Video Tutorial: Writing code onto Micropython Wemos D1 using Ampy

Last week we covered how to flash Micropython onto an ESP8266 (Wemos D1 Mini) but we had to type our code into the REPL by hand. That’s not terribly useful for a real world project, so this week we learn how to upload code and make it run on boot. We’ll be using a tool called Ampy, by Adafruit, since the Micropython world is a little immature.

Connecting a HID Prox Pro II RFID reader to Arduino

Arduino based RFID reader projects are a dime a dozen. It’s great and wonderful how plentiful and easy they are. Checking out Adafruit or Sparkfun one can find dozens of cheap components that are almost ready to go. The common factor is that they are all 13.56Mhz or Mifare compatible. Nominally this means cheap (And plentiful) components and fobs, but it also means that the systems aren’t compatible with most...
