First‑year BTech Electrical Engineering project (2020–21): NI Multisim simulation of a wearable stress‑meter with sensor‑fusion analytics.

An Arduino beginner project that demonstrates how to create an LED bar graph using multiple LEDs controlled by a potentiometer. The project uses analog input mapping to light LEDs in sequence, similar to a volume level indicator.

High-level Arduino library for controlling animated LED bar meters using MAX7219/MAX7221 or HT16K33 drivers. Ideal for prop-making, visual meters, and signal-driven lighting effects.
