Light strips with terminal blocks for external expansion
Mode 1 uses the analog value of the photoresistor read by the ADC to adjust the brightness of the light strip.
Mode 2 uses an adjustable resistor/potentiometer to adjust the brightness of the light strip.
Mode 3 uses buttons to control the flashing speed of the light strip for flow mode.
Mode 4 is used to adjust the setting mode. The clock
digital tube displays hours and minutes, and the first three digits display the current mode.
