Description: Sensors trigger LED sequences to analogize how signals travel along neurons.
Objective
Model stimulus → signal propagation → response using simple electronics.
Materials
- Addressable LED strip, microcontroller
- Input sensors (touch, sound, color, ultrasonic)
- Buttons, jumper wires, power supply
Procedure
1. Map each sensor to a “stimulus”.
2. Code a one-direction LED chase as the “action potential”.
3. Add timing to show refractory periods.
4. Display a labeled diagram: dendrite, axon, synapse (analogy).
Conclusion
Sequential activation illustrates directionality and timing of neural signals.
