001 - ESP32 MicroPython: What is MicroPython

MicroPython is essentially a Python created for microcontrollers. MicroPython is a light-weight and compact implementation of Python Programming Language. It is stripped and trimmed down in order to work with embedded devices which basically has limited resources. And with the help of machine modules, we can easily communicate with the hardware input and output devices. […]
