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 time, I will try to run and debug the LED blinking using the Raspberry Pi Pico 2 and Raspberry Pi Debug Probe provided by the Raspberry Pi development team. I will use Ubuntu for building and ...

This is a flashing led lights circuit powered from a 12V DC power supply that uses the well known 555 IC. Flashing lights have many and varied applications in life. They are used as warning lights on ...

Have you tried your hand at circuit sculpture yet? Well, if you were waiting for the ideal first project with a great build video to go along with it, keep reading. [4dcircuitry]’s 555-based flashing ...

Researchers say sensitive data can be extracted from air-gapped networks via a wireless router’s blinking LEDs. Researchers have uncovered a new data extraction hole inside air-gapped networks that ...

The eyes may be the window to the soul, but the blinking LED lights on a modem are more forthcoming, two researchers revealed this week in a proposed submission to a security journal. Joe Loughry, an ...
