Web controlled relays malfunction when carrying load

i have fitted arduino ethernet shield , 4 single relays, can control 240v. i trying make web interface, control 240v devices in house. post code below. when testing nothing connected relays, works charm. can press button in web browser, digital state shifts accordingly. but whenever connect relay, arduino crashes, , web server stops. i can control other relays flawlessly, when choose relay carrying load - crash! hope can me? code: [select] #include <spi.h> #include <ethernet.h> string commandstring = string(30); byte mac[] = {   0xde, 0xad, 0xbe, 0xef, 0xfe, 0xed };   string portnames[10] = {"","","","","","","port 6","port 7","airport express","forstaerker stuen"}; // initialize ethernet server library ethernetserver server = ethernetserver(80); void setup() {   // set ports   ( int port = 6; port <= 9; port++ ) {             pinmode(port,output);   }   // start

16x2 LCD nearly works - but has a few strange characters. Why???

hi everyone, i beginner please excuse lack of knowledge how lcd's work (let alone i2c lcd's). project aim: display serial number of rfid tag onto 16x2 i2c lcd. hardware: 1) arduino uno smd r2; 2) innovations id-20la rfid reader , 1 rfid card (to wave in front of it); 3) 16x2 serial clear victory 1602-1 lcd module i2c backpack (gy-iiclcd).  both cheap off ebay; software: 1) arduino ide 1.0.5 (and use serial monitor display rfid card number); 2) new liquidcrystal library (by f malpartida). what happens: when wave rfid card in front of rfid reader, beeps indicate successful read, rfid card number displayed via serial monitor correctly, when appears on lcd screen has 1 x strange character before it, , 3 strange characters after it.  the actual rfid number in between strange characters correct however. my code: as new, found 2 pieces of code , put them try , achieve aim - did not write of it.  i assume there problem in way have combined 2 sketches.  code below: code: [sele

ArduIMU Voltage and time problem

hi guys, know not strictly arduino product figured if knew how work out on here. bought arduimu , programming onto it, wondering know if can run board off 3.3v battery? https://www.sparkfun.com/products/11055 . checking through page , seems suggest board says vin 6-12v. want run arduino accelorometer values, mpu6000 , atmega guess? successful @ programming onto 3.3v ftdi board? also know time appears int value? i'm not sure if utc or similar that? , wondering if knew how accurate time be? i'm looking @ obtaining times in tenth of second. that board uses 5v atmega328, else using 3.3v. the atmega328 @ 16mhz running @ 3.3v outside specifications, run. what 3.3v battery ? li-ion battery of 3.0 4.2 v ? when supply 3.3v power plug of board, voltage regulator lower voltage some, , atmega328 might not run. i think board run 4.0v , up, maybe 3.6v, , perhaps 3.3v lucky.

Problema Interrupt + Serial.println

salve ragazzi!!!! stavo sviluppando un progetto abbastanza semplice ( una versione del cat feeder ormai famoso sul sito) con degli interrupt. in pratica un sensore luminoso genera un interrupt quando c'è molta luce ( e la resistenza ldr si abbassa, tipo falling) , e questo evento aziona un servomotore che ,dalla posizione di riposo impostata nel loop, si apre per 5 secondi e poi si richiude. fino qui tutto bene. poi ho cominciato "ricamare il software", e ho inserito qualche serial.print per tenere d'occhio alcune cose, ad esempio, quante volte era stato azionato il meccanismo. ( gli interrupt vengono disabilitati dopo 5 eventi) . ebbene, da quando ho inserito println , il codice si blocca spesso e volentieri. nella console vengono visualizzate scritte come "evento rilevato: pasto numero 1" "evento rilevato: pasto numero 2" "ev" e poi si blocca. non riesco capire perchè, e la cosa è molto fastidiosa. qualcuno può darmi una mano?

hello, i tested transmit data serve http. tested 4 hours maybe , posted request. data traffic sim card time 300 mb ! i sent body content "xxxxxxx,dd.dddddd,x,d.ddddddd" , response "xdd,d.dx". know header data weight, extreme data traffic small data. is problem sapr or inithttp? call commands (down) in loop every 30-60s. code: [select] //simply code without delay , reading buffer                gprs_com.println("at+cgatt?"); gprs_com.println("at+sapbr=3,1,\"contype\",\"gprs\""); gprs_com.println("at+sapbr=3,1,\"apn\",\"internet.t-mobile.cz\""); gprs_com.println("at+sapbr=1,1"); gprs_com.println("at+httpinit"); gprs_com.println("at+httppara=\"url\",\""+string(device_api)+"/incominghandler.ashx?data=" + data + "\""); gprs_com.println("at+httpaction=0"); gprs_com.println("at+http

Pin 7 Always on - Raspberry Pi Forums

i have led hooked pin 7 (gpio4) on raspberry pi 1 b. led works fine, barely on. on of time, regardless of set pin to. also, when run code: select all gpio read 7 returns 0. not sure if other pins same way. there hope raspberry or need new one? advice appreciated. a few things remember; leds polarized, include resistor when using leds, double/triple check connections. going 3v3->led+resistor->gpio(active low) or gpio->led+resistor->gnd(active high)? circuit diagram or textual explanation nice. raspberrypi

Importing Topics

i have created new robohelp project , have old robohelp project. need export topics old robohelp project new robohelp project. old project contains many topics not need in old project. topics need contained in several books. is there simpler way export topics need other conditionally-tagging topics don't need , creating .chm file import new project? amanda how many files need import new project? can import each html topic source file directly new project. go file > import > html file, , choose topic old project. if have lot of topics import, may not fastest way, doesn't involve "exporting" topics. --ben More discussions in RoboHelp HTML adobe

Serial - EEPROM

i need read eeprom, sending position read serial monitor eg       value = eeprom.read (sent serial monitor); the problem data sent received ascii given ej:  1 = 49 reads instructions eeprom.read position 49 , not 1 want. use 1 subtracts ej: num = value - 48 works positions 0 9. i appreciate help, thank ..! quote use 1 subtracts ej: num = value - 48 works positions 0 9. what other digits plan on sending? if want multi-digit numbers, combine individual digits in meaningful way. done collecting data in null-terminated char array, until end of packet marker arrives, , calling atoi() array. if can't that, use serial.parseint().

hola soy nuevo en esto de arduino y investigado mucho y probado tambien pero no obtenido buenos resultados ya que los sketch que probado se demora mucho tiempo en calcular la frecuencia la idea es que bajo los  100 hertz (onda cuadrada) mantenga un led apagado y sobre estos lo mantenga encendido  obviamente en el menor tiempo posible espero que me puedan ayudar saludos y gracias de antemano . buscando por hay encontre este frecuenciometro pero veo que contiene algunos delay   se podra modificar este codigo para lo que necesito aqui dejo el codigo saludos code: [select] /* frequency counter arduino sketch by: jim lindblom sparkfun electronics license: beerware isn't accurate frequency counter, it's simple to program , understand, , works in pinch. i've tested to accurate @ least 96% (usually around 99.5%). should able measure frequencies 6.5mhz(8mhz optimally) circuit: powered @ 5v (5v lcd), arduino running @ 16mhz d2 - rs (lcd) d3
