Simple GUI Troubleshooting in Qt – Any Tips for Handling Sensor Input?
-
Hey folks! I’ve been building a basic GUI in Qt to visualize real-time sensor data (starting with ultrasonic sensors). I followed this great guide on interfacing the HC-SR04 sensor with Arduino:

I’m now trying to replicate the concept in Qt (reading distances and displaying them smoothly), but I notice the UI starts to lag when I increase the update rate. Has anyone here implemented something similar with proper signal-slot optimization or multithreading?
