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 very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and ...

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 ...

Regular Hackaday readers will be familiar with the work of Boldport’s [Saar Drimer] in creating beauty in printed circuit board design. A recent work of his is the Widlar, a tribute to the legendary ...

An LED is commonly used as a "power on" indicator for many electronic devices. For the LED to produce discernible visible light in daylight, the forward-bias current needs to be in the moderate range ...

Recently I converted the parking lights/turn signals and the taillights/turn signals in my 1956 Chevrolet to LEDs. The good part is they are really bright; the bad part is now the turn signals won't ...
