ESP8266: NodeMCU Pin mappings

I had some problems with this when I first used a NodeMCU board. It’s simple enough to figure out, but it still can give you a momentary urge to yank out hair!

Thanks for making this easy to see and understand!


The objective of this post is to explain how to use the ESP8266 library defined constants that have the correct mapping between NodeMCU and ESP8266 pins.

Project: Camera Lighting – Prototyping

Here, I'm going to step through the prototyping process of getting this to work. Step 1:  The Power I like to set up the power component of my projects first, since if that doesn't work, I'm not going anywhere. Using PCBs with breadboards without soldering isn't all that friendly, but you can make it work… Continue reading Project: Camera Lighting – Prototyping

ioLinker FPGA Update!

This is sort of a reminder post. I wrote a more in-depth article about these iolinker boards earlier, and their Kickstarter campaign is set to end, at the time I'm writing this, in 69 hours. They only need about $700 at this point! This thing is so close to becoming funded, and a reality. I just bumped up my pledge a little bit. It wasn't big before, and it still isn't, but every little bit helps when you're this close.
