The CardioWave Heartbeat Simulator is an innovative project that intricately blends biology with technology. It aims to simulate the human heart's rhythm using a potentiometer to control a buzzer, creating a range of heartbeat sounds. From a calm, steady pulse to a rapid heartbeat, this project captures the essence of our vital life force in an electronic form. Ideal for educational purposes, the CardioWave offers a unique hands-on experience for understanding heart rates and their variability.
- Microcontroller (e.g., Raspberry Pi Pico)
- Buzzer (PWM compatible)
- Potentiometer (10k ohm)
- Breadboard and connecting wires
The Python script for the CardioWave project is designed for microcontrollers like the Raspberry Pi Pico, making use of the machine library for Analog-to-Digital Conversion (ADC) and Pulse Width Modulation (PWM) control.
heartbeat_signal(frequency, duration): Generates a heartbeat sound with a specified frequency and duration.continuous_beep(frequency): Emits a continuous high-frequency beep, simulating a flatline.while TrueLoop: Continuously reads the potentiometer value to adjust the heartbeat frequency or trigger a flatline simulation.
- Potentiometer at 0: Triggers a continuous high-frequency beep, representing a flatline.
- Potentiometer above 0: Generates heartbeat sounds with frequency proportional to the potentiometer's value.
A comprehensive demonstration of the CardioWave Heartbeat Simulator is available in the attached video, "CardioWave Sim." This video showcases the functionality of the project, providing viewers with a clear understanding of its capabilities.
