Design a 12V/27W SMPS Circuit with UC3843 SMPS Controller IC Switching Mode Power Supply, or simply SMPS, is a type of Power Supply Unit (PSU) that uses a switching device (such as a transistor or MOSFET) to convert the source, which can be AC or DC, to a constant DC voltage. Switched-mode power supply circuits (SMPS) are most often required in many electronic designs to convert the AC mains voltage to a suitable level of DC voltage… |

Automatic Irrigation System using an Arduino Uno Every one of us likes a little greenery in our houses, don’t we? Plants require really low maintenance and can be left for days without supervision, but our long trips extending over a week or 2 can be detrimental to the health of plants due to the lack of moisture in the soil. In such situations, the plant may wither or die due to the absence of proper watering. In order to… |
