Using a Reed Switch as a Current Monitor Circuit

Last updated on 31 May 2026 by Admin-Lavi Leave a Comment

Reed switch is small switch which works with magnet and when wire is near it has current and it makes magnetic field. This magnetic field turns the reed switch ON or OFF, depending on its design and it also helps us show whether current is present or not. Circuit Working: Parts List: Components Values Quantity […]

Adjustable Power Supply Circuit using IC TDA2030

Last updated on 31 May 2026 by Admin-Lavi Leave a Comment

This Adjustable Power Supply Circuit using IC TDA2030 can change the voltage it uses small trick which is little bit surprising; because the chip TDA2030 is normally for making speaker sound loud and can also work like voltage controller. With smart circuit design it gives steady DC voltage and we can change output which is […]
