Fading LED Heart Birthday Present
Posted September 27, 2012 by Chris
“The concept for this small birthday present was 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.”
