MCU U3 pin 6 and MCU U3 pin 17 are connected to the +3.3V operating voltage. MCU U3 pin 6 is connected to color sensor pin 5 (INT), and MCU U3 pin 31 is connected to one end of resistor R9. MCU U3 pin 16, MCU U3 pin 32, the other end of resistor R9, and color sensor pin 1 (GND) are grounded. Pin 18 of the microcontroller U3, pin 19 of the microcontroller U3, and pin 20 of the microcontroller U3 are respectively connected to the RGB light-emitting board drive circuit, wherein pin 18 of the microcontroller U3 outputs a blue PWM signal to the RGB light-emitting board drive circuit, pin 19 of the microcontroller U3 outputs a green PWM signal to the RGB light-emitting board drive circuit, and pin 20 of the microcontroller U3 outputs a red PWM signal to the RGB light-emitting board drive circuit.
