I was having some problems on a project, so to test my Arduino, I wrote the following program to check things. When I start the serial monitor, the value of i
is 1, but after I start sending numbers, they change into ASCII. Why?
int i = 1;
void setup(){
Serial.begin(9600);
}
void loop(){
Serial.println(i);
if(Serial.available()){
i = Serial.read();
}
}
