Maps and Locations (Smart Scale Map Enlargement & Coordinate Plotter)
Source: Stemoto Original
Enlarge mini maps using scale factors (1 cm on map = 5 meters in real life!). A servo-driven 2D plotter arm draws scaled map paths on a grid drawing board based on input scale ratios.
Categorisation
Props & Materials Required
- •2D XY servo plotter mechanism with drawing marker pen
- •Map grid mat (Scale 1:1, Scale 1:2, Scale 1:5)
- •ESP32 controller board
- •16x2 LCD display screen
- •DFPlayer Mini MP3 module + 3W speaker
Step-by-Step Instructions
Input Map Route Coordinates
Select route: 'School (2,2) → Park (4,6) → Library (8,6)'.
Select Scale Ratio Factor
Select Scale: '1 cm = 2 meters (Scale x2 Enlargement)'.
Servo Plotter Draws Map
2D servo plotter arm lowers marker pen and draws the enlarged route on grid paper.
Real-World Distance Announcement
LCD displays 'Map Distance: 12 cm = Real Distance: 24 Meters!'. Speaker verifies scale accuracy!
Why It Works & Notes
Maps and Locations explores scale reduction/enlargement (how 1 cm on a city map represents 100 meters on the ground). Using a 2D servo plotter arm to draw map routes at different scale ratios makes map scale visual and physical.
