Night Light Base

thingiverse

This is a night light base that fits custom-made RGB LEDs controlled by an Arduino Mini Pro and a rotary encoder with a push button. The project is indeed overkill, but it's what I had on hand. I used these specific Arduinos and encoders: https://www.amazon.co.uk/gp/product/B007YQZUEE/ref=ox_sc_act_title_1?smid=A1NBUX8FDB1DWX&psc=1 https://www.amazon.co.uk/gp/product/B0085I4D5C/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 However, any Arduino and encoder combination should work. Turning the encoder controls brightness, while pushing it cycles the colors. At present, the color cycle is {off, white, red, green, blue, magenta, cyan, yellow}. The included Arduino code has pinouts detailed within. The LEDs used are fully addressable types, which I obtained by cutting 3 off some leftover ones from another project. These types of LEDs usually come in 2-3m runs and can be purchased here: https://www.adafruit.com/product/1138. For the power supply, I simply cut a regular USB cable and used the red and black wires (5V and GND) to plug it into the Arduino. Any USB brick should work for this amount of LEDs, as they only draw up to 140mA at maximum brightness, but typically around 40mA when set to night light levels. The idea is to place a hollow figure on top like the one pictured here: https://www.thingiverse.com/thing:1912559. I made it for my son, who wanted the option to remove the figure so he could take it to school, etc. At some point, I plan to print/make a knob, but it's been harder for me to rotate it than for my son, so it hasn't been a priority.
