Welcome to FlashComm--Light-Comm, a project designed for analog communication that converts audio signals into light, transmits them using a simple LED, and then converts them back into electrical signals for output through a speaker. This project demonstrates the application of modulation and demodulation techniques to ensure effective signal management with minimal noise interference.
FlashComm--Light-Comm explores the fascinating realm of analog communication by using light to transmit audio signals. This project uses basic components like an LED and a photodiode to convert audio signals into light and back into electrical signals, showcasing the practical application of modulation and demodulation techniques to minimize noise and enhance signal clarity.
- Audio to Light Conversion: Converts audio signals into light using an LED.
- Light Transmission: Transmits the signal via light, which can be captured by a photodiode.
- Light to Audio Conversion: Converts the received light signal back into electrical signals and outputs through a speaker.
- Modulation Techniques: Implements effective modulation and demodulation techniques to manage signal quality and reduce noise interference.

- LED (Light Emitting Diode): Converts the electrical audio signal into light.
- Photodiode/Phototransistor: Captures the transmitted light signal and converts it back into an electrical signal.
- Amplifier Circuit: Amplifies the weak electrical signals received from the photodiode.
- Speaker: Outputs the converted electrical signals as audio.
- Amplitude Modulation (AM): Used to modulate the amplitude of the light signal in accordance with the audio signal.
- Demodulation: Converts the received modulated light back into an audio signal with minimal noise interference.
- Noise Reduction: Ensures that the transmitted signal is clear and free from noise interference through careful modulation and filtering techniques.
- Signal Integrity: Maintains the integrity of the audio signal from transmission to reception.
