This is daylight sensor switch circuit, for control load turn on when have sunlight. use simple circuit LDR,transistor,relay and can use with 12V supply
the Automatic LED solar Light is version 2. It has a higher performance, is brighter, compares the version 1. Because we use LED grow use a 12V battery
The AC light dimmer circuit can control light bulb or speed AC motor, we use triac and SCR as main,and adjust potentiometer and switch,more circuits
lets to see Automatic Op-amp night light circuit using IC-741. It is also very simple. As my feelings It has high sensitivity more than one,high accuracy.
This is the automatic night light circuit system with LED display, and from battery power. Because not convenient plug So charging system with solar cell
We try to apply a JK Flip-Flop to Light sensor switch circuit experiment. We use MC14027 or CD4027 or TC4027 as CMOS-IC that inside has JK-Flip-Flop, and 16 pins. Which each pins difference acts as show in Figure 1 As left section,first include of pin 1 to pin 7, and …
This is Simple light controller circuit that is controlled light-activate. Which use the inverter gate IC-40106 as main components in compare and controlled switches, and common phototransistors as sensors The Operation of switch has several forms. The most basic way is to press the switch directly. If modern must be …
