Engineering Projects For You

Free engineering project ideas, circuit diagrams and software codes for students and hobbyists. Complete instructions on DIY electronic devices. EFY tested circuits with source codes.

Water-level Controller

In most houses, water is first stored in an underground tank (UGT) and from there it is pumped up to the overhead tank (OHT) located on the roof. People generally switch...

3W/6W audio amplifier using TDA2003

This is a simple audio-frequency (AF) amplifier using the popular audio amplifier IC TDA2003. The IC comes in a 5-pin TO-220B package. Circuit and working Fig. 1 shows the circuit diagram of the...

Speed Control of DC Motor Using Pulse-Width Modulation

Pulse-width modulation (PWM) or duty-cycle variation methods are commonly used in speed control of DC motors. The duty cycle is defined as the percentage of digital ‘high’ to digital ‘low’ plus...

Duck Hunt Game Using Arduino And Python

This is a shooting game based on pygame, using Arduino and an accelerometer sensor. In this project a gun pointer is made on the screen, which is moved along x and...

Sunset Lamp

LDR-based automatic lights flicker due to the change in light intensity at dawn and dusk. So compact fluorescent lamps (CFLs) are unsuitable in such circuits as flickering may damage the electronic...

Automatic School Bell

Consider that a school has a total of eight periods with a lunch break after the fourth period. Each period is 45 minutes long, while the duration of the lunch break...

Water Level Controller-Cum-Motor Protector

Many a time we forget to switch off the motor pushing water into the overhead tank (OHT) in our households. As a result, water keeps overflowing until we notice the overflow...

Smart Emergency Light

An emergency light can come in handy at all sorts of time, especially when there's a power outage. Now you need not fear dark nights when power breaks down. Here’s a...

Long Range FM Transmitter

Several circuits for constructing FM transmitter have been published in EFY. The power output of most of these circuits were very low because no power amplifier stages were incorporated. The transmitter circuit...

PC Based Timer

Timers are very useful both for industrial applications and household appliances. Here is a PC based timer that can be used for controlling the appliances for up to 18 hours. For...
