This PCB is for a simple but powerful webserver used for controlling of home appliances. The hart of the circuit is the ATmega328 microcontroller. This controller was chosen because for it there are available a lot of Arduino libraries. The Ethernet chip used is ENC28J60. A lot of Arduino libraries exist also for it. The webserver is designed in the way that it control 4 channels (3 LED's and a relay). It have two outputs for "status"/"mode" LED's (which of course can be used also for control of other devices). I have used one analog input for some sensor (can be LDR, thermoresistor, thermometer chip, hall sensor, current monitor chip like ACS712...etc).The webserver has two buttons - first for reset, and the second for mode selection or some additional settings. A power indicator LED shows if the webserver is supplied or not.

The movie above demonstrates the webserver functioning using a simple basic program:
