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 practice to get 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.

PT2262 is a remote control encoder paired with PT2272 using CMOS technology. It encodes data and translates address pins into a suitable serially encoded waveform for RF or IR modulation. The PT2262 has up to 12 tri-state address pin bits to provide up to 531,441 (or 312) address codes; thereby, greatly reducing any code conflicts and the possibility of unauthorized code scanning. The internal functional block diagram is as follows.
