This is Simple monitor turn on delay circuit, by use contact of relay acts as a switch. When entering an AC main to this circuit. The circuit will delay while Reduce the surge current protection with fuse. Read more
This circuit is formed maintain one’s position voltage from solar cell with , shunt regulator circuit. For protect voltage not too until much destroy battery. Because of something charger too much. The D2 be for protect current flow turn back from battery during nighttime. The circuit maintains one’s position current the few , for feed … 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
How to use ULN2003 stepper motor driver for microcontrollers, Arduino, PIC, MCS51, etc. It’s easy to use, small, and cheaper than transistors. 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
