Turn on an led in a low voltage circuit
It's almost the holiday season and you might want to get geekie. If you are unsure about this, get profession help for the project. Try this at your own risk. We take no responsibilities for anything you may or may not do. This article is not a how to, but it is informational. What we want to do is to control lighting so that we can turn it off or on with electronic equipment instead of doing it manually with a traditional light switch. In this case, we may want to control holiday lights Such as an Xmas tree. We could use the light switch like above, or we can use a computer or a micro-controller. In this case we will suggest three posiblilities. The computer using a traditional parallel port, A raspberry Pi, or an Arduino. The simplest way to do this is with a solid state relay. Basically it is just like turning on an led. If you turn on the data line so it goes to near 5 volts, the led will turn on or the SSR will allow the output side to work. An SSR let y...
