day-night on/off switch circuit diagram
>Day night on/off switch circuit diagram
This circuit is built using timer IC 555. It is a circuit running
from 9 to 15 volts DC. In this circuit, a 20K variable resistance is
used to adjust the desired level of day and night. And LDRs have
been used as night and day sensors. And a diode 1N4007 is used to
protect ic from high voltage.
And it is also very easy to make and the list of components used in this
circuit is given below.
