Commutatore 2 vie

-

salve raga, sto seguendo un progetto che crea una mini sveglia usando display lcd e modulo rtc.
in questo progetto serve anche un interruttore 3 posizioni quindi on-off-on .
avendo scarse conoscenze di elettronica, volevo usare un commutatore che gia possiedo ma non trovando niente su come poterlo collegare non come fare perchè il mio commutatore è diverso da quello del progetto.
questo commutatore 2 vie 3 posizioni ha in totale 8 pin sotto.
http://www.commutatori-palazzo.it/italiano/commutatori/pdf/catalogo_palazzo.pdf
pagina 17 c'è il commutatore come al miio.

posso usare questo per avere 3 stati letti da arduino o devo procurarne uno con 3 pin ?

basta che colleghi il com di una via gnd e 2 delle 3 posizioni 2 ingressi digitali, così hai queste 3 possibili combinazioni:
on off
off on
off off

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...
