Sending data from Node.js side to Arduino side
Hello,
I carefully followed your tutorial, I'm able to successfully send data from Arduino side to Node.js but vice-versa is not happening.
My Arduino code is:
`char incomingChar;
String incomingStr="";
void setup() {
Serial1.begin(115200);
pinMode(13, OUTPUT);
}
void loop() {
while (Serial1.available()) {
incomingChar = (char)Serial1.read();
incomingStr=+incomingChar;
if (incomingChar == '\n') {
incomingStr.trim();
String text=incomingStr;
incomingStr="";
if(text.equals("on"))
{
digitalWrite(13,HIGH);
}
}
}
}`
When I do console.log("on\n"); on node.js. The led on pin13 doesn't light up.
Please Help.
