I made this as alternative to bet site night light. I'm using a ribbon type LED trip thats stuck to the mack of a head board which hids a bit between the carvings on head board and the control module is basically a PWM controlled with 3 buttons: Up, Down, and On/Of switching and IRL540...
Small development board for using an ATtiny44A or similar 14-pin ATtiny in SMD package on a breadboard.
Minimal hardware design featuring only MCU, breadboard friendly headers with extra power lines, ISP header for serial programming and reset button.
Uses bare chip and limited extra components.
Also usable for ATtiny84, ATtiny441 and ATtiny841.
You can find some more [information about the project on my website https://josef-adamcik.cz](https://josef-adamcik.cz/electronics/led-cube-4x4x4x-attiny84-74138.html)
Gallery with finished build [available on imgur](is available on imgur).
A [source code for attiny84 is at Github](https://github.com/josefadamcik/ledcube_4x4_double74138).
