this is a custom board using the MCU "STM32F107RBTx". the reason why i chose this MCU is because i wanted to implement circuits for ethernet communication, CAN communication and USB communication.

# Description In a world cluttered by chaos, she is the solution. The Disciplinary Crimson Robot Maid is a state-of-the-art android built on a single principle: perfection is achievable through protocol. Her programming extends beyond domestic chores to encompass the management of her master's life, from daily schedules to personal habits.

Using the Raspberry Pi Pico microcontroller, I was able to design a hearing aid with volume control. The components and a description of why they were used: MCP3008 - CONVERTS ANALOG AUDIO SIGNALS INTO DIGITAL DATA CONVERTED BY THE MICROCONTROLLER MCP4725 - CONVERTS DIGITAL AUDIO SIGNALS TO ANALOG SO THE AUDIO CAN BE OUTPUTTED THROUGH A SPEAKER LM358 - USED TO AMPLIFY WEAK SIGNALS IN THE HEARING AID, REMOVES UNWANTED FREQUENCIES SPU0410LR5HQB - THIS COMPONENT IS A MICROPHONE, SPECIFICALLY CHOSEN BECAUSE IT IS OMNIDIRECTIONAL AND CAN CAPTURE AMBIENT SOUNDS, IT IS A SMALL COMPONENT PERFECTLY USED FOR NOISE REDUCTION, ASSISTING IN CAPTURING CLEAR AUDIO PAM8302AASCR - EFFICIENTLY AMPLIFIES AUDIO, AUDIO SIGNAL FROM DAC (VOUT) IS FED INTO THE INPUT OF THE AUDIO AMPLIFIER, WHICH OUTPUTS IDEAL FREQUENCY AUDIO CEM-1203(42) - SPEAKER WHICH OUTPUTS THE AUDIO AMPLIFIER MODIFIED FEATURE: POTENTIOMETER - WITH THE CCW CONNECTED TO GND, CW CONNECTED TO VDD, WIPER CONNECTED TO PIN 27 OF THE MICROCONTROLLER, THIS FEATURE IS A VOLUME ADJUSTER, WE ARE ABLE TO FULLY TURN OFF AND ON THE VOLUME BY ADJUSTING THE HEARING AID FOR THE IDEAL AUDIO OUTPUT
