TECHNICAL PROJECTS
Embedded Projects
REAL-TIME WATER QUALITY MONITORING SYSTEM (DECEMBER, 2023)
ESP32, Temperature sensor, Ph sensor, TDS sensor, Turbidity sensor, html, database
Equipped with four sensors measuring temperature, pH, turbidity, and total dissolved solids, the system provides a comprehensive overview of water quality. Data from these sensors are transmitted in real-time to a web server, offering users accessible and analyzable information through a user-friendly dashboard. This project won the first position in the UVic Ocean Challenge 2023. I was responsible for the circuits and C++ coding of the MCU in a team of 5 members.
​
MATERIAL SORTER (APRIL, 2023)
Atmega 2560, Reflectivity sensor, Hall Effect sensor, Optical sensor, FIFO queue, DC motor, Stepper motor, ADC, PWM
The goal of this project was to sort items of varying materials and colors into the appropriate bucket with the greatest possible accuracy and in the shortest possible amount of time. S-curve motion control was used to run the stepper motor at the highest speed.

DIY PIKACHU CLOCK RADIO
(AUGUST, 2022)
Raspberry Pi Pico, FM Radio module, RTC module, Operational amplifier, Audio amplifier, PWM
This Pikachu clock radio can be used as a clock and FM radio, and it is equipped with an alarm function. The alarm sound (Pokemon Theme) is created by a PWM pin of Pico. A dual op-amp MCP 602 is used to combine two signals: alarm sound and radio. An audio amplifier, LM386, amplifies the combined signal with a gain of 20.
The circuit schematic and PCB were designed using KiCAD. The enclosure (3D modeling) was created in SolidWorks.
​
SMART PUSHUP MACHINE(SPUM)
(OCTOBER, 2018)
Bluno Nano, load cell sensor, IR distance sensor, Bluetooth
I developed a pushup device that helps the user build muscles in the most effective way. The pushup machine communicates with a smartphone app on Bluetooth. When the user selects a muscle group to improve, the SPUM app calculates the best SPUM device width and instruct the user to set the device width. Then, the app shows the pushup counts calculated by the device. This project won a second place in Engineering Festival at Inha University in 2018 which sent me to Taiwan to introduce this project in 2019.

TRAFFIC LIGHT SYSTEM USING RTOS
(FEBRUARY, 2023)
STM32F4 Discovery Board, FreeRTOS, Shift register
The TLS simulates vehicle traffic on a one-way, one-lane road with a simplified intersection that has a single traffic light. Detailed information can be found in the video link below. The system is built based on Real Time Operating System (RTOS)
​
DIY WAV. FILE SPEAKER
(MARCH, 2018)
Arduino Mega, SD card reader, speaker, LCD, DAC.
When a WAV formatted song is saved in the SD card, the song plays perfectly through the loudspeakers.
Basic sequence: wav file(signed 16 bit PCM) data are decoded to two 8 bit PWM signals. The digital signals are converted to analog signals by Class D amplifier and a simple low pass filter.
The speaker hardware (pac-man ghost) was created by a 3D printer.
​
LINE TRACER (APRIL, 2019)
Arduino Mega, stepper motor, light sensor, PID controller, low-pass filter
After learning about the PID controller, I made a line map using electrical tape to apply the controller. The line tracer hardware was created by a 3D printer. The robot has total 6 light sensors to detect the line. PID controller was used to control the speed of the motors steering the robot to travel along the line smoothly. Low-pass filter reduces noise in the light sensor data.
​
DIY FINGER FLICK POWER TESTER
(DECEMBER, 2021)
Arduino Mega ADK, load cell sensor
I made a DIY finger flick power tester using a load cell amplifier.
Once the tester is ready, the five LEDs in the middle will blink. When the button is pressed, the three red LEDs will blink by order. The user should flick his/her finger at the hitting zone when the last led turns off. The LEDs in the middle will show the result.
​
DIY ROBOT SOCCER
(FEBRUARY, 2018)
Arduino Nano, RF, joystick, DC motor.
Fun robot soccer game made by Evan Lee. Each robot consists of a transmitter and a receiver. The transmitter includes a RF module, a joystick and an MCU. The receiver consists of an MCU, an RF module and two DC motors.
​
DIY PINBALL GAME
(FEBRUARY, 2018)
Arduino Uno, 2-axis magneto-resistive sensors, DC motor.
This is new fun entertainment. The pinball machine was made to encourage me to exercise. Unlike normal pinball machines, this machine does not have any buttons to control flipper bats. To control the flipper bat, the user has to move two long sticks. The sticks have a compass module on each stick. When the user shakes the left stick, the compass module on the stick senses the movement of the left stick so that the left flipper bat moves.

AWARDS
1ST POSITION IN UVIC OCEAN CHALLENGE (DECEMBER 2023)
My team had 5 members and we made a real-time water quality monitoring system. My responsibilities were circuits and C++ coding of MCU.
The Beacon magazine wrote an article about our project.
2ND POSITION IN ENGINEERING FESTIVAL IN INCHEON, KOREA (OCTOBER 2018)
I was a leader of a team of 4 members. We made a smart push-up machine. My responsibilities besides team management were circuits and  C++ coding of sensors and Bluetooth.Â
This award offered us an opportunity to present the technology at the International Vertically Integrated Projects (VIP) Conference in Taiwan.
PROJECT AWARD IN FIRST LEGO LEAGUE KOREA (JANUARY 2011)
We made a smart monitor that reminds the user to blink their eyes and stretch their body to keep their body healthy.
