ciao tutti. utilizzanod un arduino mega, mi sono costruito un irrigatore molto semplice, che comanda una pompa 12v o un'elettrovalvola in base dei comandi arrivati sulla seriale, oppure in base ad orari impostati su un rtc. esegue un logging periodico della temperatura su sd card e fa un po' di beep quando viene avviato o fermato (anche da comando manuale). fin qui tutto ok, tranne che adesso, vorrei usare il mio arduino per altri progetti, ma l'irrigatore mi serve. mi piacerebbe passare dal prototipo ad un pezzo hw con solo quello che mi serve, micro, quarzo.... vorrei qualche suggerimento su come gestire la cosa, visto che di hw ho poca esperienza. quali pezzi mi servono, quali accorgimenti devo avere... io pensavo di usare una piastra millefori con micro zoccolato... suggerimenti? grazie se fosse una uno sarebbe semplice, ma con una mega è decisamente più complicato. la mega ha più porte e più memoria e se forse è possibile ridurre il numer...

i joined 2 minutes ago. learn alot more hardware options, standards/conventions of understanding different hardware models mean, release cadences of oses usable on raspberry pi devices , can go start of research. able learn storage options, , power options. example, can cigarette lighter adapter power raspberry pi? or stuck sacrificing usb port in vehicle if wanted place device on dash , use dashcam; example? thank in advance. all of these subjects have been covered multiple times on multiple websites, including here. have large documentation section. google find answers questions quite rapidly. raspberrypi

hi there, trying troubleshoot board design touch sensitive toy developing based on atmega8 internal osc configuration. uses 10 super bright white leds sink 20ma each, of them connected respective 68r resistor , in series on pin 8. have 8ohm 0.3w speaker connected 100r resistor bc337 (single transistor amp configuration, other leads go +5v , gnd) pin 9. capacitive sensor connected pins 4 , 2 10m ohm resistor inbetween same in capsense library example. code works fine, , thought 1a usb adaptor fine this, , little, project seems unstable , saw spark on power outlet. am frying electrons here? should split leds several pins or not me @ all? what should for, mean, kind of question should ask google can figure out what's heppening? thank's bunch, keep hacking stuff. a digital output pin can source/sink @ 40ma, pins not more 200ma.

currently laptop connected via ethernet our router. got phone has wifi , i'd avoid expensive carrier charges connecting via wifi laptop's internet connection. found a page in community documentation, instructions written feisty. i'm wondering if there different or more simple way in karmic. thanks! your phone wifi router? or router wifi enabled?

if you're fan of electronics me find annoying on lack of hardware serial ports on modern devices. many modules wifi esp8266 , bluetooth hc-06 available peanuts each require uart based serial peripheral on controller work effectively. in fact huge range of external electronics can added system via serial uart connection: gps, gsm (mobile phone), rfid, rs232, lin, ethernet, zigbee, modbus, dmx, 4d systems graphical lcds name few more. most modern microcontrollers , devices raspberry pi have @ least 1 serial uart peripheral can lot these devices. , need combine several communications style modules single design. recent project undertook mobile alarm system used bluetooth proximity arm / disarm system, gps track location, accelerometer track movement , gsm based sms messages inform owner item is. the arduino mega 2560 offers 4 serial uart peripherals if not enough or need more affordable mass production. move different chip may mean rewriting entire code there easier way? the...
