Morse Code Visualizer/Decoder: Geometric Segments for Dots and Dashes

This example demonstrates how a Morse code dot/dash sequence can be visualized as structured geometric segments, and then decoded back into the corresponding letters through an interactive mapping. The mathematical ideas involved are discrete sequence-to-graphics encoding, piecewise segment construction, and rule-based symbol matching using the standard Morse table. From the construction summary, the key GeoGebra step is using the command “Segment, First” to build the segment primitives that represent dots and dashes. The interface is organized via objects such as button1/button2/button3 and control elements like Start, along with letter targets (E, I, S, H, V, U, F, A, R, L, W, J, P, T, M, O, G, Q, Z, N, K, Y, C, D, X, B). Additional objects (f, g, h, i, j, k, l, m, n, p) support storing or updating the constructed paths/outputs during the visualization and decoding workflow. Suitable for secondary-school through undergraduate learners, especially for lessons on discrete mathematics, encoding concepts, and interactive geometric construction in GeoGebra.
