Arduino Clear Serial

Arduino Clear Serial Monitor
Arduino Clear Serial Port
Arduino Clear Serial Buffer

So Nick, please answer this for me: If I have a Pi running Python sitting at a ser.readline waiting for input as a data logger, and it is fed via serial by Arduino taking readings then sending them as a batch with tab delimeters, then using delay(120000) so the batches come in every two minutes, the Python innards probably immediately read in. It is not clear what do you really want to do. Anyway, please note: In your C# code, if you enter, for instance, '1' in your TextBox then four bytes are sent to the serial line: three 0s and a single 1 (the 0s won't be handled by your Arduino code). In your Arduino code you didn't check if Serial.read returns -1 (i.e. No data available). Serial); // Wait until Serial is ready - Leonardo Serial.println('Enter LED Number 0 to 7 or 'x' to clear'); Firstly, we have the command 'Serial.begin(9600)'. This starts serial communication, so that the Arduino can send out commands through the USB connection.

Serial.flush();

It's just a simple function which clears the data on transmitting pin of Arduino.

while(Serial.available());

So, here's the small code which I have also used in the Arduino Serial Write tutorial but now I am using Arduino Serial Flush command too.

In the above code I have simply added the Arduino Serial Flush code and now it will take a little more time to complete because now it will make sure that all the data has been sent.

So, that's all for today. I hope you guys have enjoyed this short Arduino Serial Flush tutorial. If you have any questions, please ask in the comments. Take care !!! :)
