ADXL345 doesn't work

-

i trying data adxl345 doesn't work. tried i2c , spi connections , both failed. here how connect adxl345 arduino uno:

i2c:
 
 adxl345  ->   arduino

     vcc    ->     5v or 3.3v (adxl345 has regulator doesn't matter)
     gnd    ->     gnd
     scl     ->    scl
     sda    ->     sda
     cs      ->     5v or 3.3v

spi:

     vcc    ->     5v or 3.3v
     gnd    ->     gnd
     scl    ->     13 (sck)
     sdo    ->     12 (miso)
     sda    ->     11 (mosi)
     cs      ->     10 (ss)

moreover used every available adxl345 library found , failed retrieve data. example:

adafruit library couldn't connect module.

sparkfun library connect (i think) data always: x = 0, y = 0, z = 0.

as far know connections (i2c, spi) good. problem be. bought module, broken?

(adxl345 has regulator doesn't matter)
the adxl345 chip doesn't include regulator guess in case breakout board includes one. please post link board because p.e. sparkfun board doesn't include regulator.

the adxl345 cannot work 5v i/os arduino uno provides. have use level converter. maybe board includes 1 don't have information...

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 ...

Arduino Uno + KTY81/210 temperature sensor

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...
