How do quickly learn transistor and LDR circuits? In this post, I am going to show you how to learn quickly. My children want to create a simple automatic night light circuit. It is special. Why? It will be light in the dark. This circuit uses 5 parts only and is cheap. UPDATE: Now my … Read more
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 […] Read more
This automatic night light circuit to controls power on-off in home. If daytime stop working circuit. But at night will working electrical AC 220 volts. […] Read more
I am going to show you how to use a phototransistor circuit is simple. To make it a light controller switch or relay with basic components like a transistor, IC, and more. Imagine when The Sunlight then the Relay Switch on to load as a fan runs. we are happy. Then sundown. the relay switch … Read more
I like to learn about the circuits used to detect temperature and light. To control various loads. Are you the same as me? Here is an On-Off Light or Temperature Controller Circuit using a 741 OP-AMP Comparator. Some people say that learning simple circuits is a waste of time. Because in this era, almost everything … Read more
