CASE ANALYSIS
Scenario
Building a small RC car that follows a line using two IR sensor pairs and an Arduino to drive left and right motors independently.
Key decisions
- Use NPN low-side switching for DC motors with flyback diodes for inductive kickback.
- Model each IR sensor as an IR LED plus reverse-biased photodiode with a pull-down resistor.
When to reuse this
Reuse this netlist for Arduino-based differential-drive robots that need black/white line detection and independent motor control.
