Flashing LEDs without Arduino

Show you a great way to flash the led without an Arduino. I have used 555timer IC for this project. 555timer IC is used in a variety of timer, delay, pulse generation, and oscillator applications. So let's see how this IC works.

Supplies

We need,

  • Breadboard
  • 3.3v LEDs
  • 100 Ω resistor
  • Pot 500 kΩ
  • 4.7µF capacitor
  • 5v Power Supply

Turn on the circuit, and You will find that the LED blinks after some time. Now we know the design is right and everything works, try changing pot value and notice the effect on the flashing. The pot value can change the delay time of led.
