This is very useful circuit for you.You can use this circuit as a current indicator.The special thing of this circuit is this circuit operates 110V to 230V.I myself have use this circuit 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 Don't try this circuit
#Use Quality parts.Specially think about the W of your parts
