After ten seconds it will multiply the current heart rate with six and will give the Heart Beat Per Minute.Now click this HB button and it will start counting the HB as well as will count the Time in seconds.Now run your Proteus Simulation and you will get something as shown in the below figure:.So, use the above code and get your Hex File from Arduino Software and update it in your Proteus Simulation.So, when TimeinSec will become equal to 10 then I am simply multiplying it with 6 and updating it on the LCD.On each interrupt, it executes timerIsr() function, in which I have placed a check that whenever this interrupt will call we will increment TimeinSec variable.In this code, I have used a TimerOne Library which creates an interrupt after every 1sec.If((digitalRead(HBSensor) = LOW) & (HBCheck = 1)) If((digitalRead(HBSensor) = HIGH) & (HBCheck = 0)) put your setup code here, to run once: Here's the code which I have used for this Heart Beat Monitor using Arduino:.Now let's have a look at the programming code for Heart Rate Monitor: There's also a Button attached to Pin # 2, so when we press this button our Arduino will start counting the Heart Beat and will update it on the LCD.As you can see in the above figure, we have our Arduino UNO board along with LCD and Heart Beat Sensor.
