just replace switch == HIGH with sensorValue<400 and replace (do this if TRUE) with digitalWrite(13, HIGH) and likewise for (do this if false).

We only provide examples, the rest is up to you.

Pseudo example:

byte latch = 0;  //initial variable
If(switch == HIGH) {  //looks at the switch, if it is high for the first time, LED is ON. If the switch changes then goes high again, LED is OFF

!latch; // This detects whether the switch changed or not.

latch ? (do this if TRUE) : (do this if FALSE);  //conditional statement,  compressed IF/ELSE statement
}

Did you by any chance do a search in the forum for 4x3 keypad? Me and a few other people helped one guy with a keypad, and his code is somewhere in this forum. You just need to find it.

Ok the Blink LED works so, include the softwareSerial in the blink LED code and set the RX pin to one your not going to use then see if you get the same error.

Your code compiles fine with a regular UNO/Mega board, so it has to be an issue with the software.

save any changes to the code and restart the program, that usually fixes it.

Maybe you put the Attiny software in the wrong location. I dont have an Attiny so I wouldn't know off hand, but read this and relocate it.

Im guessing your trying to make an ICade? In which case, others have posted codes that do work(recognize key functions) with the IPad, but they also had other issues.

Your interfacing Windows key commands with an IPad, I dont think the Key functions are the same. Did you do any research as to what keys can be recognised? Try going back to "U, D, L, R" keys

Where is your baud rate?

mySerial.begin(9600);

You need to put the stuff in your IF statements in { }

example.

Code:

if(digitalRead(0) == LOW)                      //UP
 {
  Keyboard.press('U');
  Keyboard.release('U');
  delay(ButtonDelay);
 }

You need to post a picture or a link to the type of motor you have, because im not aware of ANY female plug that exists, to do what you want.

Post the code you have as of now.

It's just to mount the motor in certain brackets. Its usually used to save some space and not need to use screws or other bulky clips to hold the motor in. Actually I have some cars that use it as a vibration damper. Motor clips don't hold onto the motor too well, so that part is used to reduce some of the motor vibration. Screws work just as well thou.

Yes, yes, yes and that depends on your code. If it is a LONG code then you might have some memory issues, but from what your telling us, it won't be a problem.
