Programming ATtiny85 Keyboard with Arduino UNO ISP

-

i'm trying program attiny85 chip arduino uno make function 3 button keyboard computer (hoping make functional on both mac , pc). using digikeyboard.h library , following these instructions (https://github.com/duckythescientist/binarykeyboard) can't tell whether or not code uploaded or not because buttons won't when plug computer. in order understand going on, first print 1s , 0s when keys pressed normal keyboard, i'm not quite sure how button press translates typing in code provided in github? please? i'm not experienced stuff. thanks!

(have set windows mode upon plug in , have played around alt-x , alt-+ windows unicode compatibility still nothing)

try programming tiny85 simple , obvious can tell right away if works. blink. let know uno programmer working (or not!)

then, once assured can iron bugs out of keyboard sketch.

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, i'm getting same error despite have tried 2 boards , done arduino reinstall in windows 7 machine! while trying update "bareminimum" in verbose mode: code: [select] arduino: 1.8.0 (windows 7), board: "arduino/genuino uno" sketch uses 450 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. ___remove___/bin/avrdude -c___remove___/etc/avrdude.conf -v -patmega328p -carduino -pcom8 -b115200 -d -uflash:w:c:\users\rui\appdata\local\temp\arduino_build_445303/bareminimum.ino.hex:i java.io.ioexception: cannot run program "___remove___/bin/avrdude": createprocess error=2, system cannot find file specified  at java.lang.processbuilder.start(processbuilder.java:1048)  at processing.app.helpers.processutils.exec(processutils.java:26)  at cc.arduino.packages.uploader.executeuploadcommand(uploader.java:129)  at cc.arduino.p...

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...
