hello , i want to know if it's possible to use a text typed on a keyboard as input , for exemple when i type on my keyboard : "hello" , then it turn on a led. and if it's possible can someone put me a link on a tutorial or infos. thanks in advance.

Hi, Of course it can be done!! try something like this: int ledPin = 13; void setup() { //Create Serial Object Serial.begin(9600); pinMode(ledPin, OUTPUT); } void loop() { //Have the arduino wait to receive input while (Serial.available() > 0) { //Read the Input int val = Ser…

tyvm but i dont understand how this code will turn on the led when i type : hello on my keyboard?

keneda83: tyvm but i dont understand how this code will turn on the led when i type : hello on my keyboard? It won't. It reads a single numeric character and acts on that. Have a look at Serial input basics for ideas of how to read a string of characters and acto on them.

ok thx for the link , it's what i need , a way to read a succecion of characters not just a single one thx again :slight_smile:

Also, you should probably get a "real" serial terminal emulator like Putty or Tera Term if you are going to play with this kind of thing.

Very simple code for turning the arduino LED on/off via the serial monitor. // zoomkat 8-6-10 serial I/O string test // type a string in serial monitor. then send or enter // for IDE 0019 and later int ledPin = 13; String readString; void setup() { Serial.begin(9600); pinMode(ledPin, OUTPUT);…

  Serial.flush();

Block until the outgoing serial buffer is empty, even though you haven't written anything to the buffer. Why?
