Testing MicroPython with LEDs
MicroPython is now installed on our ESP32 module, but before we start to set up Wi-Fi and build a more complex application, it's always a good idea to start with something simple and then build up the complexity. In the software world, we often print Hello World as a sanity check, but in the hardware world, blinking an LED is a great test.
For a quick test, connect an LED with a 220-ohm series resistor to pin 2 of the ESP32 Devkit-C connect. I connect the resistor to the 3.3 volts pin and the LED anode and then the LED cathode directly to pin 2. When I say pin 2 in this case, I mean the pin that is labeled with the number 2 on the board solder mask. This doesn't represent the physical pin 2 but the I/O pin 2. ...
