LED HEART PWM FADING :-

                       

                                              The concept for this small circuit  is to create a small heart shape with red LEDs and then to draw a heart shape underneath it on the PCB as a backdrop. Then a microcontroller was added to control the LEDs for both fade and pattern control. Controlling LEDs via PWM allows us to save precious battery life and control the exact brightness of each specific LED.
