How do you make LED signs?

Answer

To make lead signs you will need to draw your final design onto the poster board. Measure the length of each line on your design. Poke a hole every fourth inch along this mark with scissors. Put LED via this hole from the rearmost of the poster board. Use the LED adder in the references section to calculate how you should wire your LED sign board. Solder the LEDs, resistors and 9-volt battery together, Turn on your LED sign board by connecting a battery. Bind the LEDs to the poster board with glue and tape the nine volt battery to the posterior of the sign.
