Useful information.
ESP32 DEVKIT
Espressif's ESP32 - got this board to play around with...
--------------
ESP32-DEVKITV1
--------------
- clone of DOIT's ESP32 DEVKIT V1?
- ESP-WROOM-32 (ESP32-D0WDQ6)
= ESP32-D0WD-based modules with integrated flash
- DECISION20200822:
= toolchain and build environment is simply not worth it!
= WILL USE micropython instead!
= **added-A-LOT-later** OR, use Arduino IDE?
-----------
micropython
-----------
- get some tools

Temperature Sensor
One of the most commonly used sensor is the temperature sensor. There are quite a number of sensors to choose from and it all depends on your requirement.
