The following post discusses the wiring connections for driving a DC motor in clockwise and anticlockwise directions with the help of a single toggle switch and a relay circuit. The idea was requested by one the interested followers of this blog. I have explained more: Technical Specifications We have our project in school. Our professor […]

High Voltage DC Motor Speed Regulator Circuit
In the realm of motor control systems, high voltage DC motors play a crucial role in numerous industrial and automotive applications. Efficiently controlling the speed of these motors while ensuring operator safety and isolating sensitive components can be a challenging task. However, with the advent of advanced technologies, such as optocoupler motor controller power stages, […]
XL6009 DC-DC Converter IC: Pinout, Working, Circuit Diagram, and Applications
XL6009 is a DC-DC switching regulator IC, and we use it where lower voltage DC has to be lifted higher, or sometimes changed other ways, boost, buck-boost, flyback, even inverting, all that is possible depending how outside parts are connected. Why XL6009 is More Efficient Than Linear Regulators It is not like old regulator types […]
220V AC to 12V DC Flyback SMPS Circuit using IC 555 (7555)
This practical flyback SMPS circuit uses ICM7555 as the main oscillator, and yep the whole idea is to take 220V AC mains directly then convert it into isolated low voltage DC through a ferrite transformer.. Unlike many PWM controller designs, here we have very few parts but still it gives mains isolation, voltage feedback, current […]
Arduino based DC Voltmeter Circuit – Construction Details and Testing
In this post, I will show how to construct a DC voltmeter using Arduino where the readings are displayed in 16×2 LCD. The proposed voltmeter design can read up to 30V with tolerance of +/- 0.5 volt. We are going to see how this setup functions and explore other possibilities we can accomplish other than […]
3 Watt, 5 Watt LED DC to DC Constant Current Driver Circuit
The following article provides a simple yet very decent solution for driving powerful LEDs rated at 3 watt or 5 watt. Circuit Objective These 3 watt 5 watt and similar high watt LEDs are able to produce highly intense and powerful light outputs, however these are extremely vulnerable too with their operating parameter. I have […]
