It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

Often, HP laptops are configured to go into sleep mode, causing data stored in RAM to be temporarily moved to the computer's hard drive when the lid is closed on the device. This is the default ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

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 ...

Researchers say sensitive data can be extracted from air-gapped networks via a wireless router’s blinking LEDs. Researchers have uncovered a new data extraction hole inside air-gapped networks that ...

Raspberry Pi Pico 2 ' equipped with the proprietary microcomputer 'RP2350' was released on Friday, August 9, 2024, Japan time. The Raspberry Pi development team received the actual Raspberry Pi Pico 2 ...

You know how it is. You’ve got that new project running, and while it doesn’t consume much power, it also doesn’t give much indication of whether it’s functioning or just sitting there with a dead ...
