light activated led scr
The schematic presented is a circuit for a light-activated LED utilizing an SCR (Silicon Controlled Rectifier). SCRs, which resemble transistors in appearance, operate on different principles compared to transistors. In this circuit, the SCR functions as a switching device. When...
Battery charger or Power Supply 14 volt 4 ampere
The schematic diagram originates from a circuit designed as a battery charger/power supply with an output of 14V and a maximum current of 4A, utilizing the VN64GA MOSFET. This high-performance battery charger is specifically engineered for gelled electrolyte lead-acid batteries,...
WhirlyGIG
This project employs a technique similar to existing products, allowing for the continuous display of text using a high-speed rotor and a strip of LEDs. The term "WhirlyGig" is derived from the word "whirl," which means to spin, and the...
New Knight Rider LED Board
The TL082 (Or a TL072 also is OK) Creates an Adjustable Sawtooth Generator. (It also has a Square wave Output, but it isn`t used here.)
The Left and Right LEDs are connected in series, and if this circuit is used on...
6-Channel Running Light
The circuit of the running light consists of two integrated circuits (ICs), a resistor, a capacitor, and seven light-emitting diodes (LEDs), along with a decade scaler IC.
The running light circuit is designed to create a sequential lighting effect using seven...
line powered white leds
The LED circuit illustrated below features 25 white LEDs connected in series to a 120VAC power supply. This configuration can be adjusted to accommodate a different number of LEDs by modifying the resistor value. The specific resistance required will depend...
Three-year-led-flasher
Inserting two 1-MΩ resistors, R1 and R2, in the output stage of one of the circuit's inverters limits the current needed by the oscillator tone to more than a few pA. This circuit includes a CD4007 package, which contains three...
led light circuit schematics
This circuit should only be attempted by individuals with a strong understanding of electronic devices. It is connected to a main power source (220V) and poses a risk of high electrical shock.
This circuit operates at a mains voltage of 220V,...
Automatic Control for LCD Panel Backlight
This is an automatic LCD panel backlight control circuit. It is a simple, low-cost implementation of an LED controller that can compensate for aging effects.
The automatic LCD panel backlight control circuit is designed to enhance the performance and longevity of...
