Day 16 — 4-Level Battery Indicator Module | 30-Day PCB Design Challenge Day : 16 / 30 Topic : 4-Level Battery Charge Indicator Tool : KiCad Category : Power Management / Indication

Project Overview A 4-level battery charge indicator PCB designed as Day 16 of the 30-Day PCB Design Challenge. The board visually represents the state of charge of a battery across four discrete threshold levels using the LM3914 dot/bar display driver IC, driving four LEDs that illuminate progressively as battery voltage rises. The design requires no microcontroller — the LM3914 performs all voltage sensing and…
