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...
Microcontroller Projects: AVR Bootloader Circuit for Trouble-free Programming
Normally, ATMEL’s AVR microcontrollers are programmed using programmers. There are many ways to program the AVR microcontrollers, such as in-system programming, parallel programming and...
Make This Joystick-Controlled Robot
The circuit presented here uses a joystick to control a robot. A joystick is more comfortable to use and accurate to control a robot...
Web-Based Water-Level Monitor and Pump Controller
Several articles about water-level controllers for overhead tanks have been published in earlier issues of EFY magazine. But the project we are going to...
Solar Compass with OLED Display
The solar compass presented here is a navigational tool, which helps in finding directions through the position of sun in the sky as reference....
GPS Navigator
Global positioning system (GPS) is a wonderful technology that has made navigation systems highly accurate and efficient in recent years. All the mobile phones...
Build Your Own Miniature VAW Meter
The circuit presented here can measure voltage (V), current (A) and wattage (W) on an OLED. It is actually voltmeter, ammeter and wattmeter circuits...
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...
Make Your Own Smart Light
Most textile retail stores have trial/changing rooms for customers to try on new clothes before buying them. These rooms are illuminated all day long,...
Build A Serial Data Debugger
A Serial Data debugger is a tool used to test and debug other programs or target programs. This project is based on Atmega16A microcontroller...
Appliance Guard To Prevent Damage
This circuit monitors the AC current flowing through an electrical appliance and automatically turns the appliance off when the current goes beyond maximum or...
Make This Simple Graphical LCD Scope
This scope reads input signal and displays the output waveform on a graphical liquid crystal display (GLCD) having 128×64-pixel resolution. The signal is fed...
20 Practical AVR Projects with ATmega Microcontrollers
AVR is a family of microcontrollers developed by Atmel beginning in 1996. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. ATmega series are one of the types of AVR microcontrollers with features like...
Industrial Digital Thermometer
Presented here is a 4-digit Industrial Digital thermometer based on ATmega16 microcontroller (MCU), which can measure temperature up to 1024°C.
Normal thermometers have a limited...
Music-Operated RGB LED
Here, RGB LED light intensity and colour change with the rhythm and volume of music. It is a great idea to have such a...
RF-Based 12-Bit Signal Transmitter And Receiver
The circuit presented here converts 12-bit parallel digital data to serial data and then transmits it through RF transmitter module. Serial data is received...
Simple and Low-Cost GPS Clock
Real-time clock (RTC) integrated circuits (ICs) are used for reasonably accurate time displays. The accuracy of RTCs mostly depends on the crystal. In a...
