Well it has a lowish input impedance, that might affect the oscillator.

Looks like you need Serial.print(masterid); at the end of loop and you're done.  What am I missing here?

Interesting.  The link goes to a 32 pin, PLCC, One time programmable, parallel interface device.  It has a 16 bit  address bus, 8 bit output, and 3 control inputs - 27 i/o pins plus power.  Are you using a Mega?

I'm trying to use 12v dc motors or lower?

Oh, now there's 2.4GHz involved.  You didn't mention that before. 

You're building a remote control.   How hard would it have been to just say that?  I thought you were trying to capture a signal being sent to a servo.  Wow man, what a waste of f*^%ing time you've been. 

See, I've been sitting here with absolutely nothing to do and shitty weather outside and I could have written your code for you.  I was looking for something to do.  But you wasted so much time being obstinate that now it is afternoon and I'm not interested anymore.  Good job man!

Hallo, ich will folgendes realisieren:

Ich bekomme über Seriell folgende Daten herein:

  • A (Als Buchstabe)
  • B (Als Buchstabe)
  • Werte zwischen 0 und 100%

Wenn ich A empfange, soll Pin7 High und Pin8 Low geschaltet werden,
Wenn ich B empfange, soll Pin7 Low und Pin8 High geschaltet werden.

Der Rest soll auf einem 2x16 LCD Ausgegeben werden, also an sich nur die %, die ich empfange.

Allerdings funktionieren nur die Ausgänge, nicht aber das LCD. Wenn es gut läuft, bekomme ich einen ausgefüllten "Block" auf dem Display oder sonstiges.

Und was noch auftritt: Es werden teils Teile beim Empfangen abgehackt -> aus 1234 wird 234 oder 34, Hallo -> allo oder llo. usw.

Code: [Select]
#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {

  pinMode(7, OUTPUT);
  pinMode(8, OUTPUT);

  lcd.begin(16, 2);


void loop()


  char data =;
  if (data == 'A')
     digitalWrite(8, LOW);
     digitalWrite(7, HIGH);

    else if (data == 'B')
       digitalWrite(7, LOW);
       digitalWrite(8, HIGH);

Hat jemand ne Idee und kann sie mir als Arduino-Neuling gut erklären? Danke

Thanks for clerifying.  Turns out that the problem was a bad UNO. 
Glad to hear you have solved it. Faulty hardware can be very frustrating - especially because it is relatively unusual.

Just out of curiosity was the fault in a genuine Arduino Uno or in a cheaper clone?

I'm not studying something even related to this stuff, it's not my field of study i was surprised by the project the instructor told us about...
Then maybe all the teacher really wants you to do is to say NO and to explain why it is beyond your capabilities based on what you have been taught so far.

You would be amazed at the number of people who don't know how to say NO when that is the correct thing to do.

Non cambia nulla a parte che posso eliminare parti di codice inutile (quindi servito è servito), però il tempo di risposta rimane enorme.
Il problema però è di processing in quanto se mando il comando tramite ide arduino il cambio della luminosità è immediato!
Quindi grazie dell'aiuto!
