Motion Sensor Discord Bot Project

This project is an IoT application that uses NodeMCU and a motion sensor to detect motion and send notifications to the user through a Discord bot. It also allows the user to control the motion sensor through Discord.

Features

• Motion detection using NodeMCU and a HC-SR04 Ultrasonic Distance sensor.
• Sending notifications to a specified Discord channel when motion is detected.
• Controlling the motion sensor through a Discord bot.

Requirements

To use this project, you will need the following components:

• NodeMCU ESP8266.
• HC-SR04 Ultrasonic Distance sensor.
• Breadboard and jumper wires.
• USB cable for programming the NodeMCU.
• Discord bot token (obtained from the Discord Developer Portal).

Connections

To connect the motion sensor to NodeMCU, make the following connections:

• Sensor VCC pin -> NodeMCU 3.3V pin.
• Sensor GND pin -> NodeMCU GND pin.
• Sensor TRIG pin -> NodeMCU D1 (GPIO 5) pin.
• Sensor ECHO pin -> NodeMCU D2 (GPIO 4) pin.
• Led Alarm Pin -> NodeMCU D3 (GPIO 0) pin.

Setup

1. Program the NodeMCU using a suitable Arduino IDE or NodeMCU programming software. You can use client/nodemcu/nodemcu.ino to upload the code.
2. Replace "WIFI_SSID" with your Wi-Fi network name (SSID) and "WIFI_PASSWORD" with your Wi-Fi password in client/nodemcu/secrets.h.
3. Create a Discord bot and obtain its token in Discord Portal. Add the token by filling in the appropriate field in server/secrets.py.
4. Install the required Python packages by running ./start.sh:

• python = 3.8.10
• discord.py = 2.3.1
• beautifulsoup4 = 4.12.2
• requests = 2.22.0

To install python packages and start discord bot service.

  chmod +x start.sh
  sudo ./start.sh

Discord Commands

• !ping
• !toggle
• !status
• !reset
