Run the Seven-Segment Display MicroSim in fullscreen

Description

This MicroSim demonstrates how seven-segment displays work by allowing users to control individual segments. Seven-segment displays are the most common way to display digits on digital clocks, calculators, and many electronic devices.

Key features:

  • Interactive control of all 7 segments (A-G)
  • Visual representation of segment layout
  • Learn the standard segment naming convention
  • See how different combinations create digits 0-9

How to Use

  1. Toggle individual segments using the controls
  2. Observe how each segment contributes to the display
  3. Try to create each digit from 0 to 9
  4. Note the segment pattern for each number

Lesson Plan

Learning Objectives

After completing this lesson, students will be able to:

  • Identify all seven segments by their standard names (A-G)
  • Determine which segments must be lit to display any digit
  • Explain how binary values control segment states

Target Audience

  • Grade level: Middle school to high school (grades 6-12)
  • Prerequisites: Basic understanding of binary on/off states

Activities

  1. Exploration Activity: Manually create each digit 0-9 using the segment controls
  2. Guided Investigation: Record the binary pattern for each digit in a table
  3. Extension Activity: Design letters using the seven segments (e.g., A, b, C, d, E, F for hexadecimal)

Assessment

  • Can students recreate any digit from 0-9 without reference?
  • Can students explain why certain letters cannot be displayed clearly?
  • Can students identify which segment is faulty given a broken display?
