In a previous post we flashed a W32-WROOM-32 with MicroPython and successfully got to an interactive python prompt via serial. Now we will create a simple python script and upload it to the ESP32 and have it run on boot. First, lets create a really simple python script -: import time print(‘Hello world! I can […]
