Arduino Uno Motorised Bike Gear Indicator Kit: Display Gear Position Instantly While Riding

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

For cyclists who want to know exactly which gear they’re in without looking down, this kit builds a handlebar‑mounted dashboard indicator with a servo‑driven needle and OLED display. Using two Hall sensors—one on the wheel, one on the crank—the Arduino calculates the current gear ratio from rotational speeds and points the servo to the corresponding gear number. No more guesswork; a quick glance shows the active gear, even while pedaling.

What You'll Build

You’ll assemble a compact module that reads magnet pulses from the wheel spoke and crank arm, processes data on the Arduino Uno, and drives an SG90 servo to a marked gear scale. The 0.96‑inch OLED shows the computed gear number in real time, and the system updates continuously as you ride—transforming raw sensor pulses into a visible, immediate gear position.

What You'll Learn

• How Hall effect sensors detect magnetic fields and generate pulse signals for rotational measurement
• Interrupt‑based programming on the Arduino Uno to count pulses from two sensors simultaneously
• Calculating gear ratio from wheel and crank RPM and mapping it to a servo angle
• Integrating an OLED display for live data visualisation of gear state
