Q:How to use the microcontroller switch to control the length of the circuit section time

Use the timer inside the microcontroller to determine the time; use the microcontroller IO control port, to control the circuit off. Look at your question is the need for a clock chip DS1302 DS12C887 or PCF8563 like the RTC. MCU from the clock chip to read the current time, and you have to control the time contrast, you need to control the time, turn off or open the control circuit
