This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and make it a warning light for a forklift or even a turn signal light for a ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

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 ...

Almost every micro-based project that I have designed in the past 25 years has had a flashing LED, originally as a “health” indicator, but the feature has expanded to use as a status indicator where ...

What is it about pseudo random flashing LEDs that make us go gaga? We don’t know, but there’s definitely something there. [seligtobiason] has this obsession too. After seeing several more complicated ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...
