Wireless Stage Monitor Kit with Arduino Nano + NRF24
Wireless Stage Monitor Kit: Transmit Click Track BPM with Arduino Nano & NRF24
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Give performers the freedom to move on stage while staying locked to the click track. This kit uses two Arduino Nano boards and NRF24L01 transceivers to create a dedicated wireless pipeline from the mixing console to an in-ear receiver. The result is a low-latency BPM pulse that cuts through live noise, visible as an LED flash and audible through a buzzer.
What You'll Build
You’ll assemble a pocket-sized transmitter that connects to any audio source’s monitor output, converts a click track signal into clean trigger pulses, and beams them wirelessly up to 100 metres line-of-sight. The receiver, worn on a belt or in a pocket, drives a buzzer and LED to deliver a tactile, audible, and visible beat reference — no screens, no distractions.
What You'll Learn
- Configuring NRF24L01 modules for point-to-point communication
- Writing Arduino code to synchronise transmitter and receiver timing
- Filtering audio signals with capacitors to extract stable trigger pulses
- Soldering and assembling a robust pocket-sized prototype

Who This Kit Is For
This kit is ideal for high school and engineering students exploring embedded systems and wireless communication — perfect for CBSE Class 12 physics projects, B.Tech ECE lab experiments, and Smart India Hackathon prototypes. It’s also a practical tool for school rock bands and college music clubs that want a reliable, home-built click track system without investing in professional wireless monitors.
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?

Can this work with a metronome app instead of a mixing console?
Yes. Use the included 3.5mm mono jack to connect the transmitter to a smartphone or tablet running any click track or metronome app. The circuit will extract the audio pulse as long as the output volume is adequate.
Will the NRF24 interfere with Wi-Fi or other stage wireless gear?
NRF24L01 operates in the 2.4 GHz band but uses multiple frequency channels and automatic packet handling. It coexists with Wi‑Fi and most wireless microphone systems without issue, especially with the shielded PCB layout we recommend in the guide.
Do I need to know Arduino programming before starting?
No. The kit includes pre-written, fully commented Arduino sketches for both transmitter and receiver. You’ll upload them using the Arduino IDE, gaining hands-on exposure to the code without writing a single line from scratch.
NRF24L01 transmitter on stage sends click track BPM to wireless earpiece receiver on performer.
