Some 1.5 v LED flasher circuits are available on the internet and we like to present you four of them. The flasher circuits below operate on a single 1.5 volt battery. The circuit on the upper uses ...

The article is being published in collaboration with JLCPCB. They supply high quality PCBs at a very reasonable price. They also can provide SMT circuit assembly. We ...

The purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...

LED chaser lights (or) sequential LED flasher circuit on a breadboard using 555 timer + 4017 IC and a few other components. The LED’s chasing rate can be adjusted using a potentiometer in place of 47K ...

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...

The small circuit shown here could act as a power indicator for the 230 V mains supply and in terms of efficiency is the equal of classical neon bulbs. Note first that the LED in this circuit flashes ...

There are dozens of LED flasher designs on the web. But this design is based on a special complementary transistor combination (which is not a PUT). To be honest, the following circuit was the result ...

Ordinary LED flashers turn the LED on and off abruptly, which can get a little irritating after a while. The circuit shown here is more gentle on the eyes: the light intensity changes very slowly and ...

In small towns, there are no traffic lights and the police regulate the traffic with hand signals. Since their hand signals may not be visible at night, it is necessary to have some illuminated ...
