433MHz RF Button Remote Kit with Arduino Uno + LED
Build a 100-Metre Wireless Remote Control with Arduino Uno – 433MHz RF Button LED Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine pressing a button in one room and watching an LED light up across your home or school lab – without Bluetooth, WiFi, or internet. This kit lets you build exactly that, using 433MHz radio waves that travel up to 100 metres in open air. It’s the simplest way to see how wireless remote controls, garage door openers, and simple IoT command links work.
What You'll Build
A two-node wireless system: one Arduino reads button presses and transmits a signal, the other receives it and lights the corresponding LED. You’ll assemble both circuits on breadboards, fine-tune the antenna placement, and write the code that makes the link reliable over distances that surprise even older students.
What You'll Learn
- Encode and decode digital signals over RF using ASK modulation
- Wire 433MHz transmitter and receiver modules correctly without soldering
- Program an Arduino to send and receive data packets with error handling
- Troubleshoot wireless range, interference, and antenna orientation

Who This Kit Is For
This kit fits naturally into CBSE Class 6–10 science projects where students demonstrate electromagnetic wave concepts. 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.
Built and Backed by Compoden
Every 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. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to open your kit’s AI companion, trained specifically on this project. For trickier issues, send a photo of your wiring to our WhatsApp support – we’ll help you debug the RF link in real time.
Will the remote work through walls or concrete?
The 433MHz signal passes easily through wooden walls, glass, and drywall. 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.
Can I add more buttons or control more LEDs?
Yes. The two included buttons can already map to the three LEDs with a simple code tweak. By modifying the packet structure you can expand to many more commands – a great next step for exploring RF protocols.
Do I need soldering?
No soldering is required. All connections are made on the included breadboards using the M-M jumper wires. The transmitter, receiver, LEDs, and buttons plug directly into the breadboard.
433MHz transmitter and receiver modules send button state wirelessly over 100m range. LED responds.
