MH-ET LIVE MiniKit for ESP32 and Micropython

by shedboy71

This is very similar to the first example, this time I wanted to check out the MH-ET LIVE MiniKit for ESP32 rather than the Lolin32


Parts List

And here is the image from the same site



The code is similar – just uses a different I/O from the Lolin32 – I added debug as I was having problems with an I2CScanner, not really required in this example

[codesyntax lang=”python”]

from machine import Pin
from time import sleep

led = Pin(2, Pin.OUT)

while True:
  print("LED OFF")
  print("LED ON")
