230V LED Indicator circuit

This is very useful schema for you.You can use this schema as a current indicator.The special thing of this schema is this schema operates 110V to 230V.I myself have use this schema for my door bell.so visitors who come home at night can easily see the door bell.you your self think different way and do something newly






Parts

R2 = 1M-1/2W
R1 = 470R-1/2W
D1 = 1N4007
D2 = 1N4007
D3 = 1N4007
D4 = 1N4007
D5 = 5mm. Blue LED
C1 = 220nF-275vAC


Note

# When you deal with 230V be careful.If you are too little Dont try this schema

#Use Quality parts.Specially think about the W of your parts

230V 110V simple Multivibrator Wiring diagram Schematic

Most of guys asked about 230V flashing diagram so I suppose this would be the most easiest schema diagram.Here we have used common multivibrator schema and two 3V relays.You can connect your AC line via the relay.( Use relay as a switch) Even the persons who use 110V can use this schema.Not only that If you like to attach this schema for you car you can  attach 12 v to the relay (as a switch).This schema can be operated with 3V power supply.

Note: 

# Dont supply over 4V 
# Find best relays 
#Build this schema on a PCB
