Mosfet bruciato, come verificare?

-

salve ragazzi, qualche giorno fa ero intento modificare la mia stampante 3d, purtroppo per sbaglio ho cortocircuitato cavi della ventola sul pwm, tal punto da far saltare la pista di rame.
oggi ho saldato la pista, purtroppo la ventola resta accesa, senza dare ulteriori segni di vita.
verificando ho notato che il mosfet è completamente in corto, tutti e tre pin sembrano diventati un unica cosa.
ho provato chiedere sul forum di reprap, purtroppo, per quanto quei ragazzi siano gentili, oltre "ricompra la scheda", "tienitela così","estrusore otturato" non son capaci di fare.
per carità, la scheda che uso, gt2560 costa sui 40 euro, ma non voglio crederci che non si possa riparare...
questo è dovrebbe essere il pwm:

se posti pure delle foto di come è la situazione è meglio ;)

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...
