer helfen? lg. jan. hallo, die ca. 5ma zieht der µc aber nicht alleine. im sleep mode mit 5v zieht der auch nur im µa bereich. deine restl. schaltung müßtest du auseinander nehmen und den strom messen.

im having trouble craeting simple calculator can perform 4 basic operations. mistake must  with if-else statements. have 4 conditions addition subtraction multiplication , division, associated 4 letters (a, b, c , d) on keypad in order. if pressed 2 numbers inputed user added if b subtracted , on. (addition) used if , others used else if. , same test (==) all. now, proble, no matter key pressed addition runs. dont know problem might be. thinkin maybe same test cannot ran statements, might right there not meny other tests use [i if (input == 'a') {call addition} , else if (input != a) && (input != a) && (input != a){call subtraction}- == b ==c , == d] still dont understand why cant run same test many times want? i've been trying figure out past 2 days. appreciated. thank in advance, code: [select] #include <keypad.h> #include <liquidcrystal.h> liquidcrystal lcd (7,8,9,10,11,12); int welcometext(){ lcd.begin(16,2);   lcd.clear();   l
