This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

This is a simple blinking led circuit powered from 220V that can be used to mark special places or as voltage indicator. The voltage from the mains charges the capacitor through R1 resistor and D1 ...

Evil Mad Scientist Labs brings us this easy to make LED blinking circuit. The idea is to put a LED in series with a small blinking incandescent bulb from a string of Christmas lights. The bulb has ...

They turned to the classic microcontroller-powered blinking LED circuit powered by an ATtiny13. The first order of business was producing 50 printed circuit boards for each of the invitations.

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use to turn on and off an external light like an led or relay for bigger loads.

Energy from the bus flows through the indicator circuit through a capacitive ground connection. This means when higher voltages exist, the air becomes slightly conductive, allowing current to flow ...
