Sensor World: words to know

Teaching this? Open projector mode

Sensor — A part that reacts to the world — light, heat, motion. Sensors give your circuit 'eyes' and 'ears'.

Input — A signal coming INTO a part. Sensors and switches are inputs to gates.

Output — A signal going OUT of a part. In this game it can turn on a light or motor; real circuits may need a driver.

Temperature — How hot or cold something is. Temp sensors react to changes in heat.
