The discussed Earth leakage circuit breaker diagrams will monitor the leakage current level of the earthing line of your house electrical sockets and will trip the appliances as soon a fault is detected. Here I have explained 2 designs, first using transistors only and the second using IC LM324. Introduction If anything goes wrong with […]

Make an LED AC Voltage Indicator Monitor Circuit
The LED AC mains voltage level indicator is a circuit that can be used for displaying and monitoring the instantaneous voltage level of any 220 V or 120 V mains home AC input, through a correspondingly rising and falling LED bar graph. A simple construction and accurate result are the main features of this tiny […]
