ATL Tinkering Lab mentors can run a full classroom session around building the transmitter‑receiver pair. First‑year B.Tech students (ECE\/EEE) will appreciate a practical introduction to RF modules before encountering them in later semesters, and it’s a fun way for any young maker to start tinkering with wireless control.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt and Backed by Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup.

Concrete and metal reduce range significantly; indoors you can expect 30–50 metres through a couple of walls, while outdoors with line‑of‑sight you will get the full 100 metres.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I add more buttons or control more LEDs?\u003c\/summary\u003e\u003cp\u003eYes.
