Basic code for the node to test input output functionality works. Two LEDs had to change pins as they were input only. PWM on ESP32 for LEDs is different than with the Arduino boards, that was interesting to learn about. Temperature sensor works, and analog input is 12 bit, so from 0 to 4095. Schematic is started. Next step is to complete the schematic, then board layout, and get the proper board outline with mounting holes into the design.
