The flasher circuits below operate on a single 1.5 volt battery. LED flasher circuit diagrams The circuit on the upper uses the popular LM3909 LED flasher IC and requires only a timing capacitor and ...

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

LED flash requirements for machine-vision systems are far more demanding than what a standard PWM dimming driver can meet. That is, most high-end LED drivers are designed to produce PWM dimming ...

[Collin] demonstrates this technique in the video, constructing a simple LED flasher circuit. He says that the process works decently enough, and was kind of fun to do.

Chibitronics combines familiar adhesive stickers with bits of LEDs, sensor circuits, and even a programmable microcontroller, to create a playful set that educates while adding some flash to one ...

In Figure 1, National Semiconductor's LM3710, a supervisory circuit, is configured to reduce the power consumption of a traditional LED indicator by 99%.
