i have seen in net different tutorials stream camera (h264, logitech webcam, motion...) don't have camera , have start anew wanted advice know way better, before buying hardware , starting configure it. want perform 2 things: raspberry clicks picture every minute of home , uploads picture dropbox, or other service. if possible, @ same time, raspberry streams video can watch home live mozilla. usual, cheaper better you use raspi camera - stream video minute, stop, take picture, stream video minute etc. hope mod code @ point can snapshot whilst videoing means run 1 app without having change video capture apps. raspberrypi

good evening, can has experience various microcontrollers share thoughts on brand types of purposes? i've heard of things arm have not used mcus before. curious find out more , see if worth changing current atmega328 arm mcu. thank much. honestly, less documented , stay avr series unless have reason change.

ciao tutti sono andrea studente di ingegneria informatica e di recente ho conosciuto l'arduino e devo dire che è molto interessante. vi descrivo cosa vorrei realizzare: nella mia abitazione ho una vasca per l'acqua con una pompa che viene azionata nel momento in cui manca l'acqua. vorrei realizzare un qualcosa che mi indichi il livello dell'acqua che posso consultare da dentro casa dato che la vasca si trova esternamente. la mia idea: pensavo di programmare un atmega da far funzionare senza board arduino in cui collego un sensore ad ultrasuoni che monto nel coperchio della vasca in modo che legge il livello dell'acqua e lo manda in qualche modo dentro casa. dentro casa volevo collegare l'arduino 2009 tramite ethernet shield alla lan, gli carico un piccolo server che mi legge le informazioni che gli manda l'atmega messo nella vasca e prepara una pagina web ad hoc. il problema: come far comunicare l'atmega nella vasca con l'arduino de...

hi guys, i'm having problems sparkfun serlcd. sometimes (i don't why) when power arduino , lcd strange symbols on screen "xx||xx" . happens it's annoying. if turn on , off power few times screen shows correct text. at beginning used pin 0 rx , thought problem changed pin 3. worked few days problems started again. i'm using serlcd library , connected. seems there problem of synchronization between arduino , lcd don't know how solve it. thank  you! what baud rate running serlcd at?

i've allready got little standalone control panel running, controlling 6 outputs , showing txt in 16x2 lcd. (based on atmega 328 chip) now come idea of controlling backlight in software, , got working program running on uno. it controls led backligt pwm pin 10. now when inplement in stand alone project, need hook aref pin vcc , aref gnd pin gnd ? or needed when reading anlog values ? thanks (hopefully) upcomming , sorry if dumb question. avcc (20) +5v. aref (21) not connected might put 0.1 uf gnd. agnd (22) gnd.

hey guys, not sure if popular subject have tried looking through google "arduino read string serial convert integer" because issue having number entered in serial user , having character/string converted actual number. code having problems shown below code: [select] char c = serial.read();   readstring.indexof(c); //i have tried using readstring.concat(c) append int n; n = atoi(readstring); //convert string number the error " error: cannot convert 'string' 'const char*' argument '1' 'int atoi(const char*)' ". so, unsure of doing wrong. did try code: [select] char *c = serial.read(); , arduino did not either. appreciated. http://arduino.cc/en/reference/stringtochararray ?
