Analog LED Clock Circuit AT89C2051P

| 2008/11/08

301 LED Analog Clock Project Schema Files of PCB and C51 Compiler Source Code has been prepared by the C-in hex. The clock circuit is made of 301 LEDs with a diameter of 3mm forming fi = dial (the most one LED is in the middle), and 12 LEDs Stroke hours. The LEDs are arranged…

Lighting Circuit with White LEDs for Camera

| 2008/10/27

Prepared for a professional camera, I guess it fits many models. Also, there are examples of pictures taken with led lighting. The circuit works with 12 volts, the control IC HEF4538BP. Taking very close shots requires the right additional lighting to eliminate the shadow of the lens and gain depth of field by allowing the…

220V Led Flasher Circuit Simple , Transformerless

| 2008/09/09

There is a very simple flasher circuit transistor integrated 470k, 680ohm, 1n4007, 22UF, cardiac and led 470k resistor is not in my hand I used 560K Diac Wiki The DIAC, or “diode for alternating current”, is a diode that conducts current only after its breakover voltage, VBO, has been reached momentarily. When this occurs, the…

PIC16F84 king rider circuit

| 2008/09/05

In the early 1980s, the Led panel of the car named “Kit” in the K”nightRider” series became very famous, and many similar circuits were used in cars. A more advanced version of it was used in this project. A total of 32 LEDs are controlled based on the black lightning led effect circuit pic16f84 microcontroller…

Walking Led Light 555

| 2008/08/26

Our circuit was considered little different from the usual circuit. Different from the usual operation of the CD4017 circuit. Hopefully of interest to you. They remain in one direction lights are burning and burn progressing. Lighting sequence starts from LD1. Ie, starting from the beginning after burning LD16 LD1 goes out. P1 potentiometer to set…
