Perhaps. It will have to come a bit later as I already have a full schedule for what I will be posting here. But I think a project like this is quite doable. :)
Hey @evyxxx, the most straight forward approach is wiring up each LED with a single output pin. Therefore 25 ouput pins are needed. I recommend using an Arduino Mega 2560 or clone. This board has enough GPIOs to get you started. Use a Breadboard to directly wire up your LEDs. Do not forget the LED series resistor for each LED to limit the current. There are LEDs with integrated series resistor.
I guess so... What do I need to make it? Interested in building this project on #steemit? Later I will show the base of the lamp I want to make :)

Warning: Usually signal outputs should not be used to provide current, but your use case will not exceed the current limitations (https://playground.arduino.cc/Main/ArduinoPinCurrentLimitations Atmel ATmega2560/1280/640 (MEGA) Current Specifications)
