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 ...

To make a perfect flasher light, we are using 2 pieces 68 KΩ resistor with the circuit. Now we make a parallel connection between this two resistor. We connect it’s parallel terminal with 7no leg of ...

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 – ...

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 ...

This simple Mock Flasher LED simulates the indicator of a sophisticated Alarm system. It can be placed in doors, gates and vehicles to confuse intruders. The circuit is too simple using a Unijunction ...

This is probably the simplest idea to generate flashing light from an LED using AC. The circuit is relatively the simple way of flashing one or more LEDs from a high voltage DC obtained from Mains.

LED flasher circuit 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 ...

Article A Self-Charging LED Flasher A Self-Charging LED Flasher The circuit is very simple: an ultra-bright green LED, two 10-MΩ resistors, two 100-nF ceramic capacitors and a push-button switch. When ...

Figure 2 shows the current-voltage waveform of the circuit. Here are a couple of other examples. For a 5-V, ±5% monitor, set R1 = 121 Ω and R3 = 301 kΩ.
