LED modulation → photodiode → amplification → LCD alert.
System overview
Optical communication build with LED transmission, photodiode reception, amplification and microcontroller-driven LCD alerts. Proteus simulation and laboratory checks explore braking/junction messages over a short-range light link.
Optical message path
- Message encoding
- LED modulation
- Photodiode reception
- Signal decoding
- LCD alert
The circuit demonstrates an optical data channel between a transmitter and receiver.
Circuit responsibilities
- The transmitter maps message information to changes in LED output.
- The optical receiver converts incoming light into an electrical signal for the microcontroller.
- The decoding logic interprets the signal and selects the corresponding message.
- An LCD makes the received result observable during the circuit demonstration and simulation.
