Nowadays, single-color and multi-color flashing LEDs are easily available, which obviates the requirement of external chips to produce fascinating lighting effects ...

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 ...

You know how it is. You’ve got that new project running, and while it doesn’t consume much power, it also doesn’t give much indication of whether it’s functioning or just sitting there with a dead ...

A flashing LED? What is so special about that, you may well ask yourself. A microcontroller plus a handful of discrete parts, and Bob's your uncle – isn't it? Still, many readers love analogue ...

A flashing LED? What is so special about that, you may well ask yourself. A microcontroller plus a handful of discrete parts, and Bob's your uncle – isn't it? In harmony with the emphasis on analogue ...
