My breadboard is working and I have tested most of the OS features. Today I also added buttons. I used buttons on ESP GPIOs pins(12,14,16 on a NODEMCU 0.9) they need pull-up resistors to properly work but everything works fine.Tried also the ADC buttons on a DFrobot(freetronics) shield but they didn’t work first try but I didn’t put much effort in it. Do you need me to check any future or specific hardware configuration?
