No remote, no keypad—just your phone’s BLE signal. This kit turns that into reality with the tiny yet powerful ESP32-C3 Super Mini, a relay, and a few supporting parts. In a single afternoon build, you’ll have a system that opens the garage when it detects your paired phone nearby and closes it safely after 30 seconds.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA compact, self-contained automatic garage door controller.
