To get better UV expose, Andrianakis has built new Switch Timer that will turn of his UV exposure box after some time. The timer uses ATmega8 as main processor and two 7-segments LED as display. There are two buttons for set and start the timer. When time runs out, microcontroller switches relay and also sounds a buzzer. The time …
My microcontroller-powered prime number generator/calculator is virtually complete! Although I’m planning on improving the software (better menus, the addition of sound, and implementation of a more efficient algorithm) and hardware (a better enclosure would be nice, battery/DC wall power, and a few LEDs on the bottom row are incorrectly wired), this device is currently functional …

These Android figures are cute, but they don’t actually do anything. Let’s change that. Have a look at the video: These are the steps to make an Android that reacts to sound, moves it’s head, sends out Morse Code messages and displays some cool light patterns. In the video the LEDs in the body are …

The Turnigy 9x is a cheap Chinese radio transmitter widely sold by hobby king and other retailers under a variety of names. This is a computerized radio transmitter and is already a great deal for the price ($53 currently) and pretty capable if you can figure out how to use the stock firmware. The microcontroller running the show is …

When you think about building a radio transmitter circuit, the first thing that comes in mind is it requires too many analog components. But wait a minute, this guy demonstrates an AM transmission using a microcontroller. The interesting part is it uses a plant as an antenna for transmission. This project is based on Atmega324 …

The parts to the right of the green capacitor are the FM radio transmitter. The parts between the 8 pin DIP and the transmitter are the resistor matrix. One capacitor, C5, is mounted on the back of the board, and one other capacitor, C11, had not yet been installed. It was later installed just below …

An LMX1601 Phase locked loop, a discreet FET VCO, and an AVR micro controller combine to make a stable, easy to use monophonic FM transmitter that includes a an audio activated switch that turns the transmitter on only when its being used. Notice: Before operating a radio transmitter, find out what kind of transmitter operation, …

Aim of this project is to present a way to store a large quantity of data into microSD card in files with FAT32 format. Here, ATmega32 is used for data collection and microSD interface. The data is received from in-build 8-channel ADC of ATmega32. One channel is used for reading temperature from LM35 sensor and remaining channels …
Here is my project on interfacing of SD Card (microSD). microSD cards are available very cheap nowadays, a great option for having a huge memory in any embedded system project. It is compatible with SPI bus, so the interfacing is easy. SD card adapters are also easily available in market, one can easily make a bread-board adapter by soldering …
