AVR Projects

Compilation of AVR DIY Electronics Projects published on our website…

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 long run, a small-time deviation will be...

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 at RF receiver module in serial format....
Smart Light Circuit

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, irrespective of whether these are being used...

Countdown Timer

Sometimes there is a need to switch on or off electrical appliances or gadgets after a predetermined time. The circuit presented here can switch on/off any electrical appliance (load) through a...

Part 1 of 3: USING AVR MICROCONTROLLERS FOR PROJECTS

The AVR 8535 microcontroller and its new version ATmega8535 are versatile, high-performance but low-cost chips. This article series covers typical applications of this processor illustrating its power and cost-effectiveness in an...
Joystick Controlled Robot Transmitter Circuit

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 as compared to switches. The circuit is simple,...

Part 2 of 3: Using AVR Microcontroller for Projects

In the first part of this article, we had described the main features of the AVR microcontroller and the hardware/software required for an AT-PROG programmer board interfaced to the printer port...

Wireless VU meter

VU meter is a standard device that indicates the signal level in audio equipment. Unlike other devices, this meter doesn't require a physical connection between the audio source and the circuit. Wireless...

Voting Machine Using AVR Microcontroller

Polling by electronic voting machines (EVMs) has become a norm during elections. Unlike paper ballot systems, EVMs are safe and reliable as these rule out the possibility of invalid voting. These...

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 share today is new and unique. So...
