This is a simple blinking led circuit powered from 220V that can be used to mark special places or as voltage indicator. The voltage from the mains charges the capacitor through R1 resistor and D1 ...

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and ...

This simple and cheap circuit is not just for Christmas! There are just two resistors, a small-signal transistor such as a BC547, one ‘flashing’ LED and a string of ‘normal’ LEDs.

A simple circuit, but it just goes to show that we tend to forget the simple solutions in a world where a computer costs less than a dollar. Of course, you can get a chip whose sole purpose is to ...

The ' Raspberry Pi Pico 2 ', which was released on August 9, 2024, is equipped with the ' RP2350 ', a proprietary microcontroller equipped with an Arm core and a RISC-V core. The RISC-V core was ...

Since they would be making the invitations themselves, [Bill] and [Mara] needed a simple circuit that could be easily mass produced. They turned to the classic microcontroller-powered blinking LED ...

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