Inverters can also turn a daylight sensor into a night-light, as shown in
Figure 9.20
. The
daylight sensor emits a signal according to the amount of light it's receiving. Feeding this
into an inverter turns the lamp on when the sensor is off, and vice versa.

and noteblocks to create a full lighting system with an audible sound as night hits.

gate with three types of input, any of which can light the lamp.
