RX-8 LED
The circuit has been successfully recreated and functions properly when the line connected to the 1 µF capacitor of the "2" terminal of the running lights' LM7812 is not grounded. This line is also connected to the 33 µF capacitor...
using led as a light sensor
This circuit demonstrates the use of a standard LED as a light sensor. It utilizes the photovoltaic voltage generated across the LED when exposed to light. LEDs are more cost-effective than photodiodes and feature an integrated filter, which is advantageous...
Ring Counter Circuit Working Principle with Animation and Video
Digital counters have various applications in electronic circuits. In digital electronics, counters are utilized in different situations. This article presents the concept of a ring counter circuit, which functions as a register counter. An animation and simulation video of the...
LED Dimmer Lighting
A dimmer for individual LED bulbs. LEDs (light emitting diodes) are very sensitive components; exceeding their rated current or voltage can drastically reduce their lifespan from over 50,000 hours to mere microseconds. LEDs are current-driven, meaning that the intensity of...
Search Light Signal
This circuit controls a searchlight-type signal head and produces solid red, yellow, or green indications. The signals can be connected for normal or approach-type lighting of the green signal. The circuit utilizes an LM556 dual timer IC in a complementary...
LED or Lamp Pulser
This circuit operates a LED in pulsing mode, i.e. the LED goes from off state, lights up gradually, then dims gradually, etc. This operation mode is obtained by a triangular wave generator formed by two op-amps contained in a very...
io port programing chalange
This program is a simple Traffic Light Controller. Between the start time and end time, the system controls a traffic light with pedestrian self-service. Outside of this time range, the yellow caution lamp is blinking. The commands include displaying times,...
how to build bicycle back safety light
This circuit is designed to provide a clearly visible light using 13 high-efficiency flashing LEDs arranged in a pseudo-rotating order. Due to its low voltage, low battery drain operation, and compact size, the device is suitable for mounting on bicycles...
A passive light emitting diode output level indication circuit
A passive light-emitting diode output level indication circuit.
This circuit utilizes a light-emitting diode (LED) to provide a visual indication of the output level from a given source. The design is characterized by its passive nature, meaning it does not require...
