This is a tutorial on how to make a dice that has numbers which light up. Hence light up dice.
Step 1: Materials
21 LEDs of any color
Box of paper clips
9 Volt battery
Step 2: Dice
Step 3: 6
For the 6 LED side make that the holes are equidistant otherwise it will not be aesthetic. Set up the LEDs so that one set is negative and one set is positive. The paperclips will help connect the sides together. Make sure that positive connects to positive. The 6th side will be a parallel circuit. Then solder them together.
when going about soldering wires and such it should look the picture above (with iron)
Step 4: 5
The 5th side is the hardest side. Connect the LED's like the 6th side, meaning that one side is positive and one side is negative. Bend the paperclips inward in order to connect the middle LED. Then using the other paperclip solder the other side. You might want to use a resistor for the middle LED otherwise it will burst.
Step 5: 4
This is the lid of the LED. This is a simple parallel circuit.
Step 6: 3
The 3 side is a diagonal setup that will be connected in series. Make sure to connect positive to negative.
Step 7: 2 & 1
This side will need a paper clip to connect to connect the 2-side LEDS. Then connect the one side LED by connecting it to the 2-side by using a paperclip.
