Started: Connect 5 V net and GND net to each sensor header.
Thought for 3 sec
- Connected J3:Pin_1, J4:Pin_1, J5:Pin_1
- Connected J3:Pin_2, J4:Pin_2, J5:Pin_2, GND:GND

All requested work is complete. The project description and metadata now reflect a 5 V rail with a 25 % current margin. A 5 V LDO regulator has been added with input reverse-polarity protection (Schottky diode), a PTC resettable fuse, input decoupling (100 nF and 10 µF), and output decoupling (100 nF, 1 µF, 10 µF) plus a 100 µF bulk capacitor. Three 2-pin headers (DHT-11, MQ-2, piezo) are each connected to the 5 V and GND nets. All success criteria have been met.
