recently purchased linknode r4 linksprite. of unfamiliar device esp8266 4 5v/125vac10a/250vac10a relays 5vdc in. unfortunately none of other gpio pins broken out. have r4 stuffed in gangbox own dedicated 4a psu. it's relays each connected single 125vac plug socket. power provided through standard 3 prong recepticle accepts standard 3 prong pc power cable. both dc psu , 125vac mains individually switched allow debugging , programming r4 without having hot mains running through relays. currently r4 controlled linknode app interfaces cloud. works quite reason project emulate belkin wemo smart switch , control through echo dot. flashing firmware later today ftdi adapter has arrived. experimented using arduino nano clone(ch340 usb serial) connected esp201 communication handled software serial @ 115200 bauds. esp201 shipped @ firmware thought might idea see if program arduino first test rather risk bricking r4. @ rate had inconsistent results. @ times commands work, @ other tim...

is there joomla groups or websites, paid or not, users here recommend? please send me instant message posting links websites against rules here if promoting anything. i part of joomla community. can when needed , if have time (i'm director of marketing), need more things, better resources related joomla. have been able use information site degree, i'm getting more serious joomla, part of group offers better resources. free, or donation based of course better, paid service isn't out of question. i'm running joomla 1.0.12 , 1.5rc2. tried 1.5rc3 , crashed server i'm still trying figure out. i can't imagine find better resources right here on joomla forums extensions directory @ fngertips!  Board index Joomla!

hi, example if have master , slave. master request bytes slave, slave send required bytes over. therefore, question which of arduino board should connected computer? right because master printing serial com should connected computer , slave powered master? connect whichever 1 want send data computer computer.  there nothing in question implies either 1 better other.  either 1 talking serial computer.  matter both communicating computer on serial.  Arduino Forum > Using Arduino > Project Guidance > i2C Question on connection of board arduino

hello, i'm hoping can tell me i'm doing wrong here i've banged head against wall on weeks. as exercise in learning arduino , esp8266 trying build wifi enabled cat toy. concept have this: - 2 servos (x , y) - laser pointer (5v) - esp8266 - atmega326pu the idea this: have esp8266 programmed connect wifi , run micro http server. when visit http://ipaddress/power/on turns gpio2 on esp8266 on, , when visit http://ipaddress/power/off turns off. on atmega side, sketch inits servos, , monitors esp8266's gpio 2 pin go high. once does, runs it's program turn on laser (attached atmega gpio) , start moving servos around. i built out on breadboard , worked. problem put prototype board circuit , when run it, runs fine until try turn servos on. might move them once or twice before apparently freezing , no longer accepting commands. have status led blinks in different patterns in different status can monitor chip , seems fine until turn on servos @ point led freezes high ...

hello, i upgraded avr library suggested today , arduino script not working anymore. have systematic error when opening file on sd card (sd.open) while running fine since 3 years. havne't found way know avr library realease. will full upgrade on 1.8.0 ? i have pc older version , check, wondering if has experienced such issue. using arduino uno , ide 1.6.7 thanks please post either error msg's or decent screen shots. use code tags ( </> ) post error msg. please.

hi all, i've finished writing 2-byte / 4-byte serial io control protocol.  been testing , debugging on arduino mega.  plan implement xbee @ serial control project although works 2-serially connected arduiono's.  i'd highly suggest using mega ( due multiple ports allowing debug messages ).  anyways, wanted share in case else looking same thing.  fresh , may still have bugs - please mention them if find them. below quick code snippet of attached code. (update)  i've uploaded https://github.com/tgit23/peerioserialcontrol library code: [select] /**************************************************************************************************     arduino sketch peer i/o control of arduino boards through serial.   - sketch uses byte level protocol; not serial monitor text control     usage:   - connect serial communications between multiple arduino's   - set 'arduinoid' variable (line #63) ...

hola no soy capaz de programar el lylipad arduino ni con programador ftdi y tampoco usando el arduino uno como programador yo creo que sigo bien los pasos  1º selecciono lylipad arduino 328 2º el com x 3º aqui es donde dudo pero e probado varias opciones   arduino isp   o arduino isp ? o alguna otra de las opciones este es el error avrdude: stk500_getsync(): not in sync: resp=0x00 pues la impotencia ya es total y ya no se de donde sacar informacion para programar un lilypad hola pues ya e resuelto el problema en el ide arduino no hay que seleccionar como targeta el lilypad arduino  hay que seleccionar arduino mini w /atmega 328  cosa rara pero mi me funcioina ahora me gustaria saber como agregar mas led al sketch blik salu2 Arduino Forum > International > Español > Software (Moderators: surbyte, Hector_A)...
