Mushroom arduino led lamp

Introduction

Honestly i made this because i was quite bored and also i wanted something cool for my bedroom but when i finished it my father convienced me to leave it in living room because he liked it, so thats what happened and when my grandparents came for visit they all really liked it even though they arent into crazy weird-core lsdeeee magic lamps.

What does it do 

This beautiful creation has basically three modes.

1. Changing colors using two potentiometer ( two values into "square"  data rgb + yellow)
2. Random color transition, led intensity is changeble by one potentiometer and  transion time is controlled by the second
3. Random color showing up, potentiometers work the same like in the last mode

Hardware

The components should be easily obtainable, i used the most common ones. I do not recommend buying them on temu btw because you may end up wirh burned house but i dont care really honestly.

2 x potentiometer	for example PK1023d
switch on/off	slide switch button (the size must be 4x9mm)
mode switch	push button(12,2x12,2mm) with square top/ touch sensor
arduino	arduino nano/uno (board that has at least 3 pwm pins), but better are smaller boards because they fit easily
5 x leds	rgb leds with common cathode
adapter	you may use any dip break-out adapter that will split dc to vcc and gnd (o r more)

Some of the parts are powered by digital pins instead of regular gnd or 5v its safe but it will shorten the lifespan of arduino.

Printing

For mushrooms i used some cheap white pla. For stems i recommend using brim.

Base and potentiometer caps were printed with prusament woodfill. Caps need support.

 Print the Topbase_oval/rectangular_parts.stl and Bottombase_oval/rectangular.stl (if you just wanna use different base than the original just print noparts version instead ). Print touch_sensor_holder.stl if you are using sensor, if you are using button print button_cap.stl

Final initicialization ( with arduino)

1. Wire leds on very long wires (at least 20cm, for American people™  its probably 1,2 of ben and jerries ice cream box or two glazed donuts) using small bread board or tinned breadboard and then cut it to make it fit into box. Basically connect all r pins, g pins, b pins and cathode pins together.  Without wires it should look like this: 

      2. Solder wires to button,switch,potentiometers or use breadboard. 

 

      3. Connect to arduino and upload it, digital gnds and vccs use for potentiometers or button(leds are to consuming). This is how the switch with adapter circuit will look like(- is gnd, + is vcc adapter). Orange wire is vin pin.

      

4. try to make it fit and honestly good luck.
