Simple Knight Rider lights Circuit for model cars
This simple circuit drives 6 LEDs in 'Knight Rider scanner mode'. Power consumption depends mainly on the type of LEDs used if you use a 7555 (555 CMOS version).

RGB Lights Circuit Diagram
The overall effect produced by this project is a glowing sequence of lights changing slowly from one colour to the next. The microcontroller cycles through randomly generated values of red, green and blue hues of light to produce a variety of nice colours. The software implemented on the controller interpolates from one shade to another, each colour channel being treated independently. Light intensity is controlled by means of pulse width modulation (PWM) for each colour. A high frequency of approximately 60 Hz is used to modify the light intensity and eliminate any flicker that might arise. RGB Lights Circuit Diagram One major problem that had to be over-come was unequal brightness of the LEDs used, the result of which is a tendency for one particular colour to dominate in the overall hue produced. It was found that blue LEDs are perceived to have the largest intensity and green, the lowest. This was compensated for by using a large resistor for blue and a low resistor for green, tog...
Game Show Indicator Lights Whos First
The circuit below turns on a light corresponding to the first of several buttons pressed in a "Who's First" game. Three stages are shown but the circuit can be extended to include any number of buttons and lamps. Game Show Indicator Lights Circuit Diagram: Three SCRs (silicon controlled rectifiers) are connected with a common cathode resistor (50 ohm) so that when any SCR conducts, the voltage on the cathodes will rise about 7 volts above the voltage at the junction of the 51K and 1K ohm resistors and prevent triggering of a second SCR. When all lamps are off, and a button is pressed, the corresponding SCR is triggered due to the voltage at the divider junction being higher than the cathode. Once triggered, the SCR will remain conducting until current is interrupted by the reset switch. Or, you can just turn the power off and back on. A 50 ohm, 5 watt resistor was selected to produce a 10 volt drop at 200 mA when a single 25 watt lamp comes on. Higher wattage lamps would ...
Fluorescent lamp lights starter
Why fluorescent lamp light blinking before long? Because Fluorescent light removes electrons and hit the wall of a glass tube coated with phosphors that emit light plastic. To throw a flow of electrons in the metal out in need of very high voltage electricity. Because not enough to voltage that we use 220 volt, fluorescent lamp starter, grafted on to stop a while to produce electricity in a high electric voltage. Fluorescent light starter component's High-voltage electric is cutt off from current to flow. Therefore, when Fluorescent Lamps, electrical connecting repeatedly cut, so look at our eyes blink, while starter is generally light but, when the lights go out starter that is lit exactly goes on.
Project of Car Head Lights Turn Off Circuit Diagram
This circuit when setup in a car automatically turns off the head light after a preset time after the ignition switch is turned off.So you can walk out easily from the dark garage in the light of your car. Car Head Lights Turn Off Circuit Diagram Car Head Lights Turn Off Circuit Diagram When the ignition switched on first the voltage from battery is fed to the relay through diode D1.When the ignition switch is turned off it produces a negative going pulse at the pin 2 that triggers the timer. The output of the IC goes high for the time set by R1 .This makes the transistor Q1 to conduct to energize the relay to drive the headlight.After the set time the light goes off.With the value of components used you can make a setting from 10 S to 60 S. Notes : Assemble the circuit on a good quality PCB or common board. Fit the potentiometer on somewhere on the dashboard so that you can easily set the timing.
Easy Make a Electronic Circuit Project Lights On!
This is a simple Electronic Circuit Project for light on circuit. This circuit ensures that you will never again forget to switch on the lights of your car. As soon as the engine is running, the dipped beams and the sidelights are automatically switched on. The circuit also causes the dipped beams to be extinguished as soon as the main beams are switched on. As you can see from the schematic diagram, no special components are needed. When the engine is running, the alternator will generate a voltage of more than 14 V. Diode D1 reduces this voltage by 5.6 V and passes it to the base of T1 via R1. Due to the resulting current, T1 conducts. The amplified current flows via R3, the base of T3 and D3 to ground. This causes T3 to also conduct and energize relay Re1. Lights On Circuit Diagram : If the driver now switches on the main beams, a current flows through D2 and R2 into the base of T2, causing this transistor to conduct. As a result, the voltage on the base of T3 drops, causing T3 ...
