led-and-key-1.yml

##
## My latest version targets the ESP32. See the code at
## https://gist.github.com/kdorff/396a11b5bb29142f09c1f52242c546e5
##
## ESPHome configuration for led-and-key1
## * LED0 is lit if the back door autolock is enabled
## * LED1 is lit if the front door autolock is enabled
## * ..
## * BUTTON0 toggles the back door autolock enable
## * BUTTON1 toggles the front door autolock enable
## * ...
## * BUTTON6 will decrease the intensity
## * BUTTON7 will decrease the intensity
##
## The global ledkey1_display controls what is being displayed.
## if (ledkey1_display == "") the current time and temperature
## will be displayed, instead (obtained from HA).
##
## Wiring of the TM1638
##    3.3v and GND from 3.3V and GND from the microcontroller (may not be ideal?)
##    DIO on D7, GPIO13
##    CLK on D6, GPIO12
##    STB on D5, GPIO14
