what card size think should use? i have options 8, 16, 32 , 64 gb (i going buy today). thanks answers (fast, please   )! // ooddss depends how data in each logging string. your doing 6x24x7=1008 samples. if divide 8gb capacity can have each string 8 million characters long (a stupid large value). larger cards nice (assuming logger takes them) can used elsewhere or logging more samples , longer durations. if it's purely logging 8gb else bigger better.

ciao tutti, è la prima volta che chiedo aiuto su un forum, e spero di non aver sbagliato qualcosa, in caso l'abbia fatto mi scuso in partenza  :\ alcuni mesi fa mi è stato regalato un kit contenente arduino uno (quindi sono praticamente alle prime armi, anche se avvantaggiato in quanto frequento un itis). essendo che quest'anno ho l'esame di stato ho deciso realizzare un piccolo progetto, e basare su di esso la mia tesina. il progetto cui ho pensato è qualcosa di davvero molto semplice, sarebbe,  bene o male, una simulazione di una serra. vi sono due sensori: un termoresistore e un fotoresistore che inviano valori acquisiti ad arduino, quest'ultimo, tramite un'ethernet shield mette valori online. questo punto una semplicissima applet disegna un grafico con l'andamento dei due sensori. i miei problemi ora sono: 1)come posso "caricare" l'applet sulla pagina web in cui mostro valori dei sensori? 2)ancora non ho acquistato il termoresistore,

hola buenas noches, estoy tratando de controlar dos servos con el ejemplos sweep, pero lo que quiero que que los dos servos se muevan al mismo tiempo, pero lo que sucede es que un servo hace el movimiento marcado y después de acabarlo el otro servo hace el otro movimiento. este es el primer programa que realice #include <servo.h> servo servo1; servo servo2; int pos1=90, pos2=90; void setup() { servo1.attach(2); servo2.attach(3); void loop() {   for(pos1 = 50; pos1 < 130; pos1 += 1)   {   servo1.write(pos1);   delay( ;   }    {     delay(2000);    }   for(pos1 = 130; pos1 > 50; pos1-=1)   {   servo1.write(pos1);   delay( ;   }    {     delay(2000);    } } después de mover un poco logre que los dos servos se movieran al mismo tiempo, pero la velocidad de los servos es muy rápida, me podrían ayudar bajar la velocidad como en el programa de arriba. #include <servo.h> servo servo1; servo servo2; int pos1=90, pos2=90; void setup() { servo1.attach(9); servo2.at

i have project in there 2 buttons: forwards , back. every time forwards button pressed, variable, incremented 1 (i++) , every time button pressed, unincrements 1 (i--). automatically set 0 in setup after each power up. how can use eeprom remember value of int , automatically set variable value every time arduino powered up? look @ eeprom libary. it store bytes. split ints 2 bytes , write them sepratly. read them 2 bytes , combin them using shift operator on significant byte , or least significant byte.

hey guys, first post patient. first time forum poster , first time raspberry pi user. on annual leave work , have heaps of time on hands. had idea of creating backpack raspberry pi media/storage server , internet access point. had idea when on train work. traveling, outdoors , on laptop. because i'm working on laptop swapping out usbs, external hard drives , other peripherals usb 3g modem. after doing research on raspberry pi , others, thought ultra-portability of pi , how isn't electricity cruncher, somehow came backpack server of sorts. thinking of using high capacity power banks (used phones) , combine them (somehow) portable power , stitching (somehow) small solar panels onto front of backpack. thats basic idea power. needing power indicator can tell when need chuck backpack in sun. need way plug power outlet major emergencies (over exaggerating idea). have few ssds laying around i'm not short storage. better use ssds backpack , consume more power if have few

hello, wondering if there anyway connect windows machine (i need windows 7 or vista if have older version please post it) , access machine using windows command prompt. situation have ubuntu server @ home use web,ftp, ssh, bittorrent, server. connect server via ssh , run [this program] , have access command prompt on windows machine on local network. make life alot easier. in advance. steve mitchell lemme think on moment, didn't realize in post.

hi, trying connect 3 hc-sr04 ultrasonic range sensor on pi2. problem pi2 board has 2 5v ports , 1 3.3v port , ultrasonic sensors requires 5v ports. can me out on how possibly use 3.3v third port or maybe "split" 5v port. thanks. manishvaja1 wrote: hi, trying connect 3 hc-sr04 ultrasonic range sensor on pi2. problem pi2 board has 2 5v ports , 1 3.3v port , ultrasonic sensors requires 5v ports. can me out on how possibly use 3.3v third port or maybe "split" 5v port. thanks. i'm afraid you've misunderstood the gpio connector's pinout labelling** - you're referring "2 5v ports , 1 3.3v port" 5v , 3.3v power rail connections. pi's gpio's operate @ 3.3v so, whilst can still provide 5v power sensors, 5v outputs need connected 3 of available gpio's (enabled inputs) through voltage divider, this, perhaps: code: select all sensor 5v out >----------, | 2k2
