The best example to explain the drawback of delay function is using two push buttons ... to make the logic clear and make yourself comfortable with millis() before starting to program Arduino UNO for ...

#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 ...

For example, let’s re-create our program ... so why would anyone wish to employ the millis() approach? Well, one problem with using the delay() function is that it prevents the Arduino from performing ...

This code uses the "millis" function to "delay" an action (in this case, illuminate an LED (built-in and/or digital pin 13) five seconds after a button (digital pin 12) is pressed). The delay command ...

One of the most commonly asked Arduino-related questions is how to write ... flashing the LED without any change in delay or any other disruption, even when the millis register overflows back to 0. We ...

Literally, ATtiny85 is a scaled-down version of the Atmega microcontroller on Arduino boards with just a few I/Os ... of phase-correct and fast PWM used for functions such as delay() and millis(). The ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

For example when a delay() function is used it actual sets the Timer and Counter Register bits of the ATmega microcontroller. In this arduino timer tutorial we are going to avoid the usage of this ...
