Digital Clock

thingiverse

Before you connect anything, connect the Buck converter (LM2596S) to a 12v power supply and set the output voltage to exact 5.0 volts. Print the face.stl file in white at 0.15 layer height. The rest can be printed at 0.2 layer height. Make sure when you put the LED'd on the plate that the directions of the LED is according to the layout. I have used solid wire for connecting the LED's together with the printed plate ( led_plate_x_4) . The clock dim as it darken so that the light does not bother you in the night. Still bright enough to read the clock. 2 Push buttons to set the Hours and minutes. The software for the Uno is "corrie_clock.tex". Open with notepad, copy and past in arduino programmer. Enjoy.
