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.
Welcome to Episodes #01 of the new Obviate.io video series where we’ll be flashing Micropython 1.9.3 onto a Wemos D1 Mini ( ESP8266 ) development board using Apple macOS.
Recently, I’ve discovered that which is known as Arduino. Basically, it is an open source, open hardware microcontroller. They give you the software and the hardware plans online and you can build your own. Of course, you can always buy a premade kit (which is my preference). So… what does this “microcontroller” do? Basically it controls simple input and output on a low level. You want to make something turn...
