The best learning is Doing it. Imagine you can use your life is better with your own electronic project. And at the same time, you learn digital basics, flip-flop switch circuit. Using CD4027 JK flip-flip. It’s great, right? Let’s get started to see the two 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.
Automatically change the dark corner of the house to be brighter with LED. No AC main but can run with battery solar charger. Do not doubt that How does it work or is it easy? Let's learn.
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 [...]
The emergency light circuit will have battery backup charge to stored, But when electricity failure, it does opposite is battery will discharge into lamp
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 [...]
This is Simple light controller circuit that is controlled light-activate. Use inverter gate IC-40106 as main,controlled switches phototransistors as sensor
