Hello Friends;
Is it possible with Node -Red. Can ı use serial communication for that, for example;
When I blink, ı want to send to my arduino data "w" and w is setted as forward in arduino. laugh data "s" to backward
Or there is difference method to do this.
This project is important for my internship my friends, if you can help me about it. You will make me happy.
Thanks
my codes

int incomingByte = 0; // assign pin for bluetooth module
