This is a project that is a basic alternating flashing LED circuit using no Integrated Circuits.

The Component List :

2 LEDs

2x 470 Ohm Resistor

2x 4.7kOhm Resistor

2x 47uF Capacitor

2x 9014 NPN Transistors

The Voltage range is 4V-9V

The YouTube Video for this project is here:

Step 1: Schematic

Here is the basic schematic for the circuit.

This is simple circuit to build and you can see in my YouTube video the circuit works well.

Step 2: Finished Project

You can see my finished project here.

This is my first instructable and hopefully there will be more projects to come on here and on YouTube
