● Laboratory Equipment

10. Let’s get programming!
We will be demonstrating a simple program to blink Arduino Uno’s onboard LED.
However, we will be using millis() function instead of delay() function
Difference between millis() and delay()?
delay() millis()
Pauses the program for specified amount
of time in ms
Records the current time in ms
Blocking function, ie pauses the program
Non-blocking function ie, continues the
program

11. Blink LED Code with millis()
int time_interval = 1000;
unsigned long int previousBlink = 0;
bool ledState = false;
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
if (millis() - previousBlink > time_interval) {
digitalWrite(LED_BUILTIN, ledState);
ledState = !ledState;
previousBlink = millis();
}
}

12. More experiments to try out
● Create different LED light patterns such as trailing, SOS, alternative, fade
● Use a button to turn on/off LEDs
