A Circuit to operate an LED on 120V Mains

Posted on

So, if you look at my post about Node-RED experiments, you’ll notice that the “power” LED isn’t lit on my home-made portable breadboard.  I could have just wired the LED to the +5 of the power supply, but if the supply died then all lights would be out, including the “power” LED, which wouldn’t really […]

Experimenting with Node-RED

I’m using Pete Scargill’s super timer node Big Timer on my Intel Edison and a Raspberry Pi W to experiment with Node-Red and developing a Dusk-Dawn timer.   My wife is always mentioning that our low-voltage outside lights along the sidewalk to our front door always need to be adjusted because of Daylight Savings Time […]
