Plugged LCD the wrong way, is it dead now?

-

hi guys,

this first post, before posting searched forum similar problem mine. didn't find definitive answer, here goes.

i have (or had) working lcd display. project, have pcb header lcd connected (image 1). header numbered this;

upper row:1,3,5,7,9,11,13,15
lower row:2,4,6,8,10,12,14,16

i wasn't paying attention when connected it, , did follow (image 2).
upper row:1,2,3,4,5,6,7,8
lower row:10,11,12,13,14,15,16

after doing got sort of squares displayed (image 3).
then noticed wiring wrong, wired correct way , still got same results.

i unplugged pcb, , plugged breadboard test simple "hello world" program. still same blocks in image 3. if touch of lcd while it's displaying these blocks, image fades , comes back.

so wonder, did kill lcd when plugged wrong way? it's not dead yet, more brain dead still... :smiley-confuse:

thanks!

it dead, since working when correctly connected , not.  electronic chips typically destroyed when power connected wrong way around.  board incorporate reverse connection protection, sadly not appear true here.

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...
