it doesn't work well
is there is tutorial
or code can help me
well, i send binary data
what i need to change in the receiver code
val = analogRead(potpin); int val2= String(val,BIN).length(); val2 = map(val2, 0, 1023, 0, 179); // scale it to use it with the servo (value between 0 and 180) Serial.write(val2);
You convert the value you got from analogRead() to a String, in binary format, then take the length of the String, scale it and send that value to the receiver.
