Three serial channels on Arduino UNO

-

i working on rfid reader communicate serially arduino uno on pin (2 , 3).

also, displaying information on serial lcd connected pins (10, , 11)

i save information @ sd card using arduino wifi shield, possible?

you need move lcd pins.
sd cards use spi interface - sck-miso-mosi on 13-12-11, , slave select on 10 usually, or 4. if 4, 10 needs output arduino spi master, if not being used spi.

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
