Hi, just a quick question (sorry we are just starting on Arduino):
Is it enough to put 1ms delay between analog reads? Or what should it be?
In addition, I'm trying to send a message like this via Serial: 0303030101
Serial.print("0");
Serial.print("3"); // just an example, it gets the int from a variable
Serial.print("0");
Serial.print("3"); // just an example, it gets the int from a variable
Serial.print("0");
Serial.print("3"); // just an example, it gets the int from a variable
Serial.print("0");
Serial.print("1"); // just an example, it gets the int from a variable
Serial.print("0");
Serial.println("1"); // just an example, it gets the int from a variable
If i put a delay of 2 seconds after the last Serial.println, my receipient can receive the message without any problem. However if i reduce the delay to less than 1 second, sometimes my receipient don't even get my message at all. Any idea what has happened?
Delta_G:
You ask about digital reads and then abruptly switch to a serial issue. What's the real question? Code?
Hi sorry yeah we are facing 2 issues so I should probably state it more clearly in my initial post.
The first question we have is we would like to know what is the minimal amount of delay time is required between each analog reads...
The second question is regarding the serial writing, we are not sure why putting the delay works (removing the delay causes message not being sent, occurs in a random fashion)
Delta_G:
For the analog question the answer is that you don't need any delay. Sometimes it's good to toss the first read after changing pins. But no delay is required.
For the serial issue: there's no way we could know why your code doesn't work without seeing the code for the sender and receiver.
Ok noted. Thanks for your help! We will continue to investigate on the serial issue and I will post another thread about it (if we require help) so as to keep this topic relevant.
