RTC Clock Shell 32

Structure clock reads and timestamped behavior for RTC modules.

/*
  Roboda verified Arduino sample 0795
  Feature: RTC Clock Shell
  Generated for online build, classroom practice, and hardware upload testing.
*/

unsigned long secondsFromBoot = 0;
unsigned long lastTick = 0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  if (millis() - lastTick >= 1000) {
    lastTick += 1000;
    secondsFromBoot++;
    Serial.print("rtc-shell-seconds=");
    Serial.println(secondsFromBoot);
  }
}

How it works

Practice this Arduino feature with a verified Roboda sketch.

1. Read the constants at the top of the sketch.
2. Wire the pins exactly as listed in the pin map.
3. Upload or compile once before changing values.
4. Change one value at a time and watch Serial Monitor or the output device.
