System and method for encoding and decoding serial signals formed by a plurality of color lights

A system for encoding and decoding serial signals formed by a plurality of color lights, comprising:

• an encoding device having a first memory, a first microcontroller unit, a multi-color driving circuit and a multi-color LED, the first memory used for storing at least one first serial code set therein, the first microcontroller unit electrically connected to the first memory for reading out the first serial code set and then generating a control signal corresponding to each of codes in the first serial code set, the multi-color driving circuit electrically connected to the first microcontroller unit for receiving the control signal and generating a driving signal corresponding to the control signal, and the multi-color LED electrically connected to the multi-color driving circuit for receiving the driving signal and generating various color lights having different wavelengths and flash time intervals corresponding to different driving signals;
• and
• a decoding device having a multi-color sensor, a second memory and a second microcontroller unit;
• the multi-color sensor used for detecting the color lights emitted by the multi-color LED and generating a detecting signal corresponding to the color lights, the second memory used for storing at least one second serial code set and a decoding procedure therein, the second microcontroller unit electrically connected to the multi-color sensor and the second memory, respectively, for receiving the detecting signal generated by the multi-color sensor and decoding the detecting signal via the decoding procedure stored in the second memory to obtain the first serial code set followed by determining if the first serial code set is identical to the second serial code set stored in the second memory, and in a case that the second microcontroller unit determines that the first serial code set is identical to the second serial code set, the second microcontroller unit sending an actuation signal.
