Hello everyone, I am a small Editor.

Record the content in the previous section and click "open link ".

Today we will talk about sensors.

Today we will talk about light and ultrasound.

Start with a chart:

There are three optical interfaces:

UCC, out, And GND.

Ultrasonic has four interfaces:

UCC, T, E, And GND.

The following is the principle.

The ultrasonic wave emits an ultrasonic wave, and the sound waves rebound when they hit the object. The other side receives the ultrasonic wave to determine the distance.

The light sensation is the minimum 0 value of the detected light value, and the maximum 255 is determined.
