We transformed the TM4C123 into a playable digital piano supporting real-time and auto-play modes. Tones are generated using a 64-sample sine table through a 6-bit R/2R DAC with SysTick timing at 16 MHz. PD0–PD3 map to keys C–F; SW1 toggles Piano/Auto-Play and SW2 changes octave or cycles songs. A speaker driven by an LM386 delivers clear notes across 3+ octaves.
Built a Bluetooth-driven robot car controllable via smartphone/PC. Implemented UART command parsing, PWM motor speed control, and GPIO direction outputs. Two modes: Demo and Manual for flexible operation.
Microcontroller game engine driving a Nokia 5110 LCD for graphics and R2R/amp for audio; focus on timing, input, and rendering loops.
Intrusion detection using ultrasonic range sensing on the TM4C123, with UART status output and protected voltage measurement via divider.
Gravity-based orbital simulation visualized in vPython; explore parameters like mass, velocity, and eccentricity.
Designed two synchronized embedded systems — a Smart House and a Stepper Motor Car — with stable ISR timing and filtered power control.
