arduino uno - DC motor speed control by aurdino using processing -


i have attached video link. in dc motor speed controlled using aurdino uno , processing software moving cursor of laptop. want control laptop aero keys. please send me modified program if possible.

you can find program on this:http://www.instructables.com/id/speed-control-of-dc-motor-from-laptop-using-arduin/

please consult the reference , you'll find handy input functions, including keypressed() function. can use input arrow keys.

void keypressed(){     if (keycode == up) {       //up     }      else if (keycode == down) {       //down     }      else if(keycode == left){       //left     }     else if(keycode == right){      //right      } }

more info can found in this tutorial on user input in processing. (note: wrote tutorial.)

by way, it's hard answer general "how do this" type questions other pointing reference , google. stack overflow designed more specific "i tried x, expected y, got z instead" type questions. need research (googling "processing arrow keys" have gotten pretty far) , post mcve (not external link) if stuck. luck.

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
