This is LED lamp project powered by solar. It will harvesting the Sun during the day and charging the battery. The project uses SEPIC converter that capable of boosting or dropping the input voltage. It allows the use of a battery with a voltage close to the LED conduction voltage. The project is built [...]

The Image Capture Board (ICB) is designed to capture images at a resolution greater than 3600dpi with 8-bit grayscale depth. This board was created as the central component of a system capable of detecting counterfeit currency. Scanning at such a high resolution would allow for easy detection of micro printed characters as well as [...]

If you need electronic simulator with the ability to set the speed of the rotation, and start and stop on demand as in the actual system then check out this Encoder Simulator. The project very useful for troubleshooting or developing new programs for control systems when there is unavailability of the target system for [...]

This project is the implementation of Ethernet Bootloader for ATmega128 MCU. It shows the simple way to add Ethernet communication and Ethernet firmware update features to AVR MCU. This project will help field engineers to do firmware-updating remotely on consumer network-based systems like security systems, industrial control or monitoring systems etc.

This four channel pulse width modulation (PWM) controller is built around Atmel ATMega16L. It has RS232 serial interface for computer control, four 10 bit analog inputs and a 12-button keypad interface. The controller also has four indicator outputs (which may be configured as general purpose outputs), an alphanumeric LCD interface (with backlight control), three general [...]

This AVR-based embedded system of high-resolution ultrasonic radar will help the driver to avoid potential accidents by telling the driver the minimal distance of obstacles behind the car which may be neglected by drivers. The system uses TV On-screen character display (OSD) technology as main display and LED as secondary display. In the light-emitting bars [...]

The AVR Ethernet I/O board with accompanying PC control software offers remote control of 4 relay activated devices and status monitoring of 4 opto-coupled inputs over the Internet. Remote control is accomplished using any web browser-abled computer, or by running the custom “Ethernet I/O Control Panel” Windows software on an Internet ready PC. Browser based [...]
