The word clock is a unique time-telling device and uses a grid of letters to spell the time. the material we use is an Arduino and an RTC, Shift registers 74hc595, ULN2803a Darlington Transistor Arrays axis LED drivers, white LED strip of 2m, 16 pin IC socket x3, 18 pin IC socket x3, 12v power source may be battery or wall adapter, Protoboard, Connecting wires, Male header pins, Jumper wires- female-female and as the frame and to make the grid we use the 3D printer.
