In this article I will try to tell you about the gift I made for my girlfriend!
I got here is a LED heart.
I apologize for my bad English! 
The basis of the scheme is a microcontroller Atmega8, 1K resistor, selected in such a way as not to overload the microcontroller ports. SMD resistors and diodes, size 1206.
In order to fill in the microcontroller firmware, you need to solder the wires to the pads on the board. Around the microcontroller pins are derived for spi interface (MOSI MISO SCK RESET). The firmware can be downloaded here.
DIY SMD LED heartTo formalize the a scheme which I soldered, I placed it in a wooden frame, and make the background and glued two small ladybugs. Valentine’s Day is approaching, a gift sure to enjoy your loved ones people!
Download files PCB and firmware for the microcontroller can be here!
