Adjustable Single/Dual LED Flasher Using 555 Timer IC

PCBway: only $5 for 10 pcbs from https://www.pcbway.com/?from=CZcouple

The 555 timer IC is an integrated circuit that is used in a variety of timer circuits, pulse generators and oscillator applications. The heart of the tutorial is the 555 timer IC that is wired as an astable multivibrator.

In this tutorial, I'll first blink "an LED" using the positive pulse generated by a "DIY 555 Pulse Generator Module" (video: https://youtu.be/bMAnipPOjFo), followed by "two LEDs" alternating and flashing at a regular interval. The output frequency of pulses can be adjusted using a potentiometer. The circuit can be operated from any voltage between 5 to 15 volt DC.

Watch this video for detailed step by step instructions on how to build this circuit and for a complete instruction on how the circuit works.
