Bar-Mode Lights Sequencer
The terminal of R7, indicated by an arrow, must be connected to the desired output pin of IC2 or IC3 to select the number of LEDs or clusters that will form the bar. For instance, to drive seven LEDs or...
Mains Blinking LED
I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of the circuit is extraordinarily...
home-garden-light-led
Currently, white LEDs are available that emit a significant amount of light. Their brightness is such that direct eye contact should be avoided. Although they are still relatively expensive, this is expected to change in the future. A highly effective...
220V Flashing LED Circuit
An AC mains operated single LED flasher circuit is constructed using the widely utilized CMOS timer chip TLC555. The entire circuit is powered directly from the 230VAC grid supply via a capacitive potential divider and associated components. This compact LED...
40 segment led s meter
Provide your radio with an actual cord signal. First, adjust the HIGH LEVEL potentiometer to the point where all LEDs are illuminated. Then, completely remove the signal and adjust the LOW LEVEL potentiometer until no LEDs are lit. If the...
Mains Powered White LED Lamp
An array of white LEDs can serve as an effective small lamp for the living room. LED lamps are commercially available.
LED arrays are increasingly popular for providing ambient lighting in residential spaces. The use of white LEDs in a lamp...
A 12 Volt Switching Power Supply
This circuit is designed for individuals needing to boost or drop a voltage. The output operates at high frequency but can be rectified and filtered to provide a DC output. When rectifying high frequencies, it is essential to utilize high-speed...
MAX668 16V 4.4A switching power supply circuit design electronic project
A simple 16-volt switching power supply circuit can be constructed using the provided diagram, which is based on the MAX668 constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controller. This integrated circuit is designed for a wide range of DC-DC conversion applications...
Bicycle back Safety Lights
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...
