This is a multifunction bench test instrument built using an Atmega128 microcontroller and incorporate a lot of functions like voltmeter, ammeter, logic analyzer, frequency generator, frequency counter and also provides regulated DC power supply. This device is interfaced with a Windows PC to display the measurements. The PC software is developed in VB 6. The function […]

This is a digital clock project based on an ATtiny26 microcontroller, displaying time on four seven segment LEDs. The seven segment LEDs glow bright white and are multiplexed through PORTB pins, whereas the segments are driven by PORTA pins. The time is normally shown in hh.mm format but it can be switched to display mm.ss […]

There are plenty of wireless devices available on the market that broadcast in the 2.4 GHz ISM band. Such devices include Bluetooth, WiFi, Zigbee, wireless USB, cordless phones, wireless mice and keyboards, etc. This project describes a wireless spectrum analyzer to examine the surrounding radio frequencies in 2.4 GHz band. The project is based on […]

If you are a computer technician and want to avoid the need of a PC on your desk to generate test rasters, this is something you need to build. This is an embedded monitor tester that you can use to test if a VGA monitor is working or not. You don’t need a bulky computer […]

This project describes how to make a digital oscilloscope using an Atmega32 microcontroller and a graphics LCD. The GLCD used has 64*128 pixel dots (GDM12864A with KS0108 processor) and the AVR runs at 16 MHz using an external crystal oscillator. To enhance the speed further, it uses an external A/D converter chip, ADC0820. The sampling […]

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 […]

This project describes an open source color game development platform based on an AVR microcontroller. You can code a color, high resolution, smooth video game, like Super Mario Bros or Commander Keen on this system. All video processing is done by software in background using interrupts, with no external active components. You only need to […]

SAN MATEO, CA (PRWEB) September 18, 2004 Avanquest USA, a leading developer and publisher of small office/home office (SOHO) software, announced today that it has published In A Flash TM animation software, developed by NETGUI. In A Flash lets business owners create professional-looking animated content without the need of expensive and complicated programs. With a […]

Have you ever seen a business card with a computer chip embedded on it? This one does. It has an ATtiny85 microcontroller chip that stores all your personal details. You plug it into an USB port of your computer, and find the details about the person opened into a text editor. The firmware uses V-USB […]

This is an experimental board for ATTiny2313 microcontroller that provides a 10-pin connector for in-circuit serial programming, and other header pins to access I/O pins. The AT2313 microcontroller runs on an external 10Mhz crystal. The board has a push button reset switch for resetting the microcontroller. The onboard regulator provides a +5V DC to the […]
