Hi! I have successfully established a Serial connection from Arduino to Processing using the read()-function ( read() / Libraries / Processing.org ). This only returns numbers between 0 and 255 though and I was wondering what the best method for receiving higher number would be? Do I have to use rea…

Hi Map / Examples / Processing.org .

Thanks, but I want to receive let’s say numbers from 0 to 4000 from Arduino and not “map it down” to 0–255…

Hi You didn’t post your code you can send and receive any value you need depending on your code and need Look at this example https://senzor.robotika.sk/sensorwiki/index.php/Processing_7-segment_display

Please consider the following demo and see if you can adapt it to your project. The demo will send random integers from 255 to 1024 from Arduino followed by a line feed. The Processing code will put the incoming data into a string and break it at the line feed. The resulting string is then reconv…

Yes, I wasn’t very specific sorry. I simply want to send sensor values higher than 255 from Arduino to Processing – I understand now Serial.write() and read() in not the way to go. Thank you for your help!

This is very useful, thank you so much!
