Hour hand doesn't move as it should... fix included

[Sarah-C]

If you're finding the hour hand in the factory demo to be a bit wonky... here's the fix.

The hour hand doesn't increment in fractions, so if it's 5 to 3, it looks almost like 5 to 2 because the hour hand hasn't moved on!

The fix shows the hour hand correctly positioned between two numbers for half past the hour:

The fix adds on the angle of the minutes scaled to 1/12 of a circle to the angle of the hour hand... which is simply multiplying the minutes by 5.

lvgl_gui.cpp

void update_sensor(lv_timer_t *timer) {
  float volt = (analogRead(PIN_BAT_VOLT) * 2 * 3.3) / 4096;
  char buf[20];
  snprintf(buf, 20, "bat_volt:%.2f V", volt);
  lv_label_set_text(bat_label, buf);

  struct tm timeinfo;
  if (getLocalTime(&timeinfo)) {
    // The line that fixes the hour hand.
    lv_img_set_angle(hour_img, ((timeinfo.tm_hour) * 300 + ((timeinfo.tm_min) * 5)) % 3600);
    lv_img_set_angle(min_img, (timeinfo.tm_min) * 60);
