fishFeeder

fishFeeder is an Arduino (ESP8266) Telegram controlled fish feeder which I use to feed my fish when I'm away.

Components

• NodeMCU - ESP8266
• Servo Motor

Parameters to change:

To generate your new Bot, you need an Access Token. Talk to BotFather and follow a few simple steps described here.

Replace with your Telegram Token in fishFeeder.ino:

#define BOTtoken "XXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

Replace with your chat_id to prevent other people from feeding your fish

if ( chat_id != "REPLACEME")
      bot.sendMessage(chat_id, "Hey, you are not allowed to play with my fish!", "");

In secrets.h, fill with your WiFi SSID and password:

#define SECRET_SSID ""
#define SECRET_PASS ""

Necessary libraries:

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#include <UniversalTelegramBot.h>
#include <Servo.h>
#include "secrets.h"

You also have to install the ArduinoJson library written by Benoît Blanchon. Search for it on the Arduino Library manager or get it from here.
