ESP32 PWM Tutorial: Controlling the Brightness of LED Pulse Width Modulation (PWM) is a technique that varies the width of a pulse while keeping the wave frequency constant. The PWM technique mainly used to control the brightness of the LED, speed of DC motor, controlling a servo motor, or in other cases, where have to generate an analog signal using a digital source. We explained the PWM in detail in the previous article.… |

Stereo Audio Pre-Amplifier Circuit with Bass and Treble Control using Transistors Often times, we need to control bass, treble, and volume of our audio signal before passing it through amplification stages to prevent sound distortion. The circuit that amplifies the audio signal before it enters the main speaker amplifier is called an Audio Preamplifier. The use of an audio pre-amplifier ensures good audio quality and provides options to modify our sound… |

Calibration of Ammeter, Voltmeter, and Wattmeter using Potentiometer We know that voltage, current, and power are measured in volts, amps and, watts and voltmeter, ammeter, and wattmeter are used to measure these parameters. Though these measuring instruments are manufactured with the care they may still give error readings at the customer end. So these instruments are calibrated to minimize the error. Here in this article, we will explain… |

How to Build a DIY Digital Oscilloscope using STM32 Microcontroller An oscilloscope is the one instrument every electronics engineer reaches for when a circuit misbehaves. A multimeter tells you a single number, but an oscilloscope shows how a voltage changes over time: the shape of a PWM signal, the bounce of a switch, or the ripple on a sensor output. Bench oscilloscopes are expensive, though, and the best way to understand how one… |
