Controlling and Sequencing EL
Working with a just a few EL products is fairly straight forward. However, if you are looking for more of a challenge, fear not. EL projects can become very complex, very quickly. You may have noticed that the effects are somewhat limited on the inverter, and both products hooked up behave the same when plugged into it.
Let’s say you want one color to blink while the other stays solid. You could purchase another inverter battery pack, or you could get one of the many boards out there that are specifically designed to work with EL products. SparkFun carries two such boards, the EL Sequencer and the EL Escudo Dos. Both of these boards are designed to handle many EL products hooked up to them at once, and there are many different effects you can create with both.
For more information, check out the hookup guide on those products.
