Hi First of all hi to everyone on the forum, I have just bought and built a Smartrap (Ebay version), but have problem and I don't have a clue whether this is normal or whether something isn't working. What works? I have no SD card installed. It is hooked up to my Windows pc (tried on my Linux laptop with same result). The Arduino flashes once. The LCD all works.
