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
