More Arduino stuff

Me, Bernd and John M. playing with direct port manipulation on Arduino. Reference here. One thing this allows you to do is write to multiple pins at once.

Gained understanding of the following operators in C:

• | bitwise-or operator
• & bitwise-and operator
• >> right-shift operator
• << left shift operator

Also looked at the SREG register in AVR that stores carry, negative and overflow flags (advanced usage).

Make a dumb Coffee Machine smart with a ESP32

Created a project on github. Details here

The interesting things about project:

• use of ESP32 microcontroller
• Micropython programming
• playing with solid state relays

LPG Detector using Arduino Nano

Secretary John S. pointed out this project.
