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.

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 [...]

This tutorial shows you how to decode SONY Remote Control using microcontroller AVR. The project use external interrupt at the falling edge to detect the pulse. The project use AT MEGA 16 and vcd remote control sensor or you can use any type sensor that have filter of 38 KHz to 40 KHz on [...]

If you tired with All TVs everywhere or you want a break from advertisements? TV-B-Gone is what you need. TV-B-Gone is a universal TV remote control which only has one button to switch a TV on or off. As you can see the device is so small that it easily fits in your pocket, so [...]

Air-Byte IR Transceiver is a PIC based tranceiver that transmit & receive infrared signals with your PC serial port. The project provides a simple method for receiving serial data on one pin, and outputting serial data on another modulated at the IR detectors band-pass frequency.
The brain of the Air-Byte transceiver is a tiny 8-pin PIC12F508 [...]

R/C Pulse Generator uses Microcontroller AVR AT90s2313 to measure resistance values and generate R/C style pulses that will be fit for driving servos or testing R/C controlled robots without the transmitter. It measures four channels and provides four R/C style pulses. Indication of the current pulse width and when the board is in CALIBRATE mode [...]

The TriWheeler is a radio-controlled robot with three wheels. The lack of the fourth wheel is far from the only thing that renders it distinctively different from typical radio-controlled units. In addition to the capability of being freely controlled with a remote control, The TriWheeler has a smart autonomous mode that allows the unit to [...]
