As usual I’ll be using a NodeMCU board (I really did order a lot of them) which uses an ESP8266 ... work! What’s your best and worst idea for microcontrollers that interact with the blockchain?

The build is based around an NodeMCU ESP8266 microcontroller, paired with an L293D motor driver. This lets the microcontroller drive brushed DC motors for differential drive. Power is courtesy of ...

That's where an ESP8266 comes in. It's basically a Wi-Fi microcontroller that you can hook up to more or less anything, and there are a few reasons why you should consider it as the centerpiece of ...

I've been enjoying ESP8266 nodemcu boards for a while. Wondering what folks are doing with the Pi Zeros / if they're effectively the same use case on a different board or what? Click to expand ...
