The scenario
A line follower robot uses an ESP32 to read a 3-channel IR sensor array and drive two DC motors through an L298N H-bridge, powered by a 7.4V LiPo battery with a 5V regulator.
What is in this drawing
Read the decisions behind it.
01
Use L298N generic_ic with explicit pin roles for VS, VCC, ENA/ENB tied to 5V
02
Power IR sensor array from 5V to match ESP32 3.3V logic
03
Common ground all modules to 0 net
Reusable for any ESP32-based differential drive robot needing motor control and sensor integration.
