Lately, I have been doing some experiments with programmable controllers. One of my projects has been with controllable switches and Arduino. In fact, my programming club had a problem, where this month’s speaker backed-out. With six days to go, the club president asked if anyone would like to present. I stepped up.
I thought it would be good to show a nice diagram of my project. I noticed that most people use a program called Fritzing, to do the diagrams. This program is great, but it does not have all of the parts that are commonly used with Arduino.
The program allows you to design your own parts. However, the part designer is very fussy. After a bunch of searching and trying, I managed to design a part that looks very similar to my SunFounder 2 Channel 5V Relay Shield Module.
I thought it might help a few people if I shared it. I’m pretty sure that it is not perfect (not-even close), but it is better than nothing. If you are using another 2 channel relay shield module, this is pretty close.
You can download it from my other web server: Fritzing part for SunFounder 2 Channel 5V Relay Shield Module
If you would like to make improvements to it, I would be glad to update my Fritzing part. If anyone is interested, I could probably make this into a 4-channel or 8-channel, without too much effort. Just ask (below).
