the digital tube. The correspondence depends on the order in which you send the data when you wire and write the code. DS is a serial input pin, so-called serial is to make the data on a signal line in order to transmit one by one, like a string of candied fruit. This pin we received from the Raspberry Pi at any one of the Gpio ports (output mode). The
