Arduino DC Motor Controller Circuit using MOSFET

Last updated on 4 July 2026 by Admin-Lavi Leave a Comment

This project is about controlling DC motor with Arduino and MOSFET, as MOSFET is small electronic part but very strong which can handle big current. Arduino cannot drive big motor directly, so MOSFET help Arduino to run motor safely; therefore, this Arduino DC Motor Controller Circuit using MOSFET is simple, safe and cheap. Arduino Code: […]

Soft ON Circuit for 12V Halogen Lamp

Last updated on 4 July 2026 by Admin-Lavi Leave a Comment

In this post halogen lamp draws very high current at switch ON, then cold filament resistance is very low and this causes sudden inrush current. Lamp life becomes short, then this circuit protects lamp and it also protects outside fuse and switch indirectly; therefore, Soft ON Circuit for 12V Halogen Lamp reduces this problem. Lamp […]
