LED Amplifier Circuit

The light emission of an LED is usually fairly small. In case a lot more brightness is needed, the following LED amplifier circuit might help. The LED to be amplified’ is actually substituted by an LED in an opto-coupler that clicks a lamp (for instance, a signal lamp) attached to the mains supply. Once the […]

Simplest Strobe Light Circuit

A very simple strobe light circuit can be built using a single transistor and a high bright white LED, in conjunction with a flickering LED. As may be seen in the diagram, a simple single transistor driver is used for illuminating the strobe LED lamp, which is controlled by a self oscillating flickering LED connected […]

Car Chasing LED Arrow Turn Signal Indicator Circuit

A very simple yet interesting Chasing LED arrow car tun signal indicator circuit is discussed in this article. The circuit uses just a single 10 stage Johnson’s decade counter IC 4017 and an UJT for executing a very interesting two pattern LED light chasing on the connected LEDs, which produce an impression of creating an […]
