-Frequency Coded Encoding and Decoding Mechanism

Technologies: ARM Cortex M0+, Embedded C, Bluetooth, UART and ADC

• Developed a secure, anti-interception communication device using a microprocessor.

• Engineered a Fibonacci-sequence frequency hopping algorithm to encrypt and transmit analog voice signals, ensuring secure data transfer.

• Integrated complex hardware peripherals including HC-05 Bluetooth modules, microphone and capacitive touch sliders utilizing UART, GPIO and ADC communication protocols

IMPORTANT NOTE: Microphone part so decoding part doesn't work very well. So it should be developed but other parts works as described
