Nano Bike Computer Kit with Arduino Nano + LED
Build Your Own Speed & Distance Bike Computer with Arduino Nano and OLED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Mount this compact gadget on your handlebars, give your wheel a spin, and watch live speed and trip distance appear on a crisp OLED screen — all calculated by an Arduino Nano. It’s the thrill of riding with a digital assistant you built from scratch, learning how everyday objects use sensors and microcontrollers.
What You'll Build
You’ll assemble a real bike computer that bolts onto any bicycle. A magnetic reed switch detects each wheel rotation; the Arduino Nano turns those pulses into speed in km/h and cumulative distance travelled. The 0.96-inch OLED displays the data clearly, while a DS3231 real-time clock lets you log ride times. The whole unit runs on a rechargeable LiPo battery and fits inside a sturdy ABS enclosure — ready for your next ride.
What You'll Learn
- Interface a magnetic reed sensor to count wheel rotations
- Program an Arduino Nano to compute speed and distance from pulse timing
- Drive a 0.96-inch OLED display for real-time readouts
- Integrate a DS3231 RTC module to timestamp ride data

Who This Kit Is For
Perfect for students in CBSE Class 6–10 science projects, ATL Tinkering Labs, and young hobbyists eager to blend cycling with coding. Under adult supervision for soldering, even a 10‑year‑old can proudly build a working bike computer. Engineering aspirants from NIT, VIT, BITS, and state varsities will find it a rewarding first embedded system project.
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?

Is soldering required?
Yes, but the kit includes a soldering iron and solder wire. We recommend adult help for builders under 14.
Can I mount it on any bicycle?
Absolutely. The ABS enclosure includes mounting holes and cable ties for secure handlebar attachment on most bikes.
Does the kit include the Arduino code?
Yes. The QR code gives you the pre-written sketch, plus a wiring diagram and build guide.
Reed switch on wheel counts rotations. Nano calculates speed and distance. OLED mounted on handlebars.
