Precision Null Detector

Precise determination of null point in AC/DC bridges helps us to evaluate accurate values of circuit components like L and C. Here’s a null detector that has the following merits: • Same...

Smart Irrigation System

This project is based on the AEIOU heuristic framework of Design Engineering Approach. Design for Performance, Safety and Reliability is ensured in terms of segregation of the low voltage and the high...

Configurable DC-to-DC Converter Module Using Three ICs

Most kits with embedded microcontrollers (MCUs) operate off a single power supply (VCC) source like 5V or 3.3V. But for some experiments you need one or more positive voltages higher than...

Make Your Own Password Locker

A password locker usually has an electromagnetic lock that opens only when the correct password is entered. The circuit presented here for such a locker is a simple, low-cost, hi-security six-digit...

Low-Cost Smart Agriculture System

This IoT-based project monitors soil moisture, temperature, and humidity levels near plants and light intensity near the control station. It turns on water solenoid valve when moisture level goes below the...

A Simple Timer Based On Arduino Uno

Presented here is a simple timer kit built around an Arduino Uno board. It can be used to measure the time delay duration of devices like timer relays, circuit breakers, and...

Simulate MOSFET-Based Ideal Diode

A simple explanation for the working of an ideal diode circuit based on P-channel MOSFET and PNP transistor is presented here. The typical voltage required to turn on a diode is...
3 phase induction motor starter: star and delta connections

Automatic 3-Phase Induction Motor Starter

3 phase induction motor starter often uses star-to-delta converters. The stator coils of the motor are connected in star configuration at the time of power-on and switched to delta configuration when...
