4X4X4 LED CUBE
Bill of materials:
2W solar panel, charge controller, barrel adapter (all distributed by Jeff in class), lithium ion polymer battery - 3.7v 150mAh, 4x4x4 LED cube powered by Arduino nano 33 iot.
Charging the solar panel in the light box
Connection before the LED cube is connected — since we don’t have an extra JST connecter, we soldered headers to the charger and used GND and OUT to connect to power and ground
Cube fully functional ft. Dre :-)
