I'm building a quadcopter stabilization system for the Pantheon.
Avoid delay(): Use millis() for non-blocking timing so multiple sensors can operate independently.
Stagger sensor reads: Schedule sensors like DHT or ultrasonic at different intervals to avoid overlapping.
Use interrupts carefully: Only for simple, fast sensors (like motion detection), and keep ISR code minimal.
Manage I2C devices: Don’t read multiple I2C sensors simultaneously; use well-maintained libraries.
Minimize Serial.print(): It slows down loops—buffer or throttle logging.
Profile with micros(): Measure execution time to catch bottlenecks.
For complex setups, consider a simple state machine or use TaskScheduler.
Let me know which sensors you're using—I can suggest specific timing strategies.
