In a previous article, I have shown you how you can build your own switched capacitor voltage converter circuit using the classic industry-standard LMC7660 IC. But oftentimes there are situations when you don’t have a specific IC available or the cost of an additional IC is ruining the harmony of your BOM. And this is where our beloved 555 […]
A rectifier is a circuit that converts alternating current (AC) to Direct current (DC). An alternating current always changes its direction over time, but the direct current flows continuously in one direction. In a typical rectifier circuit, we use diodes to rectify AC to DC. But this rectification method can only be used if the input voltage

Sometimes, we might need an AC bulb flasher circuit that can blink a series of bulbs in a particular time interval for decorative purposes. By controlling the flashing time interval and sequence, we can make a series of bulbs look beautiful for outdoor decoration in Cafeteria, Restaurants, etc. or even used it for heavy Christmas light decoration,

A crude way to power your DC circuits with AC mains is to use a step-down transformer for stepping down the 230V mains voltage and adding a couple of diodes as a bridge rectifier. But due to the huge space size and other drawbacks, it cannot be used for all purposes. Another most popular and professional

Tone control or Active equalizer circuit especially bass, treble, and MID control based Equalizer is an important circuit in audio amplifier design. Generally, three-stage active Equalizer filters require three control bass, treble, and MID. The bass control allows the low frequency to pass but blocks high frequency and the treble control allows the high frequency to pass
This Electromagnetic levitation device is a cool to build an anti-gravity project that is exciting and interesting to watch. The device can make something float without any visible support, it is like an object swimming in free space or air. To make this device work, you need to attract an object using the electromagnet, but when it is very
Consider a simple digital watch which is programmed to just show you time, now imagine you want to change its time zone. What would you do? You simply press a button that changes to the menu that enables you to change the time zone. Here, the system can’t predict your external interrupt to its time

Thanks to their high accuracy and fast load recovery time, the R&S®NGM200 power supplies are perfect for challenging applications. Their two-quadrant architecture allows them to function both as a source and a sink to simulate batteries and loads. Their short recovery times enable them to handle fast load changes that occur, for example, when mobile communications devices

UART stands for Universal Asynchronous Receiver/Transmitter and it is a useful hardware feature in any microcontroller unit. A microcontroller needs to receive data, process it, and send it to the other devices. There are different types of communication protocols available in the microcontroller, however, UART is the most used one among the other communication protocols like SPI
