Hi, I am working on an Automated Gardening System. I have finished a moisture sensor and am now working on the code. I have finished the code for the moisture sensor and am working on one for the web scraper. When I am combining them both an error keeps popping up. Here is the code.
# include from
int s0=2; //value of select pin at the 4051 (s0)
int s1=3; //value of select pin at the 4051 (s1)
int s2=4; //value of select pin at the 4051 (s2)
int count=0; //which y pin we are selecting
void read_message() {
debug("checking for messages");
String indata = String();
if(!(Serial.available() > 0)) {
debug("no messages");
return;
}
else {
while (Serial.available() > 0) {
debug("available");
char incomingByte = Serial.read();
if (incomingByte == '\n') {
break;
}
indata += incomingByte;
}
}
}
void setup()
{
Serial.begin(9600);
pinMode(s0, OUTPUT);
pinMode(s1, OUTPUT);
pinMode(s2, OUTPUT);
pinMode(A0, INPUT);
}
void loop (){
debug("looping");
read_message(); // get any new messages from the computer
}
void send_message(int type, String message) {
Serial.println(String(type) + String('\t') + message);
}
// Message types
int DEBUG = 0;
int SENSOR = 1;
int FORECAST = 2;
unsigned int counter = 0;
//if true, prints everything out, else nothing printed
boolean log_output = true;
void debug(String message) {
if(log_output) {
send_message(DEBUG, message);
}
}
void process_debug(String message) {
send_message(DEBUG, message);
}
# SENSOR:<integer>

This is the error. ‘from’ does not name a type.
What does this error mean? Any help is appreciated.
