Program Multiple Sensors on Arduino Mega

-

hi,


i new on concept of arduino.  part of project need make atmospheric , vehicle data acquisition  using followings components:
  • arduino mega
  • barometric sensor (bme280)
  • light sensor (tsl2561)
  • gps
  • accelerometer adxl377
  • micro sd


i perform codes separate , components work correctly, when merge codes in 1 program, system not work.  1 of error codes in different languages. there suggestions able join codes, or can me this?

thanks , happy holidays! :)

quote
one of error codes in different languages.
nonsense. if each sketch worked individually, in c++.

quote
are there suggestions able join codes
yes. don't use same pins different purposes. don't use strings.

quote
something can me this?
we need see attempt combine them, , need know issue is.

links hardware using interesting. names not really.

a schematic showing how connected essential.

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...
