Connecting Several Ultrasonic Sensors to One Arduino Over a Long Distance

-

i have arduino uno r3 need connect several (3-4) srf05 ultrasonic sensors to, tmp36 temperature sensor, across room. wire length needs 10-20 meters, though it'll differ each one. how can accomplished on small budget?

the ultrasonic sensors should no problem @ on 10-20m of cable. glitches cable long pick lots of interferences, such spike every time fridge motor switches on. need apply filtering, such using value if same reading 10 times in row, within +/- tolerance. should put protection diodes close arduino spikes can never go lower 0v or higher 5v.

the temperature sensor different. interference picked on long cables distort analog voltage , can't 'filter' that. can put arduino in same place thermometer , run long wires digital sensors?

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
