Blynk app menu feature Self Watering Plant Pot

meganhamilton88 · December 5, 2023, 9:55pm

Hi, I am building a self watering plant project which requires the pump to automatically water the plant depending on moisture levels. We are now trying to add the Blynk app into our code which will allow us to view the values on the app. We have successfully got it to view the moisture and light levels as well as temperature.

We are now trying to add a menu feature to the app which should allow us to pick between 2 or 3 different plants (they all will have different moisture levels). We want it so that the user will pick which plant they will be using and then it will run the correct code suitable for each plant. Does anyone know what i would type in my code to successfully get this working? I have attached the code that i have so far below:

#define BLYNK_TEMPLATE_ID "TMPL5fmzE-Hpj"
#define BLYNK_TEMPLATE_NAME "Quickstart Template"
#define BLYNK_AUTH_TOKEN "xn54Yt1kZ8AX_7sozzQBeUZoEmolmOKR"
#define BLYNK_PRINT SerialUSB
#include <SPI.h>
#include <WiFiNINA.h>
#include <BlynkSimpleWiFiNINA.h>
#include <LiquidCrystal.h>

char ssid[] = "iPhone";
char pass[] = "password";

BlynkTimer timer;
BLYNK_WRITE(V0){
  digitalWrite(7, param.asInt());
}

LiquidCrystal LCD(0,1,2,3,4,5);
#define analogPin A2
#define beta 3950
#define resistance 10
int lightRead = 0;
int lightLevel;
int button=6;
int moistureSensor;
int moisturePercentage;
#define moisture A4

//const int buttonPin = 6;// Pushbutton pin;
const int redPin = 8;    // Red LED pin
const int greenPin = 10; // Green LED pin
const int bluePin = 9;   // Blue LED pin

int motorState = LOW;      // Motor state (OFF for default)

const int pump_pin = 11;
