Hi, I found quite hard to add new inputs and outputs to the UserBot as you have to modify a few files of the library so I created a little guide. In this example I added one output led on pin 5 and one input button on pin 6. It's by no means perfect but it will help I hope, don't hesitate to review it and correct it or add some stuff to it:

Change to add new output/inputs

--EEPROM_Utils.cpp,

Add your inputs and outputs types and name ex: " inputs[4].type = BUTTON; strcpy(inputs[4].name, "Button4"); outputs[0].type = LED; strcpy(outputs[0].name, "Led1"); " Find the different types of inputs and outputs in the file "GroBot_Variables.h"

Under "//Clear unused IO's" in : "for(ei=4;ei<10;ei++)" replace ei=4 by the number of inputs that you have in : "for(ei=0;ei<10;ei++)" replace ei=0 by the number of outputs that you have

--SensorsTask.cpp,

Under " //* INPUTS ***// /Here you need to set your used pins as inputs or outputs/ " Add your new pins setting ex: " pinMode(BUTTON_PIN3, INPUT);
pinMode(OUTPUT1_PIN, OUTPUT); "

Under "case GET_IOS:" Add if it's an input something like that: " if (digitalRead(BUTTON_PIN3)) inputs[BUTTON_INDEX3].value = 255; else inputs[BUTTON_INDEX3].value = 0x00; " Or if it's an output: " if (outputs[OUTPUT1_INDEX].value == 0) digitalWrite(OUTPUT1_PIN, LOW);

else digitalWrite(OUTPUT1_PIN, HIGH); "

You can add more "case" for your output and input there

--Grobot_variables.h

Add define more input index and the pin associated ex: "

define BUTTON_INDEX3 3

define BUTTON_PIN3 6

" For the output you have to keep the index unchanged and change the output pin like that: "

define OUTPUT1_PIN 5

You have the possible inputs and outputs names you can use at the end of the file

OpenWeGrow / UserBot

UserBot adding inputs and outputs #2

define BUTTON_INDEX3 3

define BUTTON_PIN3 6

define OUTPUT1_PIN 5
