Autonomous Line-Following Robot

Started with a breadboard. Ended with a robot that follows a line at speed.

What I built

• PID controller in C++ tuned against encoder feedback
• Multi-sensor IR array for robust detection across different line widths
• Bluetooth module streaming live telemetry during test runs
• Motor driver circuit, wired and soldered by hand

Stack

C++, Arduino, IR sensors, encoder modules, Bluetooth serial.
