Light a LED using Main Current 230V/110V AC
To light a LED we cannot just connect it to mains Voltage. But if we really want to indicate AC voltage with a LED how are we supposed to do it. Adding a transformer or a Switch mode power supply and making a step down circuit will do the job but It is too much. So in this post I will show you how to light a led using only 3 components BE CAREFUL 230V can Kill You! This is the Circuit schematic This is the circuit with the most common types of LED indicators come with. The Diode 1n4007 is an essential part in this circuit. It helps to protect the led in the negative half cycle. any questions.Comment down below
