Yo folks
Ive compiled the animated staircase usermod and flashed the binary.
I have manual control over the LED working perfect but struggling to implement the sensors.
Currently i am just shorting pins to replicate the sensors.
Board: ESP8266 nodemcuv3
GPIO Pins:
Top Trigger: gpio 5 (D1)
Top Echo : -1 (does this mean gnd?)
Bottom Trigger: gpio 4 (D2)
Bottom Echo: -1
Any help would be great!
Top Echo : -1 means you this PIN is currently undefined.
use any available GPIO of your board (and specify it instead of -1)
Note: Shorting Pin to emulate a sensor is a Bad Idea.
I actually tried setting other pins also but no joy!
I assumed shorting a pin would be okay as its no different to it working like a button/relay? just closing a contact?
Thanks for the reply!
As usual “It Depends” on what you’re shorting to.
But if you’re “shorting” exactly as you would wire a switch in place of the short there should be no physical damage. You might get a whack more switch bounce than the software expects though.
I haven’t dug through that usermod to see whether Top Echo and Bottom Echo are intended as inputs or outputs. You might want to have a look around for comments on that either in the code or around the forum…
What sensors are you planning to use?
If it’s HC-SR04 ultrasonic sensor then you have written on the board all 4 pins required (V+, trigger, echo, GND)
