                  Make a simple indicator for your board Hi, I am Md Yeamin Islam Ashique Today i will share a little thing.Many people know that already. But who is starting now electronics. It's very good for his/her. You have to know what is indicator  ? Electricity is there or not for this check we are using indicator. After switch off also it will light.But i will make a indicator from a led (Light Emiting Died). But how can i light a led with 220 Volt ? It's too easy and simple. Generally we are using for a led a 3.8 volt dc battery that's simple. But from 220 volt ?You need to use some techniques. Needs Red,Blue,Green Or Any Color Led . Any Rectifier Died. 22K half watt resistance .  Now Follow The Picture  Make a simple indicator for your board Make a simple indicator for your board Set The LED Where you need.
