What is sensors and actuators?
Quick answer
Sensors convert something physical, such as light or distance, into data a computer can read. Actuators do the reverse, turning a computer's decision into movement or output.
Students wire, calibrate and debug their own sensor rigs rather than using pre-built kits alone.
In context
Together they are the boundary between code and the physical world, and understanding that boundary is what separates a working build from a demo that only works on the bench.
Calibration, noise and tolerance become real problems the moment students leave the simulator.

Students wire, calibrate and debug their own sensor rigs rather than using pre-built kits alone.
