These days I bought one board of esp32 to learn how to program with micropython.
Esp32 = mcu + wifi + bluetooth .
This package suply us so much components to use :DS1302 timer, ADC , LED ,OLED,RGB,Louder , Relay , SG90 steering engine,IR remote control, DC motor , and all kinds of sensor . It help me to learn how to communicate with these hardware by micropython .

All kinds of sensors
Program
There are a lot of function in Micropython library and other third python library we can use to control all kinds of electronic devices.
Meanwhile , there are some special function for unique chips such as esp32 ,esp8266 .
I take one example here to show how to turn on or off the led light here .
main.py
from machine import Pin
import time
if __name__ == '__main__':
led1 = Pin(15, Pin.OUT)
while True:
led1.on()
time.sleep(1)
led1.off()
time.sleep(1)
You can burn this python file into esp32 board by Thonny or PyCharm .Make sure connect gpio15 with one LED light. Then Restart the board , you could see the led light shine per second .
I will introduce how to program with micropython one by one , and write blog at Embedded/esp32
Thanks for reading my blog .
