I use 1 RPI3 and two KY modules. One is connected to eg GPIO10, 3V and GND and the other module is connected to eg GPIO 12, 3V and GND
HI,
I set everything up according to the first post, but receives an error message
"Error: EventSystem: in Gas: [string "commandArray = {} ..."]:19: attempt to perform arithmetic on a nil value "
could anyone help me solve the problem?
