We have been working on this "disaster bot" code for days and hours. AFter all of our hard work, Arduino gives us this error code: expected primary-expression before void. Please please please assist we are so desperate to get this to work. Here is our code below. Please.
// HEARTBEAT SENSOR (displays heart rate on LCD screen)
int sensorPin = A0; // This is the analog sensor pin the backwards S pin is connected to
// you can use any of the analog pins, but would need to change this to match
double alpha = 0.75; // This code uses a rather cool way of averaging the values, using 75% of the
// average of the previous values and 25% of the current value.
int period = 20; // This is how long the code delays in milliseconds between readings (20 mSec)
