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.
Purpose & Overview Of This Project
The goal of this project is to create a PCB with some LEDs connected to a microcontroller. The LEDs should be individually controlled by the microcontroller so much so that each LED can be set to a different brightness level individually. With this control in place 6 modes of operation should be programmed:
- LEDs 'around the heart'
- A total heart fade-in-out
- A wave-like fade bottom to top
- A wave-like fade right to left
- A single row fade in and out
- A single column fade in and out.
