Sooner or later, the Arduino starts to feel a little claustrophobic. Your sketches start running out of memory, so you need more RAM. You want to talk serial to another peripheral (like an RFID Module) AND watch the action in the Serial Monitor at the sa
This project features a smart RFID door lock, weather station (which tells you the temperature, humidity, and gas quality at home), motion detector, plant watering reminder, mood lighting, and a real-time camera feed. To make things better, you can also control all of your household applianc...
