[Diao Ye learns programming] Arduino hands-on (116)---five-way navigation button module

The reference to 37 sensors and actuators 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 practicing true knowledge (must be done), for the purpose of learning and communication, I am going to try a series of experiments one by one, regardless of success (the program goes through) or not, They will be recorded - small progress or unsolvable problems, hoping to inspire others.

Five-way tact switch

Also known as multi-function switch or multi-line switch, switch operated in five directions, six-pin with positioning column, patch type, this series has multiple specifications: 10 10 5, commonly known as positive five-way switch, 7*7, commonly known as oblique Five directions, various heights are optional.

The biggest difference of the five-way switch is that it has five contacts. That is, at the inner bottom, there is a central fixed contact and common contact housing, and there is a housing around which there are many peripheral fixed contacts. These housings are placed on movable contact springs. When the machine wants to form a path, it can directly connect the contact spring and the common contact together. The movable contact reeds can be connected together, together with the control of the operating rod, one movable contact reed can be directly connected to its corresponding contact.

The five - way navigation key module is equivalent to 7 independent key switches. One end of the 7 switches is connected to the common
terminal
COM . ——Left” direction key “ RHT—right” direction key “ MID—middle” direction key SET ——“Setting” button RST——“Reset” button output——digital level (press low level, release high level)
