Hi!
Me and my friend need some help with the programming. (We are very new on this).
Our goal is to create a box that opens by a servo when the pulsesensor has measure the "maximal pulse" (that you can by you self decide in the serial monitor). The box will be open for a limit of time and then close again. Then you have to repet the process: Measure the BPM--> the box will open after the maximal pulse has acheved--> Box is open for limit of time and then it will close.
We have done a sketch, but we are getting error like:
-The servo is activ all the time and not depending on the pulsesensor.
Please help us

#include <Servo.h>

Servo luckan; // Vi definerar servon som obejkt för att kontrollera luckan.
long pos = 0; // Pos är variabel som tilldelas för att förklara luckans position.
const int PulseWire = A0;
int anvandignor = 550; // Vilka signaler den ska använda som beat och vilka den ska ignorera.
// int pulseSensor=A0;
PulseSensorPlayground pulseSensor;
int MaxPuls = 120; // Skriva in sin maxpuls (helst i seriall monitor)
void setup()
{
Serial.begin(9600);
pulseSensor.analogInput(PulseWire);
if (pulseSensor.begin())
{
Serial.println("We created a pulseSensor Object !");
luckan.attach(9);// Servon ska tillhöra pin 9.
}
}
void loop()
{
int myBPM = pulseSensor.getBeatsPerMinute(); // Calls function on our pulseSensor object that returns BPM as an "int".
if (Serial.available() < 0)
{
pos = Serial.read();
}
if (pulseSensor.sawStartOfBeat()) // Testar ifall den får ett beat
{
delay(15000); // Väntar i 15 sekunder och sedan printa ut
Serial.println("Kom igen, kämpa! "); // If test is "true", print a message "a heartbeat happened".
Serial.print("BPM: "); // Print phrase "BPM: "
Serial.println(myBPM); // Print the value inside of myBPM.
}
if (myBPM > MaxPuls) // Vi vill att den ska skriva att "om pulsmätaren kommer upp till 120"...
{
Serial.println("Yey, Let's get HIGH on candy! ");
Serial.print("BPM: ");
Serial.println(myBPM);
for (pos = 10 ; pos <= 90; pos += 1) // går från 0 grader till 120 grader.
{
// in steps of 1 degree
luckan.write(pos); // Säger till luckan att gå till den bestämda positionen.
delay(800); // Väntar 800 ms
}
for (pos = 90; pos >= 90; pos -= 1) // Går från 120 grader till 0.
{
luckan.write(pos); // Säger till luckan att gå till den bestämda positionen.
delay(20); // Väntar 50 ms.
}
