How to connect LED to 220v for HOMEMADE pilot light / 110/220 VAC. In this video tutorial we will see how to connect an LED diode to the 220v home network, remember that to do this electronic project you must have minimal knowledge in both electricity and electronics, since we will be working with the mains voltage In this case for Spain 220/230v and it is quite dangerous, that being said, for this we are going to use an LED bulb, a home switch for 230v, a power cable that is recycled from any other electronic device or appliance, a red LED indicator diode , a 22k 2 watt electrical resistor, a 1 amp 1000v 1n4007 rectifier diode and we are going to install the light bulb with a switch, and then install the LED indicator diode, with this simple electronic project we can have an indicator light in each plug of the house or home and when we have the light off, it can tell us where the plug is, I also leave you the electrical diagram so that you can assemble it to your liking and I explain at the end of the video how the system works, it is a easy way to place indicator lights in the electrical installation of your house without spending a lot of money, if you like the video don't forget to leave your LIKE thank you..
