Post led flasher circuit?
I want to make two led flasher units...one to flash dot's and one to flash dashes...so a circuit where I can alter the time of flash...to fasten to my dogs collars now the evenings are getting darker.
Anyone got a circuit?

Code:
void loop()
{
  digitalWrite(LED_PIN, HIGH);   // turn the LED on
  delay(1000);                       // wait for a second
  digitalWrite(LED_PIN, LOW);    // turn the LED off
  delay(1000);                       // wait for a second
}
