Nite Rider LEDS
As a keen cyclist I am always looking for ways to be seen at night. I wanted something that was a novelty and would catch the motorists eye. So looking around at my fellow cyclists rear lights, I came up...
Led or Lamp Flasher Circuit
Ideal for operating 3 to 24V DC existing on-circuit lamps. This circuit was designed to provide continuous light for lamps already wired into a circuit.
The circuit is intended to facilitate the operation of existing DC lamps that are integrated into...
230V Blinking LED
A pulsating light is used for signaling purposes with a voltage of 230V. A simple circuit has been designed, consisting of an LED diode, two capacitors, two resistors, a diac, and a diode. The operation of the circuit is straightforward....
Two-LED Pilot Light
This circuit was designed on request and can be useful to those wishing to have, say, a red LED illuminated when an appliance is on and a green LED illuminated when the same appliance is off. Any mains operated appliance...
How to Make a Simple Reverse Forward LED Light Chaser Circuit Using IC 4017
An LED light chaser circuit is an electronic configuration designed to illuminate a group of LEDs in a predetermined sequence. A commonly used integrated circuit (IC) for creating this type of LED sequencer circuit is the 4017. This IC functions...
LED Voltage indicator
When the input voltage is 0 the LED glows. The LED stops glowing when the voltage rises to the level determined by R2. Reverse + and - pins to reverse operating mode. To set voltage at which LED goes off,...
LED outline display control unit cipher scheme on the basis of the one-chip computer
The LED guard-rail tube, also known as the decorative tube, is an advanced LED illumination product designed for decorative purposes. It utilizes red, green, and blue LEDs as light sources, employing microelectronics and digital technology to create color chasing effects,...
Automatic switch for batteries
Currently, batteries are becoming increasingly powerful, serving as the sole energy source for portable electronic devices. The rapid evolution of battery technology has prompted manufacturers of electronic equipment to strive for reduced power consumption in their products, enabling them to...
Running LEDs
This is a doorbell circuit featuring flashing LEDs for enhanced visual appeal. The NE555 integrated circuit (IC1) functions as a clock generator, configured as an astable multivibrator with a frequency adjustable via a potentiometer (VR1). The clock pulses generated by...
