MbedOS • Edge Impulse • TensorFlow Lite

• ESP32-CAM handles capture. STM32 runs display and logic for on-device face recognition.
• Trained lightweight models with Edge Impulse. Deployed with TFLite for efficient inference.
• Bridged microcontrollers over I2C and UART with live identity feedback on an embedded display.

PitchScope (in development)

STM32 • OLED • FFT • Audio DSP • BLE • KiCad

• Visualizes pitch over time to spot drift, shaky fretting, and vibrato technique.
• Mic plus preamp feeds FFT to track dominant frequency and draw traces on an OLED.
• Optional BLE sync for mobile heatmaps after practice.

Temperature-Controlled Fan

STM32 • PWM • Digital Temp Sensor • Control

• Built a closed-loop system that reads room temperature and adjusts fan speed with PWM on an STM32.
• Tested across different loads and noise conditions to keep the output steady.

Smart Plant Monitor

ESP32 • Soil Moisture • DHT22 • OLED • MQTT

• Tracks soil moisture, temperature, and humidity for indoor plants with an ESP32.
• Local OLED readout for quick checks. MQTT publishes live data to a web dashboard.

Self-Balancing Robot

Arduino • MPU6050 • PID • DC Motors

• Built a two-wheel inverted pendulum that balances upright using accelerometer and gyro data.
• Implemented sensor fusion and a PID loop to stabilize motion against pushes and small bumps.
