Wes gave me an IoT enabled traffic light! It came with a few wires disconnected and a Netduino as the brains. There is some kind of wireless module attached to pins 0 and 1 (serial port?) so I'm guessing its similar to an HC-06 or similar? It also has 4 relay board, that takes 5 volts DC, and are are active low to turn on each of the lights (the 4th relay isn't hooked up to anything). Driving the pins low I was able to confirm that all three lights are in working condition! I hooked up an 8 channel logic analyzer and probed the various ports, but I didn't see any logic signals that would indicate that it was already programmed to blink the lights. There is nice breakout behind the yellow light, so I might use that to tap in a power supply regulator, so that there is only one outlet needed instead of two?
I'm installing Visual Studio 2015 community edition now, and hopefully with have a development environment setup over the next few mornings.
