Arduino Power Led Driver

This board should be used to interface LED strips and LED spots for my kitchen

This board is developped for an Arduino Mega Board. Thanks to BD139 transistors we can drive 8 LED Strips, 6 white spots, a beeper and 2 diagnostic LEDs. There is also an onboard thermometer LM35(Temp). This board is power by using a 100W/12V power supply. There is a voltage regulator (7805) to power the Arduino Board.
