The humble NE555 has been around for over five decades now, and while during that time we’ve seen a succession of better and ...

This circuit can flash three sets of LEDs with different levels of Flashing. It can be used as Ornamental displays. The circuit uses a simple Astable multivibrator built around the popular timer IC ...

This is a project circuit in which we use PWM to dim the intensity of light of the LED. The Pulse Width Modulation (PWM) plays an important role in controlling the circuits. If you want to control the ...

Ultrasonic levitation — the practice of creating a standing wave between two ultrasonic sources and positioning lightweight objects such that they can float in the pressure minimums between them — has ...
