One of the most commonly asked Arduino-related questions is how to write one’s programs in such a way that they can accommodate an overflow/wraparound condition in the millis() function. One of the ...

It’s possible to write one’s programs in such a way that they can accommodate an overflow/wraparound condition in the millis() function, but how does this actually work? It’s possible to write one’s ...

That's exactly the way we're taught NOT to implement delay, and it doesn't handle the wrap of millis () corrected (ie when start+ms is larger than 32bits, and thus stop will be truncated and millis () ...

#define SONAR_NUM 3 // Number of sensors. #define MAX_DISTANCE 200 // Maximum distance (in cm) to ping. NewPing sonar[SONAR_NUM] = { // Sensor object array. NewPing(4, 5, MAX_DISTANCE), // Each sensor ...
