Ultrasonic Sensor Without Arduino using 555 timer

Hey folks, have you used an ultrasonic sensor in your projects! Do you know how it works? In this project, we will use an ultrasonic sensor without Arduino for object detection. We will interface ultrasonic sensor with a 555 timer to control a DC motor. How ultrasonic sensors work? As the name suggests an ultrasonic […]

Voltage controlled oscillator circuit using LM566 VCO IC

Voltage controlled oscillator circuit is an electronic oscillator circuit whose output frequency is controlled by an input voltage source. By varying the input voltage, we can change the output frequency. A voltage controlled oscillator can produce frequencies ranging from few Hertz to tens of Gigahertz. Voltage to frequency converters is used in frequency modulation FM […]
