Purpose
A troubleshooting engagement for Mapua University, carried out entirely on the client side: diagnose and repair the Arduino firmware of an existing hardware prototype so the device could operate reliably without server-side intervention.
Description
The work centered on debugging two substantial Arduino sketches driving a multi-peripheral device — GPS and GSM modules over software serial, a DHT11 environmental sensor, battery monitoring, and an SSD1306 OLED menu interface. Issues were diagnosed and resolved directly on the client's hardware, restoring stable sensor readings, display behavior, and module communication while keeping downtime to a minimum.
