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 sensors and modules on hand, according to the concept of practice (hands-on try), for the purpose of learning and communication, I am going to do experiments one by one here, and will record them regardless of whether they are successful or not. It is a difficult problem, and I hope to be able to throw bricks and spark jade.
[Arduino] 168 kinds of sensor module series experiment (data code + simulation programming + graphics programming)
experiment 212: 9 in 1 multi-function expansion board DHT1 device temperature and humidity LM3 temperature 5 buzzer 1 compatible with UNO
Take the combination of "Arduino program code" + "Mind + graphics programming" + "Linkboy simulation programming"
Complement each other, lay a solid foundation, and promote understanding
