The reference to 37 sensors and modules has been widely circulated on the Internet. In fact, there must be more than 37 sensor modules compatible with Arduino. In view of the fact that I have accumulated some sensor and actuator modules on hand, according to the concept of true knowledge (must be hands-on), for the purpose of learning and communication, here I am going to try and do more experiments one by one.

code result
The analog value is read from the 10K potentiometer module connected to pin A0, stored in a variable, value = map(val, 0, 1023, since the ADC inside the Arduino is a 0-bit ADC, the analog reads from 179 to 10, but the RC servo motor can only rotate 0- so the function map must scale the scale from 1023-1 to 180-0, and then store it in val myservo.write(val); When 1023-0 is lowered to 179-0, the servo motor is then instructed to rotate to the val delay variable (1023); a delay of 0 milliseconds, thus allowing the degree of servo motor to be adjusted by rotating the potentiometer.
