Hello all,
I am trying to figure out how to make the arduino accept an equation from the user and spit out an answer with a given input. For example, I want the arduino to accept a user input of "2*x". Then, I will request what "x" do you want. I will say "2" for x = 2, and the arduino should spit out "4" as an answer. These functions can come in a variety of forms including sin, cos, exponentials.
Here is my code thus far. I am having trouble setting up how to read entire strings. Then my next problem is converting that string into a function the arduino can recognize.
Thank you for any help you can offer.
void setup() {
Serial.begin(9600);
}
char p = ' ';
int junk = 0;
void loop() {
int junk = 0;
Serial.println(F("Gimme a function"));
while (Serial.available() == 0); { // Wait here until input buffer has a character
p = Serial.read();
while (Serial.available() > 0) { // .parseFloat() can leave non-numeric characters
junk = Serial.read() ; // clear the keyboard buffer
}
}
Serial.println(p);
}
