Power Path Controller System using LTC4412 to Switch between Primary and Auxiliary Power There are many situations when our circuit design has two power sources such as an adapter and a battery or it can even be two other power supplies from two different outlets. The requirement of the application can be something like it should always need to remain ON during power failures by using and additional power source that is available. For example, a circuit that is… |

Design your own Compact 5V/3.3V SMPS Circuit for Embedded and IoT Projects 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 way is to use Switch Mode Power Supply Circuits for converting your AC… |

Tips and Techniques for Designing Small Circuit Boards to Shrink PCB Size For any electronic product, be it a complex mobile phone or any other simple low-cost Electronics toy, Printed Circuit Boards (PCB) is an essential component. In a product development cycle, design cost management is a huge issue and PCB is the most neglected and costlier component on the BOM. PCB costs much more than any other component used in a circuit, so reducing the… |

DIY Raspberry Pi RGB LCD HAT Raspberry Pi Hats are the same as shields for Arduino, they can directly fit on the top of Raspberry Pi and don’t require any further connections. Here we are going to build an RGB LCD Hat for Raspberry Pi on PCB. This LCD Hat consists of a 16x2 LCD module, five switches, and three NeoPixel LEDs. Here switches are used to change the text on display and NeoPixel LEDs are used… |

Build your own Adjustable Electronic DC Load using Arduino If you have ever worked with Batteries, SMPS circuits or other Power supply circuits, then often it would have occurred that you have to test your power source by loading it to check how it performs under different loading conditions. A device that is commonly used to perform this type of test is called a Constant Current DC Load, which allows us to adjust the output current… |

Fastest Arduino RC Car using Coreless DC Motors and nRF24L01 RF module RC cars are always fun to play with, I am personally a big fan of these remote-controlled Cars and have played (still do) with them extensively. Most of these cars today provide a huge torque to handle rough terrains, but there is something that was always lagging, its Speed!!.. So, in this project, we will build a totally different type of RC car… |
