Summary of Motorcycle helmet signalling light system created using Arduino
Motorcyclist Adnan Khan built wireless helmet signalling lights using Arduino hardware: an Arduino Uno integrated with the bike indicators, an Arduino Nano embedded in the helmet, and a pair of nRF24L01 transceivers to relay signals wirelessly. Code is available via the project video description; caution is advised to avoid compromising helmet integrity or legality.
Parts used in the Motorcycle helmet signalling light system:
- Arduino Uno
- Arduino Nano
- nRF24L01 transceiver modules (pair)
- Helmet-mounted LED signalling lights
- Wiring and connectors to integrate with bike indicators
- Power supply/battery for helmet electronics
- Mounting hardware for helmet electronics
Motorcyclist Adnan Khan has decided to use a little Arduino programming and microcontroller hardware to create helmet signalling lights that are linked to the indicators on his motorbike providing other road users with plenty of notification on what is next manoeuvre will be. Watch the demonstration video below to learn more about the project which uses an Arduino Uno integrated into the motorbike signalling system plus an Arduino Nano embedded in the helmet together with a pair of nRF24L01 transceivers connecting the two Arduinos wirelessly together.

Adnan has kindly made available the transmitter code and receive a code enabling you to build your very own project via the YouTube description. But as the Arduino Blog reminds us.” Although a neat concept, be sure that you don’t compromise your helmet’s structural integrity or legality if you try something similar! Code is available in the video’s description.”
