The Transport Museum (Smart Speed, Distance & Time Formula Bot)
Source: Stemoto Original
Test different modes of transport (Bullock Cart 5 km/h, Steam Train 40 km/h, Bullet Train 250 km/h). Optical speed sensors on a track measure car speed and calculate Speed = Distance ÷ Time.
Categorisation
Props & Materials Required
- •Model transport vehicles (Bullock Cart, Bus, Electric Car, Bullet Train) with NFC tags
- •1-Meter track with 2x IR break-beam speed gates
- •ESP32 controller board
- •16x2 LCD display screen
- •DFPlayer Mini MP3 module + 3W speaker
Step-by-Step Instructions
Scan Vehicle Tag
Scan 'Bullet Train' vehicle on the start gate. Speaker: 'BULLET TRAIN loaded! Ready for high-speed test!'
Launch Vehicle Down Track
Release vehicle down 1-meter track.
IR Gate Speed Calculation
Gate 1 starts timer, Gate 2 stops timer (0.4 seconds). Controller computes Speed = 1m / 0.4s = 2.5 m/s (250 km/h scale)!
Speed Comparison Display
LCD displays: 'Speed: 250 km/h! 50x faster than a Bullock Cart!'
Why It Works & Notes
The Transport Museum links history of travel with the Speed-Distance-Time formula. Measuring travel time across a 1-meter track gate calculates real-time speed in cm/s and converts to km/h.
