Need help on choosing Sensor board

-

i software engineer , new sensors.i doing experiment mqtt protocol.i want choose sensor board cost effective low budget experiments.i trying out motion detector sensor attached sensor board in http://m2mio.tumblr.com/post/30048662088/a-simple-example-arduino-mqtt-m2m-io arduino uno.i need buy right hardware implementing this.for arduino uni ,can buy arduino uno "http://potentiallabs.com/cart/arduino-uno"? ethernet shield ,can buy "ebay.in/itm/wiznet-w5100-ethernet-shield-for-arduino-uno-mega-with-sd-card-slot-/161523012757?pt=in_computer_components&hash=item259b859495"?should have buy ethernet shield sure when buy arduino uno? there other sensor boards other arduino uno simple configure,support mqtt,cost effective suitable low budget projects?


please not cross-post.  other thread removed.

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem

i'm new member. me pls code: [select] void manhinh1(){                              tempc = analogread(adc);   tempc = tempc * 0.48828125;                                          lcd.setcursor(0, 0); lcd.print("nhiet: ");                                      lcd.setcursor(7, 0); lcd.print(tempc);   lcd.setcursor(13,0); lcd.print((char)223);    lcd.setcursor(14,0); lcd.print("c");   if(max > min){     if (tempc > max)            {digitalwrite(fan, low);           lcd.setcursor(2, 1); lcd.print("lam mat.....");}     else if (tempc < min)           {digitalwrite(hot, low);           lcd.setcursor(2, 1); lcd.print("dang suoi...");           delay(10000); }     else if (tempc > min && tempc < max)           {digitalwrite(fan, high);            digitalwrite(hot, high);            lcd.setcursor(2, 1); lcd.print("on dinh!!");}              }    else if (max < min){    lcd.setcursor(0, 1);

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
