led-bar-graph

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

Arduino library for animated LED bar meters using MAX7219/MAX7221 (hardware or software SPI) or HT16K33 (I2C), with custom mappings and non-blocking animation queues.

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.
