555 timer IC is used here in astable operating mode which generates a continuous output in the form of square wave via pin 3 which turns the LED on and off. You can read here more about the different ...

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 ...

Blinking LED is the first step you would like to take to get started with electronics. In this tutorial we are going to connect an LED with ATmega32, which is an AVR series microcontroller. We are ...

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 ...

STM32F411CEU6 ("Black Pill" board or similar). Two LEDs (PA5 for blinking, PA8 for fading). Two resistors to protect LEDs. Jumper wires and breadboard for connections. Clone or download this repo.

The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.

This project is a basic flip-flop (astable multivibrator) circuit that alternately blinks two LEDs using two NPN transistors, capacitors, and resistors. The circuit uses capacitor charging/discharging ...

During festivals like Diwali, Christmas, and New Year strings of flashing lights are sometimes used to decorate homes and other premises. Arduino based flashing lights can be made with the help of ...

Never miss a blown fuse again! This ultra-simple four-component circuit ensures you’re instantly alerted when a mains fuse fails, using an active flashing LED — no complex measuring needed, just smart ...

This time, I will try to run and debug the LED blinking using the Raspberry Pi Pico 2 and Raspberry Pi Debug Probe provided by the Raspberry Pi development team. I will use Ubuntu for building and ...
