The Baby Blue Team 11 Oscilloscope ECE342-W25 is an ESP32-based digital oscilloscope featuring two input channels and an LCD display for real-time waveform visualization. Designed to be powered off a battery, this system allows users to display electrical signals by leveraging the ESP32’s ADC1 and I²S to process signal data from the probes. User’s hardware controls include a toggle switch for trigger functionality, two potentiometers for voltage and time scaling, and a channel selection switch. The Y-axis potentiometer also serves as a trigger threshold adjuster when the toggle is enabled. One of the most notable achievements of this project was the ability to measure high-frequency signals without requiring an external ADC, demonstrating the efficiency of the ESP32’s built-in hardware. A key challenge was integrating the potentiometers and trigger toggle switch, as ADC1’s I²S and ADC2’s boot pin conflicts required extensive troubleshooting and reconfiguration. Lastly, the entire system was installed in a custom-designed, 3D-printed case, ensuring user-friendly accessibility with precise cutouts for all controls and the LCD screen. Future improvements could include improving resolution, expanding bandwidth, and enhancing trigger functionality.
