ciao tutti sto iniziando muovere primi passi con arduino, e la prima applicazione che vorrei realizzare riguarda il controllo di alcuni paramentri climatici di una serra che ho costruito. tale serra ospita delle piante carnivore (le quali, per chi non lo sapesse, hanno bisogno sempre di 2 / 4 cm di acqua distillata nel sottovaso) ora, parametri che vorrei monitorare sono: temperatura ed umidità interna, temperatura ed umidità esterna (tramite dht11, che già possiedo), il livello di acqua di tre vasche da idrocoltura (con tre sensori ad ultrasuoni, che mi dovrebbero arrivare in settimana), poi la velocità del vento (con un anemometro che ho costruito io, tramite sensore reed - ovviamente montato sul tetto della serra e non dentro! ) e mi piacerebbe che arduino mi desse in uscita dati su un display lcd con due pulsanti per selezionare diversi tipi di dati. la questione della pulsantiera l'ho risolta senza occupare alcun pin digitale, ma solo uno di quelli analogici (ho col

ciao ancora tutti! dopo primi esperimenti di ieri ho riflettuto sull'alimentazione dei miei servi e della mia arduino mentre osservavo il porta batterie da 4 posti (aa) e il mio servo che si muoveva veloce e preciso su e giu''. chissaì quanta benzina sta succhiando! ho letto il datasheet dei miei servi (futaba s3003) e ho visto che succhiano 8ma in idle 6v (quindi riposo) purtroppo posso solo speculare su quanti ampere consumano sotto sforzo. possono "sollevare" fino 4.1kg/cm (sempre 6v) ma diciamo che nel mio progetto arriveranno spingere al massimo un terzo di questi 4.1kg. quindi diciamo che nel loro massimo sforzo che sara' di circa 1.3kg assorbiranno 15/20 ma? (diciamo 18ma) considerando che saranno 12 servi, avro' una richiesta di circa 216ma complessiva se tutti si trovassero sotto massimo sforzo. naturalmente, questo punto, perde totalmente di logica l'idea di sfruttare pin della mia mega2560, ricordo che limiti di ma dei singoli pin

i created stopwatch using , arduino uno, lcd display, start button, , reset button. code uses millis() function current number of milliseconds, little math, , displays minutes:seconds:hundredths. when arduino plugged usb port on computer, accuracy (when checked racing stopwatch) accurate. when plug 9v battery arduino, homemade stopwatch accurate. so... wanted make more permanent. built standalone arduino using atmega328, 20 mhz quart crystal, 9v-to-5v step-up/step-down regulator pololu, , foot switch start/stop stopwatch (this why built homemade stopwatch begin -- foot switch operated stopwatch). soldered board. standalone stopwatch runs faster should. example, when racing stopwatch says 20 seconds, homemade stopwatch says 25 seconds. does have ideas why homemade stopwatch running fast? ideas how can fix it? thanks! quote does have ideas why homemade stopwatch running fast? ideas how can fix it? an arduino clocked 16mhz. if built custom board 20mhz clock

for past 3 days have been trying decode air condition's remote.. 1stly remote not @ recognized neither irremote nor irlib libraries.. i started  googling on how decode , air condition's remote.. i came of aircon remotes sends long commands.. from below thread came know commands sent twice. http://forum.arduino.cc/index.php?topic=226419.15 on thread's 16th post analysir guesses "this may increase chance of signal or basic error checking" analysir has been doing great job , has contributed effort understand , decode signal of on/off button precious application.. my views found out today suddenly 1. aircon remotes sends 2 different values on , off 2. temp , temp down buttons sends different values different temperatures.. 3.the air swing , fan speed sends different values each state.. so come know of buttons sends multiple values. 4. important part... i found these multiple value buttons not sends value of own, checks states of other buttons (pwr, temp, swi

this funny.  logged in admin not allowed save changes general configuration file.  however if root open config file can edit manually , save fine.  somehow admin user don't have same rights root, surprising admin can't change con fig file.    any explanation?  if @ top of forum see post called: please read me: file ownership issues http://forum.joomla.org/index.php/topic,51041.0.html basically it's owns file , permissions set on file , attempting change file. so when stuff in joomla admin, web server process "person" doing changes , that's different root user. either have chown config file web server process user or chmod world writable. can change via admin global config.

bonjour, je voudrais savoir pourquoi mon programme ne fonctionne pas, les erreurs qu'elles sont elles? car je pouvais rajouter à ma bibliothéque le irremote.h mais quand je le faisais cela me méttait des erreurs comme quoi des variables n'étaient pas définits. c'est pour cela que j'ai directement rajouté tous le programme et plus le programme que je devais écrire. donc maintenat les variablent sont bien définient mais les erreurs ont bien changées. le programme etait celui la: /*    reception infrarouge */ #include <irremote.h> int broche_reception = 11; // broche 11 utilisée irrecv reception_ir(broche_reception); // crée une instance decode_results decode_ir; // stockage données reçues void setup() {   serial.begin(9600);   reception_ir.enableirin(); // démarre la réception } void loop() {   if (reception_ir.decode(&decode_ir))   {     serial.println(decode_ir.value, hex);     reception_ir.resume(); // reçoit le prochain code   } } les erreurs sont

how people go determining position of autonomous ground robot (relative charging station)? robot in question roam around house building map of walls , furniture, , maybe useful once has information. imagine it's possible accelerometer, there sensor better suited task? it's not possible accelerometer. if try calculate position based on acceleration readings on time you'll find off course within few seconds. accelerometers not precise enough. indoors best chance using infrared beacons. if want find charging station rover can bump around until sees beacon , home in on it. if create multiple beacons , have each emit specific (remote control) signal rover can triangulation. an arduino isn't right board mapping. not enough memory. if use raspberry pi can use upward facing camera , fiducials on ceiling triangulate position , quite accurately (google "reactivision").
