“Made a Flower Pot by combining PCBs together, the whole setup is powered by an Atmega328PU, and it’s basically a Decorative lamp.
I made this flowerpot by combining three different PCBs, I used a diamond-shaped board as a flower petal by soldering them together in star-shaped form.
I used a previously made PCB as a leaf because its shape was somewhat similar to an actual leaf.
As for the stem, I prepared a PCB that holds the flower and leaf together, this stem is then soldered on a base that holds the whole structure and also contains the control board.
I’ve added LEDs on Petals and Leaf, these LEDs connected are in parallel. LEDs on each PCB are connected in parallel, they are all driven by six MOSFETs that are on the Base PCB.
These Mosfets are controlled by an Atmega328PU, we can turn them ON-OFF in sequence or dim them down or do some fading effects on them.
As for the Power, I’ve added a Boost IC Setup on the base that boosts 3.7V from the Lithium Cell into 5V for powering the LEDs and Microcontroller.
This article is gonna be about the build Process of the whole Flower so let’s get started.
