• Calculated the minimum switching frequency for a converter to operate in CCM and validated the inductor current waveforms of the converter in PSIM

• The system utilizes an LPC802 microcontroller which interfaces with sensors, a heartbeat LED, a piezo buzzer and LED to give a visual and audio indication when the plant requires water or the plant is too hot
• Generated regular interrupts using a Systick timer and an interrupt handler to process and report temperature and humidity readings, ensuring the user is aware of parameters outside deadband
• Established and validated I2C communication with onboard temperature sensor using a… Show more

• Translated logical address’s to corresponding physical addresses, using FIFO TLB and page table, to output the value of the byte stored at the physical address
• Produced a Bash script in the Linux OS which copies program output to a text file and outputs deviation with expected test results, improving the ease of troubleshooting
• Assumed a smaller physical address space and modified program to keep track of free frames as well as implemented a page replacement policy using LRU… Show more

• Assumed a smaller physical address space and modified program to keep track of free frames as well as implemented a page replacement policy using LRU to resolve page faults when there is no free memory. Show less

• Ran scheduling algorithms written in C, within Linux and utilized a makefile to build and run each
algorithm with terminal user commands, reducing the compiling time
• Ordered processes from a text file in a LinkedList according to CPU burst and priority, reducing the complexity in calculating processing times

• Designed a C program to serve as a shell that accepts user commands and executes each command in a separate process.
• My implementation supports input and output redirection as well as pipe IPC between parent and child processes.
• This project involved the use of UNIX system calls : fork(), exec(), wait(), dup2(), and pipe().

• Designed schematic for arm, validated design on breadboard before prototyping and soldering on PCB
• Implemented manual motor control using servo library, TeraRern and code written in C++ to move motor based on keystrokes resulting in finer arm control
• Controlled 3 servo motors using PWM Arduino output allowing for maximum torque and quick response time

• Designed power supply using full wave rectifier and corrected output voltage using an oscilloscope
• Reduced Output Voltage Error to <10% using different combinations of resistors and capacitors to vary the mean output voltage and peak to peak voltage
