Raspberry Analog Signal in Circuit 1 Rotary Angle Sensor

Analog Signal

Analog signal refers to the electrical information represented by continuous physical quantities. The amplitude and frequency of the signal change continuously with the change of time. In electronics, we use sensors to measure the data of light, humidity, temperature and other physical quantities, obtain the numerical changes over a period of time, and use electrical signals to simulate its numerical changes. For example, when a sound signal is received by a microphone or other sensor and converted into an electrical signal, the voltage directly reflects the volume, and the frequency (tone) of the sound is directly converted into the frequency of the electrical signal. This is the meaning of the word "analog" in the analog signal.

Of course, an analog signal also has the difference between input and output, but unlike a digital signal, the input analog signal can not be directly used by Pico.
