Engineering Projects For You

Free electronics projects, circuit diagrams and software codes available for students and hobbyists. Complete instructions on DIY electronic devices also available. These projects have been tested by EFY and are available with source codes. These are helpful with understanding concepts of electronics including basic components. The projects are designed to be helpful for engineering students and professionals building their own designs and circuits. The projects are also compiled from time to time to provide a single destination for project junkies. Let us know how you feel about the content and any thing you would like us to cover in the future. We hope you enjoy the content on this page!

Microcontroller-Based Morse Code Encoder

Morse code is a method of transmitting textual information as a series of on-off tones, lights or clicks that can be directly understood by a trained listener without using any special...

IoT-Based Smart Agriculture System

Most of us have a small garden, farmland or a plantation area. Our busy schedule, however, doesn’t allow us to maintain it well. But with the use of technology, we can...

Make This Solid-State Relay Driver for Microcontroller

Here is a simple solid-state relay (SSR) driver circuit using a transistor. An SSR is similar in operation to a traditional electromagnetic relay with movable/physical contacts. It employs an optical semiconductor,...

RFID And Face Recognition-Based Smart Attendance System

  Every organisation needs an attendance system to obtain data about its working hours and also keep track of its employee’s punch in and out times. With the state-of-the-art technology, this is...

Develop a Smart Android App for Temperature Alert System

This project presents an Android app to generate an alert (alarm) on a smartphone when temperature of the process under consideration exceeds user-defined maximum temperature. Alarm and annunciator instrumentation systems are widely...

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...

Build A Model Of Satellite Dish Antenna Angle Controller

Presented here is an Arduino-based dish antenna controller to align the position of a satellite dish antenna by setting azimuth and elevation angles. The dish antenna should always point to a...

Gesture Controlled Wheelchair Using ATmega32

Wheelchairs are useful for people for whom walking is difficult or impossible due to some illness, injury or disability. There are different types of wheelchairs. Manual wheelchairs are pushed using their...

IR Remote-Controlled RGB Bulb

Infrared (IR) remote-controlled RGB bulbs available in the market are extremely expensive. Here is a simple, easy-to-build and inexpensive circuit built using Arduino Uno R3. The project demonstrates how to turn...

Mini Fridge With Peltier Modules

It was in the middle of 1821 when J.T. Seebeck discovered that if two dissimilar metals connected at two different points are held at different temperatures, a microvoltage develops. This phenomenon...
