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 ...

Here is the circuit diagram of Two Flashing LED’s for different applications (such as model construction), and recreational. Having adjustable flashing speed with two potentiometers. It is the ...

The core of the dual flashing LED circuit is based on the 555 Timer IC configured in astable mode. In this mode, the 555 Timer continuously oscillates between its high and low states, generating a ...

The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.

Never miss a blown fuse again! This ultra-simple four-component circuit ensures you’re instantly alerted when a mains fuse fails, using an active flashing LED — no complex measuring needed, just smart ...
