This project demonstrates a simple LED flasher/blinker circuit using a 555 timer IC in astable mode. It's ideal for electronics beginners and includes PCB design files, a schematic, and a bill of ...

This project demonstrates how to build a simple LED flasher circuit using the popular 555 timer IC in astable mode. The 555 timer generates a square wave output that turns the LED ON and OFF ...

These days, if you want to flash some LEDs, you’d probably grab a microcontroller. Maybe you’d go a little more old-school, and grab a 555. However, [Jacob] is even more hardcore than that, as ...

Looking for a mains switch inthe dark is easier if the switchcontains a built-in neon or filamentminiature lamp. Adding a small indicatorto any mains switch is helpful. It iseven better if the ...
