Flashing a pair of LEDs at a rate of about two 'blinks' per second, this project is a neat toy that teaches a great deal about electronics. The circuit is basically an astable multivibrator or free-running oscillator, and as such it is one of the more popular types in use today. Educational and entertaining too! What you will learn: * Free-running oscillators * R/C timing circuits * Switching transistors * LEDs
