Over the past years Python became available on more and more platforms, both software and hardware ones. From MacOS and Linux to Windows. From Desktop Computers and SoC Platforms such as the Raspberry Pis to Data Centers. And even on the smallest side Python is available today.

MicroPython implements our beloved language for direct use on embedded platforms built on top of popular microcontrollers, such as the original PyBoard using an STM32 microcontroller, the ESP32 platform and the Raspberry Pi Picos.

In this talk we'll have a look at how MicroPython feels compared to the fully fledged Python implementations, by "porting" a simple application that initially was built to run on a Raspberry Pi to an ESP32 based Microcontroller.

The application was used to retrieve Power Meter Readings via its internal Infrared LED using a small photo transistor based circuit connected to the Raspberry Pi and calculate current power draw from these readings to send them somewhere else for further processing.

We'll see what it takes to make such an application work on a Microcontroller running just on batteries.
