This circuit is submitted by Mr. Seetharaman and its full credit goes to him. This is the circuit of a well tried and reliable 230 Volt AC mains operated 24 LEDs (super bright 50mA LEDs). While practically compare the brightness between this circuit and 11watts tube, the LED light is much better. Power LED Driver Circuit Electronics DIY Here's a really simple and inexpensive Power LED driver circuit. The circuit is a "constant current source", which means that it keeps the LED brightness constant no matter what power supply you use or surrounding environmental conditions you subject the LED's to. White LED Drive Circuit Cappels Be Careful About Peak Current. A note of caution: These LEDs are comparatively expensive, so I suggest putting a small resistor (1 to 10 Ohms) in series with the cathode of the LED and measuring the peak current as inferred from the IR drop using either a scope or a peak detection probe (as described elsewhere in these pages) while testing this circuit to be sure you don't exceed the ...

PARTS LIST How to Build an IR LED Circuit Learning about Electronics How to Build an IR LED Circuit. In this project, we will show how to connect an IR LED so that it emits infrared light. This is a very simple project, as all that is needed is to give the IR LED power. Flashing LED Circuit Electronics DIY Here's a simple circuit that flashes an LED on and off. This circuit uses the 555 timer in an Astable operating mode which generates a continuous output via Pin 3 in the form of a square wave. This turns the LED (D1) on and off. The speed at which the LED (D1) is turned on and off is set by the values of R1 and R2. UP DOWN FADING LED Circuit 555 Timer Circuits UP DOWN FADING LED Circuit A Circuit that fades an LED on and off. Overview These two circuits make a LED fade on and off. The first circuit charges a 100u and the transistor amplifies the current entering the 100u and delivers 100 times this value to the LED via the collector emitter pins. How to Build a Simple LED Driver Circuit How to Build a Simple LED Driver Circuit. In this project, we will show how to build a simple LED driver circuit. A LED driver circuit is a circuit which can power on and light an LED> Simple Blinking LED Circuit: 5 Steps (with Pictures) Simple Blinking LED Circuit: A very simple circuit that you can build to blink or flash LEDs. The circuit is built using transistors, resistors, capacitors, and LEDs. Of course you will need a breadboard, wire jumpers, and a power source. The parts list includes: PNP... Circuit breaker A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume ... RGB LED Strip Circuit With Arduino: 4 Steps RGB LED Strip Circuit With Arduino: This Instructable covers the assembly of a circuit capable of PWM ing (pulse width modulating) a 9 12v RGB LED strip and programming an Arduino to cycle through a range of colors. I will discuss how to mount a transistor to a heatsink & assemb...

Instead of pen and paper, it uses nine 10mm tri colour LEDs arranged in a 3 x 3 grid. Turn Signal Indicator Lights Motorcycle Led | Autolumination The Autolumination provides Turn Signal Indicator Lights Motorcycle Led with better style and high quality performance. LED Fade In Fade Out Dimmer PCB Heaven Here is the first circuit schematic that i designed, and i tried to keep it as simple as possible: Similar to the LED fade out dimmer, multiple LEDs can be connected in parallel with one resister per node.Again, you need to take into account the maximum ratings of the transistor before connecting a million LEDs. Simple LED flasher circuits Wild Bohemian LM3909 LED flasher chip. In the late 70s, National Simiconductor came out with the LM3909 LED flasher chip. Many of the electronics magazines made a big deal about it at the time, and I got one from Radio Shack, experimented around with it and concluded it wasn't such a big deal after all, although I did use the circuit in an LED flasher I took to my first Rainbow gathering. AMZ LED Popping Muzique Stop the LED Indicator Noise. This is the typical method to connect an LED indicator to a 3PDT switch used to bypass a pedal circuit. When the switch contacts are in the "up" position, the connection is made through the LED to ground and it will light up.
