Troubleshooting Guide

When something isn't working, don't just start changing code. Observe first, then figure out what's actually wrong.

Step 1: Run the Self-Test

Before assuming it's a code problem, run self_test.c. It will test each motor and servo one at a time. This rules out hardware problems quickly.

📊 Reading Sensors

// Digital sensors (touch, bumper) - returns 0 or 1
digital(port_number);  // Example: if(digital(0)) { ... }

// Analog sensors (light, distance) - returns 0 to 4095
analog(port_number);   // Example: if(analog(0) > 2000) { ... }
